PYTHON PRACTICE QUESTIONS

 

1. Write a program that checks if a number is even or odd using the modulo operator and an if-else statement.
2. Create a loop that prints the first 10 multiples of 3.
3. Use a nested loop to print a simple pattern of asterisks (e.g., a right-angled triangle).
4. Write a program that uses the break statement to exit a loop when a specific condition is met.
5. Implement a simple calculator that performs basic arithmetic operations based on user input.                                                                                                                              #PROBLEMS ON FUNCTIONS

6.  Write a function that takes two numbers as arguments and returns their sum, difference, product, and quotient.

7.  Create a function with default arguments that calculate the area of a rectangle.

8.  Write a lambda function that returns the square of a number, and use it in a list comprehension to square all numbers in a given list.

9.  Implement a function that uses *args to find the maximum number among the arguments passed.
