bad-str-strip-call (PLE1310)#

Derived from the Pylint linter.

What it does#

Checks duplicate characters in str.strip calls.

Why is this bad?#

All characters in str.strip calls are removed from both the leading and trailing ends of the string. Including duplicate characters in the call is redundant and often indicative of a mistake.

In Python 3.9 and later, you can use str.removeprefix and str.removesuffix to remove an exact prefix or suffix from a string, respectively, which should be preferred when possible.


# Evaluates to "foo".
"bar foo baz".strip("bar baz ")

Use instead:

# Evaluates to "foo".
"bar foo baz".strip("abrz ")  # "foo"


# Evaluates to "foo".
"bar foo baz".removeprefix("bar ").removesuffix(" baz")
