Document Summary

Chatbots: a program that processes conversations (in text or speech. ) Input(): allows the user to provide a prompt string. User = input () user is basically the label of input. The name of the label can be anything. Variable: a name that refers to a value. Can contain letters, numbers, and underscores (should start with a letter, by convention we use lowercase) Cannot contain spaces or symbols such as !, $, #, $. Cannot be one of the reserved keywords such as print. In code, we use user as a name referring to the value entered by the user of the program. Adding more features such as greetings or a question. Comment = [] : allows you to put many comments that can be used to reply back. Import means to tell the program to grab something. A dot is calling a function that is predefined. The process of combining two strings is called string concatenation.
