2. Try your best Simplified code:

return element in sub_list

3. The code should not be coupled with the data:

For example, try not to write os.getcwd() in the script to obtain the path of the current script. The path obtained in this way is the path of bash where python is executed. If the bash path of execution changes, the program will not be reproducible. The solution is: pass the path as a python execution parameter (python filename.py script_path) or pass os.path.split(os.path.realpath("__file__"))[0], so that the path acquisition will not be affected by bash Limitations on execution paths, etc. Of course, in general, the first direct transmission path method is the best.
