Flake8 Builtins plugin
|
|
======================
|
|
Check for python builtins being used as variables or parameters.
|
|
|
|
Imagine some code like this::
|
|
|
|
def max_values(list, list2):
|
|
max = list[0]
|
|
for x in list:
|
|
if x > 0:
|
|
max = x
|
|
|
|
all_values = list()
|
|
all_values.append(max)
|
|
|
|
max = list2[0]
|
|
for x in list2:
|
|
if x > 0:
|
|
max = x
|
|
all_values.append(max)
|
|
|
|
return all_values
|
|
|
|
max_values([3, 4, 5, ], [5, 6, 7])
|
|
|
|
The last statement is not returning ``[5, 7]`` as one would expect,
|
|
instead is raising this exception::
|
|
|
|
Traceback (most recent call last):
|
|
File "test.py", line 17, in <module>
|
|
max_values([3,4,5], [4,5,6])
|
|
File "bla.py", line 6, in max_values
|
|
all_values = list()
|
|
TypeError: 'list' object is not callable
|
|
|
|
**Why?** Because ``max_value`` function's first argument is ``list`` a Python builtin.
|
|
Python allows to override them, but although could be useful in some really specific use cases,
|
|
the general approach is to **not** do that as code then can suddenly break without a clear trace.
|
|
|
|
Example
|
|
-------
|
|
Given the following code::
|
|
|
|
def my_method(object, list, dict):
|
|
max = 5
|
|
min = 3
|
|
zip = (4, 3)
|
|
|
|
The following warnings are shown (via flake8)::
|
|
|
|
test.py:1:15: A002 "object" is used as an argument and thus shadows a python builtin, consider renaming the argument
|
|
test.py:1:23: A002 "list" is used as an argument and thus shadows a python builtin, consider renaming the argument
|
|
test.py:1:29: A002 "dict" is used as an argument and thus shadows a python builtin, consider renaming the argument
|
|
test.py:2:5: A001 "max" is a python builtin and is being shadowed, consider renaming the variable
|
|
test.py:3:5: A001 "min" is a python builtin and is being shadowed, consider renaming the variable
|
|
test.py:4:5: A001 "zip" is a python builtin and is being shadowed, consider renaming the variable
|
|
|
|
Install
|
|
-------

|
|
|
|
$ pip install flake8-builtins
