Imagine you're working on a text-to-speech system, which reads phone numbers aloud. The input phone number will consist solely of digits. Your task is to print the name of each digit on a new line for the system to read them one by one.
Tip 1: You can store the digit names in a container, e.g. in a list with the names from 0 to 9 digits = ['zero', 'one', 'two', ..., 'nine'], and refer to each digit name by its index, i.e. sequence number (starting with 0) of an element in the list, then, in this case, digits[2] equals to 'two', etc. Mind the type, an index should be an integer, not a string. Recall, that in order to convert a string to an integer you need to use int() function.
Tip 2: It may be a good idea to store the initial input as a string, not as an integer, even though it only consists of digits.
