| 2 | |
| 3 | A small number of constants live in the builtin namespace. They are: |
| 4 | |
| 5 | \begin{datadesc}{False} |
| 6 | The false value of the \code{bool} type. |
| 7 | \versionadded{2.3} |
| 8 | \end{datadesc} |
| 9 | |
| 10 | \begin{datadesc}{True} |
| 11 | The true value of the \code{bool} type. |
| 12 | \versionadded{2.3} |
| 13 | \end{datadesc} |
| 14 | |
| 15 | \begin{datadesc}{None} |
| 16 | The sole value of \code{NoneType}. \code{None} is frequently used to |
| 17 | represent the absence of a value, as when default arguments are not passed |
| 18 | to a function. |
| 19 | \end{datadesc} |
