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 Python
def 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 Python
def fun(): 
    pass

                    
We can use pass in empty while statement also.
# Empty loop in Python
mutex = True
while (mutex == True) :
    pass

                    
We can use pass in empty if else statements.
# Empty in if/else in Python
mutex = True
if (mutex == True) :
    pass
else :
    print("False")
