- This is answered on SuperUser, and should be closed as duplicate: superuser.com/questions/110421/tab-character-width-in-terminal
- @millimoose, changing the tab stops in the terminal doesn't affect nano. This question should be specifically about nano or about setting the tab stops for Python, but not about both and not about interactively setting the tab stops with the
tabcommand, which doesn't affect all programs.
- I'm using mint and when I set tabsize from 8 to 4 in /etc/nanorc and go back to the file, I'm still getting 8 spaces in the tab, I even tried to copy that nanorc file to ~/. but that doesn't work, closed and reopened terminal, but still I can't get 4 spaces on the tab unless I use nano -T4.

- Ok never mind. I find nanorc in /etc directory. thanks though
- @FallenSatan, generally you should avoid editing /etc/nanorc, unless you need to perform system-wide customizations. Create ~/.nanorc if it doesn't already exist and put your customizations there.
- Note that in the above answer you need to add the line "set tabsize 4", not "set tabspace 4"
- sudo nano will not take ~/.nanorc for an obvious reason; so the command-line flag is a more practical solution to the problem.
- Link is dead, have you got an alternative explanation?
