Hello
Object's attributes can be created dynamically, ie
class MyClass:
pass
obj = MyClass()
obj.test = 'foo'
but why doesn't it work with built-in classes int, float, list.... ?
L = [1, 8, 0]
L.test = 'its a list !'
(however lists are mutable, int, float ... are not)
Traceback (most recent call last):
File "<pyshell#29>", line 1, in <module>
L.test = 'its a list !'
AttributeError: 'list' object has no attribute 'test'
but it works on functions:
def funct(a,b):
....print(a+b)
funct.test = 'this is a function'
funct.test
'this is a function'
