typeError: isinstance() arg 2 must be a type or tuple of types >>>

Question

>>> names=[\'jill\',\'jack\']
>>> isinstance(names,list)
Traceback (most recent call last):
  File \"\", line 1, in 

        

Answer 1

Apply this one :

if isinstance(names, type(list)):

Answer 2

But this works in Python (v3.7.1:260ec2c36a, Oct 20 2018, 14:05:16) [MSC v.1915 32 bit (Intel)] on win32：

>>> names=['jill', 'jack']
>>> isinstance(names, list)
True

Answer 3

You've stomped on list by assigning to a local variable of the same name. Don't do that.
