If there is no write access, there is no need for global. Remove global statement if there is no assignment. global-variable-not-assigned: Using global for names but no assignment is done Used when a variable is defined through the "global" statement but no assignment to this variable is done. In Pylint 2.11 the global-variable-not-assigned checker now catches global variables that are never reassigned in a local scope and catches (reassigned) functions [1][2] [1] https://pylint.pycqa.org/en/latest/whatsnew/2.11.html [2] https://github.com/PyCQA/pylint/issues/1375 Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
