Python for loop?

Question

I am having trouble understanding a Python for loop. For example, here is some code I\'ve made while I\'m learning:

board = []
for i in range (0,5):
    board.ap         


        

Answer 1

Think of it as substitution.

range(0,5) is [0,1,2,3,4]. The for-loop goes through each element in the list, naming the element i.

for i in range(0,5):
    # Starts with 0
    print i # prints 0
    # now goes back, goes through next element in list: 1.

Prints 0,1,2,3,4.

In your example, i is a placeholder. It is used simply just to loop something x amount of times (in this case, five as the length of range(0,5) is 5)

Also, have fun learning python at Codecademy (I recognise the task :p)
