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, 2025empty string returns True upon checking if its contained in a non empty string
Yes, empty strings are in any other string. Like the empty set is a subset of any other set. I feel like there’s probably many easier ways to do what you’re trying to do here (which seems to be looking for the string “di” within another string without case sensitivity?) but to minimize the change to your approach, if you want to initialize previous so it returns false without raising a type error, you could initialize it with a long string that can’t possibly be in the search string. After the first iteration it will be set by the loop code and won’t be empty again. More on reddit.com

June 7, 2025[Help] Getting blank string from subprocess.check_output
I remember having some similar issues. I checked my notes and I wound up doing it like this.
cmd = 'echo Some command string'
result = subprocess.run(cmd.split(), stdout=subprocess.PIPE, stderr=subprocess.PIPE)
stdout = result.stdout.decode('utf-8')
stderr = result.stderr.decode('utf-8')
status = 'COMPLETE' if result.returncode == 0 else 'FAILED' More on reddit.com 4

June 1, 2018What's the most pythonic way of checking if variable is None or empty string ""?
Both None and "" are falsy values so simply if not variable: will cover both those cases. This doesn't explicitly check for those values but if you're just checking for something not being set this is probably the way to go. More on reddit.com

July 6, 2021 -
I'm trying to constantly check against any of those values but I don't want to keep repeating myself in code.
if variable is None or variable == "": do stuff
What are my options? Can I create somehow a class and check against that class?
if variable is MyNewClass: do stuff
How would I write such a class?
Thanks!

How to Check if a String is Empty or None in Python
June 5, 2023 - If both conditions are false (meaning the string is not None and it's not empty), it will print "String is not empty and not None". Python has two equality operators, == and is. While they sometimes work the same, they are not identical. The == operator checks for value equality, while is checks for identity, meaning that it checks whether the operands are the same object.
