Answer 1

In Python, for is used to move through a collection of values. For example:

for letter in 'abcde':
print(letter)

Each letter will be printed one after another, then the code moves on.

With while you give a condition; as soon as it's not true anymore, the loop stops.

x = ''
while x != 'yes':
print('Will you help me?')
x = input()

The user will be asked over and over until they type 'yes'.
