A very simple python function to ask which option to select from a given list of options

ask_option.py

# For this to work you need to run "pip install readchar" for this script to work.
#  Also, if you are using this in a project add readchar to your requirements.txt file
import readchar


def ask_option(options):
    i = 1
    # loop through options and print
    for option in options:
        print(f"{i}). {option}")
        i += 1
    # main function loop
    # Doesn't end until a correct answer is given
    while True:
        try:
            # takes an input using readchar's readkey function
            choice = int(readchar.readkey())
            selection_validation = options[choice - 1]
            # returns the option the user selected by list index 
            # example: the user selected option 3 and it will return 2 which is the list index of the selected element
            return choice - 1
        except (ValueError, IndexError):
            print("please enter a valid option")

# Runs only if the file is being run directly rather than being imported as a module
if __name__ == '__main__':
    # run ask_option and pass a list 
    ask_option(["option 1", "option 2", "option 3", "option 4", ])
