Thanks Danny!
That was an awesome explanation.

Thank Danny,
That's much more clear.
But I still don't understand what's happening with:
if line.strip()
Is that stripping the line of white space at the same time that it is
testing it?

Two features about Python:
1. Strings are immutable, so the above is computing what a
whitespace-stripped line would look like. So that means that
'line.strip()' is doing just a com

The code you found is one of several syntactic shortcuts in Python,
which allow creating a sequence directly from an expression in your
cod

Hi Jared,
Let me rewrite this without the list comprehension, while preserving behavior.

Hello,
Could someone explain why and how this list comprehension with strip()
works?
f = open('file.txt')
t = [t for t in f.readlines() if t.strip()]
f.close()
print "".join(t)
I had a very long file of strings filled with blank lines I wanted to
remove. I did some Googling and found the above co
