In the following, `choose_method` selects the best method to carry out a command, out of the following list of available methods:
>>> methods = [
    (0, "/calculate"),
    (1, "/random-number"),
    (2, "/email"),
    (3, "/search"),
    (4, "/music"),
    (5, "/create")
    ]
>>> command = """
How to eat an oyster?
"""
>>> method = ChatBot().ask(command).choose_method(methods)
>>> print(method[0])

This code will print the index of the most suitable method, which in this case is what? Write only the single number.
