Does an equivalent of override exist for nested functions?

Question

If I have this function, what should I do to replace the inner function with my own custom version?

def foo():
    def bar():
        # I want to change this         


        

Answer 1

You can pass it in as an optional parameter

def foo(bar=None):
    def _bar():
        # I want to change this
        pass
    if bar is None:
        bar = _bar
