Doesn't run Python

### Description

So I was trying to run some Python code, and I do the cmd+I shortcut to run, and it doesn't run.

### Steps to Reproduce

1. Write some Python, such as:
```py
print('hello world')
```
2. Press run (cmd+I)

**Expected behavior:**

`hello world`
_Note: I don't remember what the actual output would look like because I don't have any screenshots of Atom with any Python code being successfully ran._

**Actual behavior:**

_Note: This was tested on existing files as well (didn't work) and HTML (worked). I dont know any other languages it supports, so I didn't test those._

**Reproduces how often:**

Every time I run a .py file

### Versions

Tested in Atom versions 1.48.00 x64 and 1.60.00 x64
macOS Monterey 12.3.1 on a late 2014 Mac mini
