Python Exercises

Exercises are a great way to practice what you"ve learned and reinforce your understanding of Python. Below are various exercises categorized by difficulty level, each designed to challenge your coding skills and deepen your comprehension of Python concepts.

Beginner Exercises

These exercises are perfect for beginners who have just started learning Python. They focus on fundamental concepts like variables, control structures, and basic data types.

Exercise 1: Write a Python program to find the maximum of three numbers.

Hint: Use simple conditional statements (if, elif, else) to compare the numbers.

Exercise 2: Write a Python program to check if a number is even or odd.

Hint: Use the modulus operator (%) to determine if the number is divisible by 2.

Exercise 3: Write a Python program to print the Fibonacci sequence up to a specified number.

Hint: Start with 0 and 1, then use a loop to generate the next numbers in the sequence by summing the last two numbers.

Intermediate Exercises

These exercises are designed for those who have a basic understanding of Python and are ready to tackle more complex problems. They involve strings, loops, and data structures like lists and dictionaries.

Exercise 4: Write a Python program to count the number of vowels in a string.

Hint: Use a loop to iterate through the string and a counter to keep track of vowels (a, e, i, o, u).

Exercise 5: Write a Python program to reverse a string without using slicing.

Hint: Use a loop to build the reversed string one character at a time.

Exercise 6: Write a Python program to sort a list of dictionaries by a specific key.

Hint: Use the sorted() function with a lambda function as the key parameter to sort based on the dictionary values.

Advanced Exercises

These exercises are for advanced learners who are comfortable with Python and are looking to apply their skills to more challenging problems. They cover concepts such as file handling, algorithms, and object-oriented programming.

Exercise 7: Write a Python program to implement a basic calculator that supports addition, subtraction, multiplication, and division.

Hint: Use functions to handle different operations and a loop to allow the user to perform multiple calculations.

Exercise 8: Write a Python program to find all prime numbers within a given range.

Hint: Use a nested loop where the outer loop iterates through the range and the inner loop checks if a number is divisible by any number other than 1 and itself.

Exercise 9: Write a Python program to read data from a CSV file and display it in a tabular format.

Hint: Use the csv module to read the file and the pandas library (or simple loops) to display the data neatly.

Bonus Challenges

If you"re looking for an extra challenge, try these bonus exercises that will push your problem-solving skills to the limit:

Exercise 10: Write a Python program to implement a simple text-based game. The game should involve user interaction, decision-making, and multiple outcomes.

Hint: Use functions to handle different game scenarios and loops for user interaction.

Exercise 11: Write a Python program to analyze a text file, count the frequency of each word, and display the results sorted by frequency.

Hint: Use a dictionary to store word counts and the sorted() function to sort the results.

Exercise 12: Write a Python program to create and manage a simple database using SQLite. The program should allow the user to add, delete, update, and query records.

Hint: Use the sqlite3 module and practice SQL commands within Python.

These exercises will help you practice your Python skills and build confidence in your coding abilities. Remember to experiment, explore different solutions, and don"t hesitate to revisit the basics if you need a refresher.

Python Exercises

Exercises practice karne ka ek best tareeka hain jo aapne Python mein seekha hai usko reinforce karne ke liye.
