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.

I've got a fairly large script that uses a dictionary (called 'ipDic')
each
value of which is a dictionary which in turn also has values which are
not
simple types.
Instead of producing a simple list,
"""
ips = ipDic.keys()
print(ips)
"""
yields
"""

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)
