Well, the function you posted certainly doesn't change the literal
string you have inside when you change its func_name. However, the
function object *does* change.
In [1]:def g(x):
...: pass
...:
In [2]:g
Out[2]:<function g at 0x5aedf0>
In [3]:g.func_name = 'f'
In [4]:g
Out[4]:<function f at 0x5aedf0>
