IOTk

If you're looking for a Python module that provides a set of functions to effectively handle user input and output in the command line, look no further than IOTk, aka the Input/Output Toolkit. With this module, you'll find a variety of handily named input functions, including ask_string, ask_int, ask_yes_no, ask_filename, ask_folder, and ask_regex. Each function is expertly designed to help you get valid input, with the added bonus of being able to customize error messages so your users don't get frustrated or confused.

But that's not all. IOTk also provides several powerful output functions to make your life easier. For example, with print_dict, you can neatly print the keys and values in a dictionary, with an impressive array of formatting options. Likewise, with print_list, you can print the items in a list in a similarly customizable manner. And if you need to wrap text to a certain number of columns, there's wrap_str, which is a powerful word-wrapping function that gets the job done right.

Finally, to make sure your output looks its best, there's print_string. This function provides a thick wrapper around wrap_str, allowing you to align and fill your output however you need. Overall, if you're looking for a comprehensive, user-friendly toolkit that will help you handle input and output like a pro, IOTk is definitely worth a closer look.
