line-length is not working as intended

[gjambaisivanandham]

I am using black version 24.3.0 and have set line-length = 88 in my config file, however running black . command doesn't modify the lines of code that are over 88 characters.

Ex:
Before running black
str = "this is the longest text in the history of mankind that I have seen in the world for all the good and bad things"

After running black the result is still the same. I don't see any error it says x file(s) left unchanged.

Here is my config file

max-line-length = 88
extend-ignore = E203, W503, W291
exclude = .git,__pycache__,./.venv

[tool.black]
line-length = 88```

python version: `3.11.6`

Long strings are currently unaffected by the current Black stable style. You can use the --unstable flag to enable it and other unstable/preview features, as described in the documentation. However, this particular feature may not stay around for much longer - see #4208
