6.4 The pass statement

 

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)
