Python Pass Statement

pass is a null operation.When it is executed nothing happens.So it is used when astatement is required syntactically but no code needs to be executed.More importantlypython is a indentation based language so needed some kind of statement to represent nothing, so code does not get messed up.

Python Pass Statement

pass is no-operation Python statement. It indicates nothing is to be done. It is just a place holder used in compund statements as they cannot be left blank.

Example of using pass statement in Python:

>>> if x==0:
...     pass
... else:
...     print "x!=0"

Python Pass Statement

In Python programming, pass is a null statement. The difference between a comment and pass statement in Python is that, while the interpreter ignores a comment entirely, pass is not ignored. But nothing happens when it is executed. It results into no operation (NOP).

Syntax of pass

pass

We generally use it as a placeholder. Suppose we have a loop or a function that is not implemented yet, but we want to implement it in the future. They cannot have an empty body. The interpreter would complain. So, we use the pass statement to construct a body that does nothing.

Example: pass Statement

for val in sequence:
    pass

We can do the same thing in an empty function or class as well.

def function(args):
    pass

class example:
    pass
