Example 1: python initialize list length n
Creating an empty list:
>>> l = [None] * 10
>>> l
[None, None, None, None, None, None, None, None, None, None]
Example 2: create a list of a certain length python
# 2.X only. Use list(range(10)) in 3.X.
>>> l = range(10)
>>> l
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Example 3: length of list python
thistuple = ("apple", "banana", "cherry")
print(len(thistuple))
Example 4: how to find length of list python
my_list = [1,2,3,4,5,6,7,8,9,10]
length_of_list = len(my_list)
Example 5: python list of size
li = [None] * 5 # [None, None, None, None, None]
li = [0] * 5 # [0, 0, 0, 0, 0]
