Empty strings are "falsy" (python 2 or python 3 reference), 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:
if myString == "":
See the documentation on Truth Value Testing for other values that are false in Boolean contexts.

From PEP 8, in the “Programming Recommendations” section:
For sequences, (strings, lists, tuples), use the fact that empty sequences are false.
So you should use:
if not some_string:
or:
if some_string:
Just to clarify, sequences are evaluated to False or True in a Boolean context if they are empty or not. They are not equal to False or True.

July 3, 2025Python not recognizing an empty string ('') as an empty string
Firstly, I would strongly suggest avoiding phrasing like "Python not recognizing '' as empty string", since that's highly unlikely and it's probably just a bug in your program or unexpected data type in your data. It's never a compiler error, as they say. Be willing to accept you have a bug. You've provided the output of your code, but can you provide the code itself? After all, in your output it clearly looks like empty strings, but that's your output and not necessarily a source of truth. That would be the code + sample data. My debug approach for this would be to add more print statements. Check the type() of the variable you're concerned with. Print its len(). And repr(). Litter the area surrounding your if-statement with prints to understand exactly every choice that Python is making. Sometimes, I'll take the condition from an if and say print(variable == '') so that I can see the False for myself. Especially in the case of and/or conditions so I can make sure each piece is correct. One last note, [] is a list, not a dict. Dicts are {key: value}. More on reddit.com

I recently came across a problem in a textbook where these 2 were interchangeable. So what’s the difference between these 2 and when to use which? Thanks!
Edit for context:
would like to clarify the use of None in this question to initialize the while loop, how does it initialize the loop?
start = None

Well first of all, " " isn't an empty string, it's a string containing a single space. The empty string is "". But "" is only equivalent to None in a boolean context, because they are both falsy. That is, if you do: if my_var: and my_var is either of those (or 0, or an empty list, dict, etc) then it will be False. But otherwise these are completely different.

June 5, 2023 - In both of these methods, the if statement will print "String is empty" if the string s is empty. The not operator in the second example negates the "truthiness" or "falsiness" of the string, making the code slightly more concise. This is a common Pythonic way to check for empty strings.
