That's not spaghetti. Not even close.
In any case, is there a reason you are reading one character at a time
instead of reading the contents of the file into memory and iterating
over the resulting string?
f = open('blah.txt', 'r')
text = f.read()
f.close()
for c in f:
# ...
If you must read one character at a time,
def reader(fileobj, blocksize=1):
"""Return an iterator that reads blocks of a given size from a
file object until EOF.
"""
# Note that iter() can take a function to call repeatedly until it
# receives a given sentinel value, here ''.
return iter(lambda: fileobj.read(blocksize), '')
f = open('blah.txt', 'r')
try:
for c in reader(f):
# ...
finally:
f.close()
