No, the first is checking for str equal to a space character, the second
for the empty string. You need to get those glasses checked *grin*
Note to the original poster: the more "pythonic" way of doing this check
will be:
if s and s.strip():
# do something with non-empty s
else:
# s is either empty or all whitespace
Don't use "str" as a variable name, as it will over-ride the built-in type
str. This will eventually cause you problems, when you try something like
this:
>>> str(5)
'5'
>>> str = "Hello world" # shadow the built-in
>>> str(5)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: 'str' object is not callable
