This document discusses input and print functions in Python. It explains that the print function displays information to the user and includes examples of printing different data types. It also explains that the input function accepts information from the user, stores it in a variable, and can include a prompt. Examples are provided of getting both string and numeric input and converting the input to other data types like integers. The document also covers simple formatting options for print like printing on new lines, adding separators, or printing on the same line.
