Using global for 'ticker' but no assignment is done - in other words, the global ticker line is not necessary and can be removed. Here is where global would be necessary: ticker = {1: 2} def remove_ticker_from_list(stock_index): global ticker ticker = "NULL_STOCK" remove_ticker_from_list('x')print(ticker) NULL_STOCK Perhaps the documentation <https://pylint.readthedocs.io/en/stable/user_guide/messages/warning/global-variable-not-assigned.html> could be updated to make it more clear? — Reply to this email directly, view it on GitHub <#9522 (comment)>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/BFVJFIJONZTXW2QURDFDPUDY2QHHDAVCNFSM6AAAAABFJGADIKVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDAMRVGI2DENZRGA> .

I think this is your example (expanded a bit to show the list definition outside the function). Python is happy with this and global isn't needed here because you are not re-assigning ticker but rather some element contained within ticker. Global would be needed if ticker were a string, for example, because the assignment inside the function wouldn't affect ticker which is defined outside the function: (venv312) ***@***.*** programming % cat example.py ticker = [1, 2, 3] def remove_ticker_from_list(stock_index): ticker[stock_index]="NULL_STOCK" remove_ticker_from_list(0)print(ticker) (venv312) ***@***.*** programming % python example.py ['NULL_STOCK', 2, 3] — Reply to this email directly, view it on GitHub <#9522 (comment)>, or unsubscribe <https://github.com/notifications/unsubscribe-auth/BFVJFILKBCMV473TY7EWLNLY2VG4TAVCNFSM6AAAAABFJGADIKVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDAMRXGE4DMMBYGE> .
