What's new in Pylint 3.0.3?

Release date: 2023-12-11

False Positives Fixed

• Fixed false positive for unnecessary-lambda when the call has keyword arguments but not the lambda.

  Closes #9148

• Fixed incorrect suggestion for shallow copy in unnecessary-comprehension

  Example of the suggestion:
  #pylint: disable=missing-module-docstring
  a = [1, 2, 3]
  b = [x for x in a]
  b[0] = 0
  print(a) # [1, 2, 3]

  After changing b = [x for x in a] to b = a based on the suggestion, the script now prints [0, 2, 3]. The correct suggestion should be use list(a) to preserve the original behavior.

  Closes #9172

• Fix false positives for undefined-variable and unused-argument for
  classes and functions using Python 3.12 generic type syntax.

  Closes #9193

• Fixed pointless-string-statement false positive for docstrings
  on Python 3.12 type aliases.

  Closes #9268

• Fix false positive for invalid-exception-operation when concatenating tuples
  of exception types.

  Closes #9288

Other Bug Fixes

• Fix a bug where pylint was unable to walk recursively through a directory if the
  directory has an __init__.py file.

  Closes #9210
