Hey there,
This is my first letter here, I'll try my best to explain the problem.
First of all, I ran into this "problem" several times. I find
str.split() a bit confusing. First of all, this is a corner case, but
can happen like every day.
print("".split()) # returns []
print("".split(" ")) # returns ['']
print("".split("\t")) # returns ['']
print("".split("\n")) # returns ['']
print("".splitlines()) # returns []
So using split with or without a separator matters a lot, even when we
use the same whitespace character split() uses. I think it is quite
annoying. My idea is to return a list with an empty string in all
cases mentioned above.
With probably millions (at least!) of uses of str.split in real code,
there's no way we can change this behavior.
You might be able to argue for an additional parameter to control this,
but I personally think the chances of confusion are too high. What I
usually do is write a wrapper for str.split if I don't like how it's
behaving.
