Which of the following statements is false? $(4\mathrm{.}2\mathrm{.}2)$

A function definition begins with the def keyword, followed by the function name, a set of parentheses and a colon $(.$

Like pariable identifiers, by convention function names should begin with a lowercase letter and in multiword names underscores should separate each word.

The indented lines after the colon $($ are the function's suite, which consists of an optional docstring followed by the statements that perform the function's task.

The required parentheses in a function definition contain the function's parameter list$-$a commaseparated list of parameters representing the data that the function needs to perform its task.
