I didn't understand for and in

Question

Help me i didn't understand for and in :/

Answer 1

for in loop, is used to iterate through the elements of an object.

Example: Say you want to circle through the elements of a list and print their squares.

nums = [2, 4, 1, 8, 7]
for num in nums:
print(nums**2)

Output
========
4
16
1
64
49

On the first iteration of the loop, the variable "num" is given the value 2, it then prints out 2², which is 4.
On the second iteration of the loop, the variable "num" is given the value "4" it then prints out 4² which is 16.

The loop goes on like that doing the same thing for every element in the list.
