Python Pass Statement
In Python programming,
pass is a null statement typically used as a placeholder. In contrast to a
comment statement which is ignored by the Python interpreter, a
pass statement is not ignored but nothing happens when it is executed. It results in No Operation (NOP).
Consider the case of a loop or function that we have not fully implemented yet. Without a body, the Python interpreter will complain but with a
pass statement we can return to it later.
while True: pass
letters = ['a', 'b', 'c', 'd', 'e'] for l in letters: pass
pass statements are frequently used with functions and classes when you want to continue thinking at a more abstract level and later implement the code in full:
def function(args): pass # Remember to implement later class EmptyClass: pass
