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)

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, order='grevlex', no_global=True)
>>> y + x + y**2 + x**2
 2    2
x  + y  + x + y
