Python Projects – Beginner, Intermediate and Advanced Levels Of Using Python

In this 『Python Projects』 blog, let us have a look at 3 levels of Python projects that you should learn to master Python and test your project analysis, development and handling skills on the whole. Many people would agree if I say Python is really fun to learn and fiddle around with.

Let』s begin this Python Projects blog by checking out the following list of topics:

  • Introduction to Python
  • How to go about learning Python Projects?
  • Beginner Python Projects: Hangman Game with Python
  • Intermediate Python Projects: Working with Graphs in Python
  • Advanced Python Projects: Machine Learning using Python

It will only be fair if I give you a small introduction to Python.

Introduction To Python

Python is a high-level, object-oriented, interpreted programming language, which has garnered worldwide attention. Stack Overflow found out that 38.8% of its users mainly use Python for their projects.

Python was created by a developer called Guido Van Rossum.

Python is and always has been easy to learn and master. It is very beginner friendly and the syntax is extremely simple to read and follow through. This definitely makes us all happy and what』s amazing is that python has millions of happy learners across the globe!

According to the website』s survey, Python』s popularity surpassed that of C# in 2018 – just like it surpassed PHP in 2017. On the GitHub platform, Python surpassed Java as the second-most used programming language, with 40% more pull requests opened in 2017 than in 2016.

This makes  Python certification one of the most sought-after programming certifications.

How To Go About Learning Python Projects?

The answer to this question is fairly simple and straightforward. It all starts with learning the basics and all the fundamentals of Python. This is basically a measurement index to know how comfortable you are working with Python.

The next prime step involves taking a look at the basic and easy code to familiarize yourself with the syntax and the flow of logic in the code. This is a very important step and helps set a strong foundation for later on as well.

After this, you should definitely look at what python is being used for in real life. This will play a major role in finding out why you want to learn Python in the first place.

If that』s not the case then you will learn about the projects and you can implement certain strategies for the projects that you will consider starting on your own.

Followed by this is definitely to look at what projects you can tackle your current knowledge of Python. Diving into the depth of Python will help you assess yourself at every stage.

Projects are basically used to solve a problem at hand. If providing solutions to the various simple and complex problems are your kind of a thing, then you should definitely consider working on Python projects.

After you』ve got your hands dirty with a couple of projects, you will be one step closer to mastering python. This is important because you will be able to spontaneously implement what you』ve learned on something as simple as writing a calculator program all the way till helping achieve artificial intelligence.

Let』s begin by checking out the first level of Python projects.

Beginner Python Project: Hangman Game with Python

The best beginner project we can consider is the game of Hangman. I am sure the majority of you reading this Python Projects blog has played Hangman at one point of time in your life. To put it in just one single statement, the main goal here is to create a 「guess the word」 game. As simple as it sounds, it has certain key things you need to note. 

  • The user needs to be able to input letter guesses.
  • A limit should also be set on how many guesses they can use.
  • Keep notifying the user of the remaining turns.

This means you』ll need a way to grab a word to use for guessing. Let us keep it simple and use a text file for the input. The text file consits of the words from which we have to guess.

You will also need functions to check if the user has actually inputted a single letter, to check if the inputted letter is in the hidden word (and if it is, how many times it appears), to print letters, and a counter variable to limit guesses.

Key Concepts to keep in mind for this Python Project:

  • Random
  • Variables
  • Boolean
  • Input and Output
  • Integer
  • Char
  • String
  • Length
  • Print


from string import ascii_lowercase
from words import get_random_word

def get_num_attempts():
    """Get user-inputted number of incorrect attempts for the game."""
    while True:
        num_attempts = input(

            num_attempts = int(num_attempts)
            if 1 <= num_attempts <= 25:
                return num_attempts
                print('{0} is not between 1 and 25'.format(num_attempts))
        except ValueError:
            print('{0} is not an integer between 1 and 25'.format(

def get_min_word_length():
    """Get user-inputted minimum word length for the game."""
    while True:
        min_word_length = input(
            'What minimum word length do you want? [4-16] ')
            min_word_length = int(min_word_length)
            if 4 <= min_word_length  0 and not word_solved:
        # Print current game state

        print('Attempts Remaining: {0}'.format(attempts_remaining))
        print('Previous Guesses: {0}'.format(' '.join(wrong_letters)))

        # Get player's next letter guess
        next_letter = get_next_letter(remaining_letters)

        # Check if letter guess is in word
        if next_letter in word:
            # Guessed correctly
            print('{0} is in the word!'.format(next_letter))

            # Reveal matching letters
            for i in range(len(word)):
                if word[i] == next_letter:
                    idxs[i] = True
            # Guessed incorrectly
            print('{0} is NOT in the word!'.format(next_letter))

            # Decrement num of attempts left and append guess to wrong guesses
            attempts_remaining -= 1

        # Check if word is completely solved
        if False not in idxs:
            word_solved = True

    # The game is over: reveal the word
    print('The word is {0}'.format(word))

    # Notify player of victory or defeat
    if word_solved:
        print('Congratulations! You won!')
        print('Try again next time!')

    # Ask player if he/she wants to try again
    try_again = input('Would you like to try again? [y/Y] ')
    return try_again.lower() == 'y'

if __name__ == '__main__':
    while play_hangman():


"""Function to fetch words."""

import random

WORDLIST = 'wordlist.txt'

def get_random_word(min_word_length):
    """Get a random word from the wordlist using no extra memory."""
    num_words_processed = 0
    curr_word = None
    with open(WORDLIST, 'r') as f:
        for word in f:
            if '(' in word or ')' in word:
            word = word.strip().lower()
            if len(word) < min_word_length:
            num_words_processed += 1
            if random.randint(1, num_words_processed) == 1:
                curr_word = word
    return curr_word

Now that we saw how we can tackle a beginner project like Hangman, let us step it up a little and check out an intermediate Python Project next. 

Intermediate Python Project: Working With Graphs In Python

The best way to get started with learning intermediate stages of programming in Python is to definitely start working with the libraries that Python supports.

There is literally 『n』 number of libraries that you can make use of while coding in Python. Some are very easy and straightforward while some might take some time to grasp and master.

Here are some of the top libraries you can consider starting out with:

  • NumPy
  • SciPy
  • Pandas
  • Matplotlib

NumPy is for scientific computing on a whole.

Scipy uses arrays like basic data structure used for linear algebra, calculus, and other similar concepts.

Pandas are used for dataframes and Matplotlib is to visualize data in the form of graphs and notations.

The best possible usage of Python is for data visualization. As helpful as numeric data output is, there are many requirements of a visual representation of the data.

By visual representation, it is just a generalization. Anything ranging from creating your front-end or a Graphical User Interface (GUI) to plotting numeric data as points on a graph.

Matplotlibis used to plot data points on a graph. And  M atplotlib is a plotting library for the Python programming language and its numerical mathematics extension NumPy. It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK+. 

There are many options for doing 3D plots in Python, but here are some common and easy ways using Matplotlib .

In general, the first step is to create a 3D axes, and then plot any of the 3D graphs that best illustrates the data for a particular need.  In order to use Matplotlib , the mplot3d toolkit that is included with the Matplotlib installation has to be imported:

from mpl_toolkits import mplot3d

Then, to create a 3D axes you can execute this code:

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
ax = plt.axes(projection=』3d』)

Top Python Projects You Should Consider Learning

It is inside this 3D axes that a plot can be drawn, it is important to know what type of plot (or combination of plots) will be better to describe the data.

At this point in time, you need to note that this comprises our base for further plotting.

Points and Lines:

The following image combines 2 plots, one with a line that goes through every point of the data, and others that draw a point on each of the particular 1000 values on this example.

The code is actually very simple when you try to analyze it. We have made use of standard trigonometric functions to plot a set of random values to obtain our projection in 3 dimensions. 


ax = plt.axes(projection=』3d』)# Data for a three-dimensional line
zline = np.linspace(0, 15, 1000)
xline = np.sin(zline)
yline = np.cos(zline)
ax.plot3D(xline, yline, zline, 『gray』)# Data for three-dimensional scattered points
zdata = 15 * np.random.random(100)
xdata = np.sin(zdata) + 0.1 * np.random.randn(100)
ydata = np.cos(zdata) + 0.1 * np.random.randn(100)
ax.scatter3D(xdata, ydata, zdata, c=zdata, cmap=』Greens』);

3D Contour Plots:

The input for the contour plot is a bit different than for the previous plot, as it needs the data on a two-dimensional grid.

Note that on the following example that after assigning values for x and y, they are combined on a grid by executing 「np.meshgrid(x, y)」 and then the Z values are created from executing the function f(X ,Y ) with the values of the grid (Z=f(X ,Y )).

Again, basic 3d plot simplified in the following code:

def f(x, y):
    return np.sin(np.sqrt(x ** 2 + y ** 2))

x = np.linspace(-6, 6, 30)
y = np.linspace(-6, 6, 30)

X, Y = np.meshgrid(x, y)
Z = f(X, Y)fig = plt.figure()
ax = plt.axes(projection='3d')
ax.contour3D(X, Y, Z, 50, cmap='binary')

On the previous graphs, the data was generated in order, but in real life sometimes the data is not ordered, for those cases, the surface triangulation is very useful as it creates surfaces by finding sets of triangles formed between adjacent points.

Surface Triangulation:

theta = 2 * np.pi * np.random.random(1000)
r = 6 * np.random.random(1000)
x = np.ravel(r * np.sin(theta))
y = np.ravel(r * np.cos(theta))
z = f(x, y)
ax = plt.axes(projection=』3d』)
ax.plot_trisurf(x, y, z,cmap=』viridis』, edgecolor=』none』);

Now that we are familiar with how we can expand our reach on learning Python by looking at external libraries, we can go ahead and check out the next level of Python Projects which is the Advanced Level .

Advanced Projects With Python

Python has vast applications – Everything from 「Hello World」 all the way to achieving Artificial Intelligence.

There are virtually unlimited projects you can work on using Python but here are the major ones that you can consider if you want to dive into the heart of Python.

  • Machine Learning with PyTorch, TensorFlow, Keras and  whatever Machine Learning libraries you like.
  • Computer vision using OpenCV and PIL.
  • Creating and publishing your own pip module with tests and documentation.

Among all of these, my favorite is definitely to work on Machine Learning and Deep Learning. Let us look at a very nice use-case to learn Python in-depth.

Implementation Of CIFAR10 Using TensorFlow In Python

Let』s  trainnetwork to classify images from the  CIFAR10 Dataset using a Convolution Neural Network built-in  TensorFlow .

Top Python Projects You Should Consider Learning

Consider the following  Flowchart to  understand the  working of the use-case:

Top Python Projects You Should Consider Learning

Let us break down this flowchart into simple terms:

  • We first load images into our program
  • These images are stored in a place where the program can access it
  • We need Python to make sense of the information that is present so we do the process of normalization
  • We define the foundation of the neural network 
  • Defining the loss function to ensure we obtain maximum accuracy on the dataset
  • Training the actual model to learn something about the data that it has seen all this while
  • testing the model to analyze the accuracy and iterate through the training process to achieve better accuracy

This use-case is broken into 2 programs. One is to Train the network and other is to test the network.

Let us first train the network.
