flake8-mutable 1.1.0

mutable defaults flake8 extension

flake8-mutable
--------------

#### Motivation

Python's default arguments are evaluated at definition as opposed to when the function is invoked. This leads to unexpected behavior, as mutations persist between calls. For a more detailed explanation, see [The Hitchhiker's Guide to Python](http://docs.python-guide.org/en/latest/writing/gotchas/#mutable-default-arguments).

#### Example

```
def fnc(a, b={}):
pass

foo.py:2:1: M511 - mutable default arg of type Dict
```

#### Installation

```
pip install flake8-mutable
```
