Python – pass Keyword

The pass keyword as the name suggests does nothing. It is used as a dummy place holder whenever a syntactical requirement of a certain programming element is to be fulfilled without assigning any operation.
In other words, the pass statement is simply ignored by the Python interpreter and can be seen as a null statement. It is generally used as a dummy statement in a code block, for example in the if or else block.

Example: pass in for loop
for num in range(1,6):        
    if num==3:
        print ("Num =  {} ".format(num))



Num = 1
Num = 2
Num = 4
Num = 5

The following is the definition of a function which will not do any operation when executed:

def myfunction():


The pass statement is commonly used in the early stages of program development to form a skeleton of the entire code.
Initially, the programmer will create place holders with no operation using pass for various conditional statements, functions, classes etc., and eventually will fill their functionality.
