Sorry I am a very beginner in python.
Thanks for your help.

>Solution :

use the len() function

arr = [1,2,3]
print(len(arr))

prints 3

len(s)

Return the length (the number of items) of an object. The argument may be a sequence (such as a string, bytes, tuple, list, or range) or a collection (such as a dictionary, set, or frozen set).
