For Loop in Python
The for loop is used to iterate over a sequence (like a list, tuple, or string) or a range of numbers. It’s one of the fundamental tools for iteration in Python. Here are some beginner-friendly exercises to help you practice using for loops.
Practice Problems
Problems Index
- Print numbers from 1 to 10 using a
forloop. - Input a number and print its multiplication table.

- Print all even numbers between 1 and 50.
- Input a number and calculate its factorial.
- Print a pattern of stars for
nrows (e.g., a right-angled triangle). - Input a number and check if it’s prime using a
forloop. - Print all numbers divisible by 3 and 5 in the range 1 to 100.
