absolutely, some programming languages allow you to omit parentheses when calling a function with no arguments. for instance, in python, you can write print instead of print(). does syntactic sugar always make code shorter? not always. while syntactic sugar often aims to make code more concise...
The difference between mutable and immutable objects is that mutable objects can be modified, while immutable objects can’t be altered once created. Python lists are mutable, allowing you to change, add, or remove elements. Strings in Python are immutable, meaning you can’t change their ...
