split-static-string (SIM905)

Derived from the flake8-simplify linter.

Fix is sometimes available.

What it does

Checks for static str.split calls that can be replaced with list literals.

List literals are more readable and do not require the overhead of calling str.split.

"a,b,c,d".split(",")

Use instead:

["a", "b", "c", "d"]

This rule's fix is marked as unsafe for implicit string concatenations with comments interleaved between segments, as comments may be removed.

For example, the fix would be marked as unsafe in the following case:

(
    "a"  # comment
    ","  # comment
    "b"  # comment
).split(",")

as this is converted to ["a", "b"] without any of the comments.
