Reading a file into a multidimensional array with Python

Question

If I have a text file like this:

Hello World
How are you?
Bye World

How would I read it into a multidimensional array like this:

Answer 1

You can use map with the unbound method str.split:

>>> map(str.split, open('testFile.txt'))
[['Hello', 'World'], ['How', 'are', 'you?'], ['Bye', 'World']]

In Python 3.x, you have to use list(map(str.split, ...)) to get a list because map in Python 3.x return an iterator instead of a list.
