Prelude Python
!!! Note
This module builds on top of the shared [Programming](programming.md) module.
Python Mode
Emacs comes with Python programming support through the built-in
python-mode. Whenever you are editing Python code run C-h m to
look at the Python mode key bindings. Alternatively look at the
menu bar entries under Python. To toggle the menu bar press F12.
Anaconda Mode
Prelude bundles the powerful anaconda-mode, which provides code navigation, documentation lookup and completion for Python.
Anaconda has integration with popular modes like company and eldoc.
Syntax checking
Prelude ships with Flycheck,
an on the fly syntax checker. Flycheck has support for two Python
syntax checkers, Pylint and
Flake8. In
order to have Flycheck support on the fly syntax checking for
Python you need to have either of these installed and accessible to
Emacs. In order to manually choose a checker run C-c ! s.
Automatic insertion of file encoding comments
You can have Prelude auto-detect the encoding of a source buffer and
insert the appropriate # coding: comments. If you wish to enable
this, add the following to your configuration:
(setq prelude-python-mode-set-encoding-automatically t)
!!! Note
Previously `prelude-python` had this feature enabled by default (up to Prelude 1.1), but
it is only necessary on Python 2, because Python 3 uses utf-8
as the default file encoding. In 2020 Python 2 became deprecated, so that
functionality became mostly obsolete.
