When I type sep and press Enter, I get a line like this:

// ******

However, the comments in python start with #, so I have to edit the line to change it to

*******

How can I save new snippets in order to speed up my typing? Is it possible at all?

@ruimac

... you can add keyboard shortcuts in iOS Settings/General/Keyboard, don't know if that helps.

What program are you using to use snippets!??
