Python on Linux

Ubuntu comes with Python installed by default, as do many other versions of Linux and UNIXeven Mac OS X comes with Python preinstalled. Part of this is due to convenience because it is such a popular scripting language and it saves having to install it later if the user wants to run a script.

The Python binary is installed into /usr/bin/python; if you run that, you enter the Python interactive interpreter where you can type commands and have them executed immediately. Although PHP also has an interactive mode (use php a to activate it), it is neither as powerful nor as flexible as Python's.

As with Perl, PHP, and other scripting languages, you can also execute Python scripts by adding a shebang line (#!) to the start of your scripts that point to /usr/bin/python and then setting the file to be executable.

The third and final way to run Python scripts is through mod_python, which you can install through synaptic.

For the purposes of this introduction, we use the interactive Python interpreter because it provides immediate feedback on commands as you type them.
