An extension for flake8 that helps to make more readable variables names.
We believe, that variable name should unmistakably shows, what it contains.
Thats why we try not to use varnames with only one symbol or not to use
too common names, such as `result`, `value` or `info`.
This extensions helps to detect such names. By default it works in
non-strict mode. You can change it with `--use-varnames-strict-mode`
parameter end extend variable names blacklist even more.
## Installation
```terminal
pip install flake8-variables-names
```
## Example
Sample file:
```python
# test.py
a = 1
foo = 2
result = a + foo
```
Usage:
```terminal
$ flake8 test.py
test.py:1:1: VNE001 single letter variable names are not allowed
test.py:2:1: VNE002 variable name should be clarified
```
## Error codes
| Error code | Description |
|:----------:|:-------------------------------------------------------:|
| VNE001 | single letter variable names like 'XXX' are not allowed |
| VNE002 | variable name 'XXX' should be clarified |
| VNE003 | variable names that shadow builtins are not allowed |
