Turns out this doesn't seem to be valid, because python interprets str in df.apply(str) as a type instead of a method. At least this is the case in 3.10+

研究方向
Investigate the unnecessary lambda rule in pylint, specifically the good example in doc/data/messages/u/unnecessary lambda/good/pandas.py. The issue indicates that `df.apply(str)` is incorrectly flagged because `str` is interpreted as a type rather than a method. Check the rule logic and test with Python 3.10+. There is already an assignee, so coordinate if needed.
