For logging purposes I want to retrieve the fully qualified class name of a Python object. (With fully qualified I mean the class name including the package and module name.)
I know about x.__class__.__name__, but is there a simple method to get the package and module?
With the following program
#!/usr/bin/env python
import foo
def fullname(o):
klass = o.__class__
module = klass.__module__
if module == 'builtins':
return klass.__qualname__ # avoid outputs like 'builtins.str'
return module + '.' + klass.__qualname__
bar = foo.Bar()
print(fullname(bar))
and Bar defined as
class Bar(object):
def __init__(self, v=42):
self.val = v
the output is
$ ./prog.py
foo.Bar
If you're still stuck on Python 2, you'll have to use __name__ instead of __qualname__, which is less informative for nested classes - a class Bar nested in a class Foo will show up as Bar instead of Foo.Bar:
def fullname(o):
klass = o.__class__
module = klass.__module__
if module == '__builtin__':
return klass.__name__ # avoid outputs like '__builtin__.str'
return module + '.' + klass.__name__
