# set default some password characters
set_pwd = ['a', 'b', 'c', 'd', 'e']

pwd = ''
while pwd != usr_pwd:
    pwd = ''
    for _ in range(len(usr_pwd)):
        gues_pwd = set_pwd[rand.randint(0, len(set_pwd)-1)]
        pwd = gues_pwd + pwd
        print(pwd)
        print('Cracking password...please wait')
        # clean the screen
        os.system('cls')
        
print('Your password is :', pwd)

Problem 3: Python Wordclouds

# pip install wordcloud
# pip install matplotlib

from wordcloud import WordCloud
import matplotlib.pyplot as plt


# defalut some text
txt = 'Python, Django, ReactJs, Datascience, Machine learning, IoT, Deep learning, Artificial intelligence'
wordcloud = WordCloud().generate(txt)

# display the word cloud
plt.imshow(wordcloud, interpolation='bilinear')
plt.axis('off')
plt.show()

Code Explanation

This repository contains over 1000+ Python problems and their respective solutions, designed to help learners and developers improve their coding skills through practical problem-solving. Each script demonstrates how to approach a specific programming challenge using clean and efficient Python code. The necessary or required Python libraries are listed as comments in each file.

The problems range from beginner to advanced levels, covering topics such as data types, loops, functions, recursion, file handling, object-oriented programming and algorithmic problem-solving. Code files are organized in a clear and consistent format, often including comments and brief explanations to improve understanding.

To run any script:

• Make sure Python is installed on your system (Python 3.x recommended).
• Each file is standalone and can be executed using python filename.py from your terminal or code editor.
• Some scripts may include input prompts or test cases to illustrate the solution in action.
• Error handling is included where necessary to gracefully manage edge cases and unexpected inputs.
• These solutions not only help in mastering Python fundamentals but also prepare learners for coding interviews, competitive programming, and real-world problem-solving scenarios.
