Using sudo with Python script

Many answers focus on how to make your solution work, while very few suggest that your solution is a very bad approach. If you really want to “practice to learn”, why not practice using good solutions? Hardcoding your password is learning the wrong approach!

If what you really want is a password-less mount for that volume, maybe sudo isn’t needed at all! So may I suggest other approaches?

  • Use /etc/fstab as mensi suggested. Use options user and noauto to let regular users mount that volume.

  • Use Polkit for passwordless actions: Configure a .policy file for your script with <allow_any>yes</allow_any> and drop at /usr/share/polkit-1/actions

  • Edit /etc/sudoers to allow your user to use sudo without typing your password. As @Anders suggested, you can restrict such usage to specific commands, thus avoiding unlimited passwordless root priviledges in your account. See this answer for more details on /etc/sudoers.

All the above allow passwordless root privilege, none require you to hardcode your password. Choose any approach and I can explain it in more detail.

As for why it is a very bad idea to hardcode passwords, here are a few good links for further reading:
