Does Python have something like an empty string variable where you can do:
if myString == string.empty:
Regardless, what's the most elegant way to check for empty string values? I find hard coding ""
every time for checking an empty string not as good.
Answer
Empty strings are "falsy" which means they are considered false in a Boolean context, so you can just do this:
if not myString:
This is the preferred way if you know that your variable is a string. If your variable could also be some other type then you should use myString == ""
. See the documentation on Truth Value Testing for other values that are false in Boolean contexts.
