Python pass statement

In this article, you'll learn about pass statement. It is used as a placeholder for future implementation of functions, loops, etc.
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.

However, nothing happens when pass 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

# pass is just a placeholder for
# functionality to be added later.
sequence = {'p', 'a', 's', 's'}
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
