+Command-line usage
+------------------
+
+.. versionadded:: 3.13
+
+The :mod:`!random` module can be executed from the command line.
+
+.. code-block:: sh
+
+   python -m random [-h] [-c CHOICE [CHOICE ...] | -i N | -f N] [input ...]
+
+The following options are accepted:
+
+.. program:: random
+
+.. option:: -h, --help
+
+   Show the help message and exit.
+
+.. option:: -c CHOICE [CHOICE ...]
+            --choice CHOICE [CHOICE ...]
+
+   Print a random choice, using :meth:`choice`.
+
+.. option:: -i <N>
+            --integer <N>
+
+   Print a random integer between 1 and N inclusive, using :meth:`randint`.
+
+.. option:: -f <N>
+            --float <N>
+
+   Print a random floating point number between 1 and N inclusive,
+   using :meth:`uniform`.
+
+If no options are given, the output depends on the input:
+
+* String or multiple: same as :option:`--choice`.
+* Integer: same as :option:`--integer`.
+* Float: same as :option:`--float`.
