Python pass statement | Example with loop, function & class

Python pass statement is a null operation. Means nothing will happen on its execution. The interpreter does not ignore a pass statement.

So Nothing will happen when the pass is executed and result results in no operation. It can use in condition statements where you can’t leave an empty block.

But why you have to use a pass statement in python?

The pass statement is used when you only want a function without implementation. It will use of future implementation of functions, loops, etc.

don’t write the implementation of a function but you want to implement it in the future.

Q: How to write a function with nobody in Python?

Answer: Simply use a function name without implementing it and use pass keyword same as below code.

Important: Python has the syntactical requirement that code blocks (after ifexceptdefclass etc.) cannot be empty.

Pass refers to ignore….as simple as it is ….if the given condition is true and the next statement is pass it ignores that value or iteration and proceed to the next line ….. Example
