__name__ and __qualname__ , see:
def fn():
pass
class C(object):
pass
>>> fn.__name__
"fn"
>>> fn.__qualname__
"fn"
>>> C.__name__
"C"
>>> C.__qualname__
"C"
What is the difference between __name__ and __qualname__ ?
It's exactly the same thing in basic usage. In the cited example it does not change. But when you have classes or functions nested there changes. Using a more complex example, see that only the higher-level class or function that is in the global namespace produces the same result, the others change and only __qualname__ produces a full pathname, called < in> fully qualified name . __name__ only gives the basic name without a "last name", which can be ambiguous when the element of the code is nested.
class C:
def f(): pass
class D:
def g(): pass
print(C.__qualname__)
print(C.f.__qualname__)
print(C.D.__qualname__)
print(C.D.g.__qualname__)
def f():
def g(): pass
return g
print(f.__qualname__)
print(f().__qualname__)
