while c = f.read(1)

I have a Python snippet:

f = open("blah.txt", "r")
while True:
c = f.read(1)
if c == '': break # EOF
# ... work on c

Is some way to make this code more compact and simple? It's a bit
spaghetti.

This is what I would ideally like:

f = open("blah.txt", "r")
while c = f.read(1):
# ... work on c

But I get a syntax error.

while c = f.read(1):
^
SyntaxError: invalid syntax

And read() doesn't work that way anyway because it returns '' on EOF
and '' != False. If I try:

f = open("blah.txt", "r")
while (c = f.read(1)) != '':
# ... work on c

I get a syntax error also. :(

Is this related to Python's expression vs. statement syntactic
separation? How can I be write this code more nicely?

Thanks
