Type() can hamper productivity

This code insight detects each time type() is used in code

Why you should care

The function isinstance is the best-equipped to handle type checking because it supports inheritance (e.g. an instance of a derived class is an instance of a base class, too). Therefore  isinstance should be used whenever type comparison is required

Business Impacts

Type() negatively affects productivity bcause it creates improper comparisons
