Worked Example Exercise Challenge On Python Basics

Here are 30 Python challenge exercises based on the topics we have covered so far:

Basic Python Program: Operators and Expressions

1. Calculate the area of a rectangle using width and height as inputs.
2. Swap two variables without using a third variable.
3. Find the maximum of three numbers using comparison operators.
4. Convert Celsius to Fahrenheit using the formula $$ F = C \times \frac{9}{5} + 32 $$.

Data Types: Integer, Floating-Point, and String

5. Create a program that concatenates two strings and prints the result.
6. Replicate a string a specified number of times based on user input.
7. Check the type of a variable and print whether it is an integer, float, or string.
8. Take two integers as input and print their sum, difference, product, and quotient.

Input Function and len() Function

9. Write a program that takes user input for their name and prints the length of the name.
10. Ask for a sentence from the user and print the number of words in that sentence.
11. Create a program that takes a string input and prints it in reverse.

Comparison Operators

12. Write a program to check if two numbers are equal or not using both == and =.
13. Create a program that compares two strings and prints whether they are equal or not.
14. Check if a number is greater than 10 but less than 20 using comparison operators.

Boolean Operators

15. Write a program that checks if a number is even or odd using boolean operators.
16. Create an expression that evaluates to true if either of two conditions is met (e.g., age > 18 OR has permission).
17. Combine comparison operators with boolean operators to check if a number is between 1 and 100.

Flow Control: Conditional Statements

18. Write a program that prints “Adult” if age is 18 or older, otherwise print “Minor”.
19. Create a loop that prints numbers from 1 to 10, but skips the number 5 using continue.
20. Write a program that counts down from 10 to 1, using break to stop at zero.

Loops: For Loops and While Loops

21. Use a for loop to print all even numbers between 1 and 20.
22. Write a while loop that sums numbers until the sum exceeds 100.
23. Create a multiplication table for numbers 1 through 10 using nested loops.

Advanced Challenges

24. Write a function that takes a list of numbers as input and returns the largest number in the list.
25. Create a program that checks if a word is a palindrome, ignoring spaces and punctuation.
26. Implement a simple calculator that performs addition, subtraction, multiplication, and division based on user choice.
27. Write a function to find the factorial of a number using recursion.

Bonus Challenges

28. Create a program that generates Fibonacci series up to n terms, where n is provided by the user.
29. Write code to remove duplicates from a list while maintaining order.
30. Implement basic error handling in your calculator program to manage division by zero errors gracefully.
