It's easy to do, but it's tricky to do it right. https://github.com/GrantEdwards/Python-curses-and-terminfo > [...] > > Here is "hello world" in bold... > > import curses > curses.setupterm() > bold = curses.tigetstr('bold').decode('ascii') > normal = curses.tigetstr('sgr0').decode('ascii') > > print(bold, 'Hello world', normal) Don't forget to use tparm() to parameterize strings for things like "move curser". Once you've parameterized the string (if needed), you've _might_ need to worry about the stuff in the string that's meant to be interpreted by tputs/putp: Quoting man tparm(3) All terminfo strings [including the output of tparm] should be printed with tputs or putp. That's becuase terminfo strings can contain escape sequences that are filterd out and interpreted by tputs/putp. The approach above only works if you only care about certain terminals, and you know that none of the terminfo strings you're using have those interal terminfo escape sequences in them [AFAIK, that's true for the linux console, xterm and the like, but not for many serial terminals.] -- Grant -- https://mail.python.org/mailman/listinfo/python-list
