Python Private Key Checker. What is wrong with me?

1. When i run this code looks like no problem but suddenly crashed and it wrongly find same adress with different private keys.
2. Also when i made exe with auto-py-to-exe. program did not run with "NameError Name 'Adress' is not defined.Failed to execute scrip.

But i defined error. İ am new here does anyone know how can i solve this problems ?
