What is pass in Python?

The pass is a null operation in python. When it is executed, nothing happens. It is useful as a placeholder when a statement is required syntactically, but no code needs to be executed.

The pass statement is useful when you don’t write the implementation of a function but you want to implement it in the future. for example,

def addNum(num1, num2):
  # Implementation will go here 
  pass # Pass statement
addNum(2, 2)
