February 14, 2023Why does my empty dictionary not evaluate to false?
Because an empty dictionary is not equal to false. In a boolean context, it's falsey (treated as false), but that's different from it literally comparing as the same as false. I keep thinking if a list or dictionary is empty it automatically evaluates to none. No, it's just equal to an empty list/dictionary. It will only evaluate to None if you use it in an expression like: {} or None # None More on reddit.com

Empty dictionaries evaluate to False in Python:
>>> dct = {}
>>> bool(dct)
False
>>> not dct
True
>>>
Thus, your isEmpty function is unnecessary. All you need to do is:
def onMessage(self, socket, message):
if not self.users:
socket.send("Nobody is online, please use REGISTER command" \
" in order to register into the server")
else:
socket.send("ONLINE " + ' ' .join(self.users.keys()))

Here are three ways you can check if dict is empty. I prefer using the first way only though. The other two ways are way too wordy.
test_dict = {}
if not test_dict:
print "Dict is Empty"
if not bool(test_dict):
print "Dict is Empty"
if len(test_dict) == 0:
print "Dict is Empty"

How to check if a dictionary is empty in Python | Replit
You can directly compare your dictionary to an empty dictionary literal, {}, using the equality operator ==. This expression returns True if your dictionary contains no key-value pairs and False otherwise. It's an explicit and visually clear way to perform the check. While this approach works, it's slightly less efficient because Python has to create a new empty dictionary object for the comparison.

How to Create and Check Empty Dictionary in Python
September 7, 2025 - That does not mean it is None because None means nothing in memory, while an empty dictionary has an object. empty_dict = {} print(empty_dict) # Output: {} print(type(empty_dict)) # Output: <class 'dict'> The “{}” literal is the fastest approach because Python’s bytecode directly interprets it, and it does not require a function call, which reduces the overhead.

:dict_a does not equal False, and dict_a={1:"data"} does not equal True. Use dict_a={} if dict_a: ## shorthand for if len(dict_a) > 0 print("True") else: print("False")
