Linting

• E1101 (import-error) because unites files function correctly, which means that the file successfully imported
• W0603 (global-statement) because we needed the usage of global statements to keep track of last update time
• C0413 (wrong-import-position) because in order for the app.py to work correctly we have to import a table after some sqlalchemy configuration code
• W1508 (invalid-envvar-default)
• C0200 (consider-using-enumerate) because we prefer to use range instead of enumerate
• R0801 (duplicate-code)
• E1101 (no-member)
