When customizing pylint's message templates, the following fields are available:
```yaml
path: relative path to the file
abspath: absolute path to the file
line: line number
column: column number
module: module name
obj: object within the module (if any)
msg: text of the message
msg_id: the message code (eg. I0011)
symbol: symbolic name of the message (eg. locally-disabled)
C: one letter indication of the message category
category: fullname of the message category
```

Pylint: Message Format Fields

By default, pylint outputs messages with the following template:
'{msg_id}:{line:3d},{column}: {obj}: {msg}'

One can customize how their messages are being presented with pylint by running it with the following argument:
```bash
$ pylint --msg-template=<formatted string>
```

University of Michigan - Ann Arbor

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"

Pylint: Changing Message Display

If you aren't aware of what a specific message from pylint means and need more information, you can run the following command with the message's symbolic name to learn more:
```bash
$ pylint --help-msg=missing-module-docstring
:missing-module-docstring (C0114): *Missing module docstring*
  Used when a module has no docstring. Empty modules do not require a docstring.
  This message belongs to the basic checker.
