Interactive
Helper module for setting up interactive Diofant sessions.
AST/string-based transformations, provided here, could be used in IPython to reduce boilerplate while interacting with Diofant due to the Python language syntax.
- diofant.interactive.printing.init_printing(no_global=False, pretty_print=None, **settings)[source]
Initializes pretty-printer depending on the environment.
- Parameters:
no_global (boolean) – If True, the settings become system wide; if False, use just for this console/session.
pretty_print (boolean or None) – Enable pretty printer (turned on by default for IPython, but disabled for plain Python console).
**settings (dict) – A dictionary of default settings for printers.
Notes
This function runs automatically for wildcard imports (e.g. for
from diofant import *
) in interactive sessions.Examples
>>> from diofant.abc import theta >>> sqrt(5) sqrt(5) >>> init_printing(pretty_print=True, no_global=True) >>> sqrt(5) ___ ╲╱ 5 >>> theta θ >>> init_printing(pretty_print=True, use_unicode=False, no_global=True) >>> theta theta >>> init_printing(pretty_print=True, order='grevlex', no_global=True) >>> y + x + y**2 + x**2 2 2 x + y + x + y
