Each line of pylint output can be broken into 4 parts. We can break them down with the following example:

simplecaesar.py:3:0: W0301: Unnecessary semicolon (unnecessary-semicolon)

The first part of the output will be the name of the file with a given mesasge, such as simplesaesar.py

This will be followed by the row and column, and then the id of the message, such as "W0301".

The message will be followed by the actual message itself, and then a symbolic name for the message, which in this example is "unnecessary-semicolon"

Understanding Pylint Output

pylint can be run on individual files, or entire directories containing several python files. Some example output of what pylint can do can be found below:
```bash
$ pylint simplecaesar.py
************* Module simplecaesar
simplecaesar.py:7:0: C0103: Constant name "shift" doesn't conform to UPPER_CASE naming style (invalid-name)
simplecaesar.py:11:0: C0103: Constant name "encoded" doesn't conform to UPPER_CASE naming style (invalid-name)
simplecaesar.py:15:12: C0103: Constant name "encoded" doesn't conform to UPPER_CASE naming style (invalid-name)

Pylint is a powerful command line tool used to check for errors in python code. Pylint tries to enforece the PEP8 style guide, and can also report back certain errors within the code and recommend edits to resolve them.
