pycharm builtin unresolved reference
built-in, pycharm, python
Solution
You have the language version set to Python 3; `raw_input` in Python 2 is just `input` in Python 3 (`input` in Python 2 is `eval(input())` in Python 3: What's the difference between raw_input() and input() in python3.x?).
To select the Python version, see: How to select Python version in PyCharm?
Problem
I'm using PyCharm and just trying out some simple stuff. When I try to use `raw_input()`, the editor is showing an unresolved reference error. I'm not sure what the issue is. Has anyone seen this before?
