How do I get the string with name of a class?
What method do I call to get the name of a class?
Asked by: Andrew657 | Posted: 27-01-2022
Answer 1
In [1]: class Test:
...: pass
...:
In [2]: Test.__name__
Out[2]: 'Test'
Answer 2
It's not a method, it's a field. The field is called __name__. class.__name__ will give the name of the class as a string. object.__class__.__name__ will give the name of the class of an object.
Answer 3
I agree with Mr.Shark, but if you have an instance of a class, you'll need to use its __class__ member:
>>> class test():
... pass
...
>>> a_test = test()
>>>
>>> a_test.__name__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: test instance has no attribute '__name__'
>>>
>>> a_test.__class__
<class __main__.test at 0x009EEDE0>
Answer 4
From Python 3.3 and onwards we can use __qualname__ field for both classes & functions.
It differs from __name__ field for nested objects like class defined in other class
>>> class A:
class B:
pass
>>> A.B.__name__
'B'
>>> A.B.__qualname__
'A.B'
which may be quite useful.

In [8]: str('2'.__class__)
Out[8]: "<type 'str'>"
In [9]: str(len.__class__)
Out[9]: "<type 'builtin_function_or_method'>"
In [10]: str(4.6.__class__)
Out[10]: "<type 'float'>"
Or, as was pointed out before,
In [11]: 4.6.__class__.__name__
Out[11]: 'float'
