How to write an empty function in Python – pass statement?
In C/C++ and Java, we can write empty function as following
// An empty function in C/C++/Java
void fun() { }
In Python, if we write something like following in Python, it would produce compiler error.
# Incorrect empty function in Pythondef fun(): |
Output :
IndentationError: expected an indented block
In Python, to write empty functions, we use pass statement. pass is a special statement in Python that does nothing. It only works as a dummy statement.
# Correct way of writing empty function # in Pythondef fun(): pass |
We can use pass in empty while statement also.
# Empty loop in Pythonmutex = Truewhile (mutex == True) : pass |
We can use pass in empty if else statements.
# Empty in if/else in Pythonmutex = Trueif (mutex == True) : passelse : print("False") |
