Flake8 plugin that forbids implicit str/bytes literal concatenations
Project description
flake8-no-implicit-str-concat-in-list
Flake8 plugin that forbids implicit str/bytes literal concatenations inside literals such as lists, sets and tuples.
# NG
a = ["aaa",
"bbb"
"ccc"]
# OK
print('foobar' 'baz')
a = ["aaa",
"bbb"
+ "ccc"]
b = b'abcdef'
s = ('abc'
'def')
Installation
Install via pip:
pip install flake8-no-implicit-str-concat-in-list
Violation Codes
The plugin uses the prefix ICL
, short for no implicit string concatenation in lists.
Unfortunately flake8 only allows three characters for the error code prefix.

Other Plugins & Linters
- flake8-implicit-str-concat
Flake8 plugin to encourage correct string literal concatenation.
This plugin is different from
flake8-no-implicit-str-concat-in-list
because this plugin prefers implicit concatenations over explicit+
operators when concatenating literals even inside lists, tuples and set literals. - wemake-python-styleguide
Set of strict flake8 rules with several plugins as dependencies.
It implements
WPS326 Found implicit string concatenation
, which also checks implicit string concatenations, as one of the many rules it defines. - pylint
This linter has
implicit-str-concat
rule. By default it only looks for occurrences of implicit concatenations on the same line, but it has--check-str-concat-over-line-jumps=y
option to enable checking of concatenations over multiple lines. - flake8-no-implicit-concat
This linter has
no_implicit_concat
rule. It also looks for implicit string concatenation but in all contexts, not just in lists.
Development
Use tools like Pipenv:
pipenv run python -m pip install -e .[dev]
pipenv run make check
