It givesfalsefor 1, because here 1 meanstrueand 0 meansfalse. So simply, if we apply one more not operator in front of this, it will becomedouble notand will give the reverse value of (!expression). As seen above, (!false) will givetrue, but (!!false) will givefalse. Example for...
Learn how to use Python's if __name__ == "__main__" idiom to control code execution. Discover its purpose, mechanics, best practices, and when to use or avoid it. This tutorial explores its role in managing script behavior and module imports for clean an
In the code snippet, we defined a function “fibonacci” that takes “n” as its argument in integer form. During the execution, if “n” is 0 or 1, the function will return 0 or 1, respectively. Alternatively, if the condition is not met, the function recursively invokes itself with ...
In Short: It Makes Importing Python Modules Faster Even though Python is aninterpreted programming language, its interpreter doesn’t operate directly on your Python code, which would be very slow. Instead, when yourun a Python scriptorimporta Python module, the interpreter compiles your high-leve...

(equals) to apply superscript formatting. other software or applications may use different key combinations, so it is best to consult the documentation or search online for specific instructions based on the program you are using. how can i use superscript in mathematical equations or formulas? in...
__name__inapp.py:__main__ Copy This is how Python knows whether to run the code inside theif name equals mainblock. If the name is set to main, it runs. If not, it doesn't. Functions, methods and components Here's a slightly more advanced Python script to demonstrate the use of...
In our blog we look at Python's __name__ variable. Is it just Python's cumbersome way of doing main()? We show how the simplicity of __name__ is valuable, particularly when in a module running an expensive, extensive calculation.
Imagine a set of natural numbers. You can take any number and check whether it equals itself or not: Copy >1==1true If this check returnstruefor all the natural numbers, then equality is “reflexive” for them?(in math they say “on”, not “for” —“equality is reflexiveonthe set...
Today, let’s discuss something that’s all over the place in many code bases: what doesif __name__ == '__main__'do in Python? The statementif __name__ == '__main__':checks if variable__name__is set to the string value'__main__'which holds only within the main source fil...
