随着以下程序
#! /usr/bin/env python
import foo
def fullname(o):
# o.__module__ + "." + o.__class__.__qualname__ is an example in
# this context of H.L. Mencken's "neat, plausible, and wrong."
# Python makes no guarantees as to whether the __module__ special
# attribute is defined, so we take a more circumspect approach.
# Alas, the module name is explicitly excluded from __qualname__
# in Python 3.
module = o.__class__.__module__
if module is None or module == str.__class__.__module__:
return o.__class__.__name__ # Avoid reporting __builtin__
else:
return module + '.' + o.__class__.__name__
bar = foo.Bar()
print fullname(bar)
并Bar定义为
class Bar(object):
def __init__(self, v=42):
self.val = v
输出是
$ ./prog.py
foo.Bar
