6.4 The pass statement
-
Download entire grammar as text.
pass_stmt ::= "pass"
pass is a null operation -- 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, for example:
def f(arg): pass # a function that does nothing (yet) class C: pass # a class with no methods (yet)
