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
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
