query_yes_no(question, default=”yes”)

Ask a yes/no question via raw_input() and return their answer.

  • “question” is a string that is presented to the user.

  • “default” is the presumed answer if the user just hits <Enter>. It must be “yes” (the default), “no” or None (meaning an answer is required of the user).

  • The “answer” return value is one of “yes” or “no”.

query_yes_no_all(question, default=”yes”)

Ask a yes/no/all question via raw_input() and return their answer.

  • “question” is a string that is presented to the user.

  • “default” is the presumed answer if the user just hits <Enter>. It must be “yes” (the default), “no”, “all” or None (meaning an answer is required of the user).

  • The “answer” return value is one of “yes”, “no”, or “all”.

def query_yes_quit(question, default=”quit”)

Ask a yes/quit question via raw_input() and return their answer.

  • “question” is a string that is presented to the user.

  • “default” is the presumed answer if the user just hits <Enter>. It must be “yes” (the default), “quit” or None (meaning an answer is required of the user).

  • The “answer” return value is one of “yes” or “quit”.

wait(sec)

title(mytitle)

subtitle(mysubtitle)

Takes ‘mysubtitle’, centers it, and prints it in bright (white) letters on a normal (black) background.

progressbar (class)

This class is used to create and then update a ‘progress bar’, like:

[================>                                                      ] 17 / 70

progressbar(current=0, maximum=100, bar_color=colorama.Fore.GREEN)

Creates a progress bar class. Prints the progress bar.

progressbar.update(currently=None)

Updates the value of the progress bar and prints it.

progressbar.reset()

Sets the value of the progress bar to 0 (zero) and prints it.
