in python and most other languages, you would use a for loop

Here is an example

​

for i in range(5):

    print(i)

The above prints 0 to 4.

Note it ends before 5 and not 5, because zero indexing.

​

The range function has a few other optional arguements

range(start,stop,step)

start means what number to start on (default 0)

range(1,5) = 1 2 3 4

stop is what number to stop on.

step is how much to increase each time. (default 1)

range(1,5,2) = 1 3
