In Python there is no actual need or reason to define lists (or any mutable variables) with pre-set sizes. Only immutable ones kind of have to, as you declare them as constant for the runtime.
Still, if you need to instantiate a list of a given dimension you can use a list expression to do that, like:
l = [None for i in range(20)]
or simply:
l = [None] * 20

On the other hand, if you need an array type - you can use Python numpy module, which supports array-like tensors (they are still called arrays though :)
import numpy as np
a = np.empty(20) # will create an array of size (20,) with an interesting value representation of "emptiness" ;)

You can easily write one:
padding_char = '*'
def setLength(s, max_length):
return (s + padding_char * max_length) [:max_length]
exampleA=setLength('I love it dude!',15)
print(exampleA)
exampleB=setLength('I love it!',15)
print(exampleB)
exampleC=setLength('I love it dude! How can we add more to this string?',15)
print(exampleC)
prints :
I love it dude!
I love it!*****
I love it dude!

Using str.format() might be an option:
'{0:\u0000<15.15}'.format('I love it dude!')
where \u0000 is the character to fill up to the minimum length, < is the alignment of the text (in this case left), the first 15 the minimum length, the second 15 the maximum length.
