Modifying .exe file using python?

[personx1212]

hi , i have been searching for a way to modify .exe files using python, to make changes to the exe (inject user code), i found examples using other languages, but how can i do this using python? i know it is possible to alter the exe file because i used a tool to password-protect the exe file, and it embeds the password prompt code to the exe it self and the exe size changes after this, so there must be away...

thanks for your help....
