如何通过sympy在ipython笔记本中进行漂亮的打印?

问题描述

我尝试了pprint，print，前者只能打印Unicode版本，而后者却不能打印漂亮的图像.

I tried pprint, print, the former only prints Unicode version, and the latter doesn't do pretty prints.

from sympy import symbols, Function
import sympy.functions as sym
from sympy import init_printing
init_printing(use_latex=True)
from sympy import pprint
from sympy import Symbol

x = Symbol('x')

# If a cell contains only the following, it will render perfectly.
(pi + x)**2

# However I would like to control what to print in a function,
# so that multiple expressions can be printed from a single notebook cell.
pprint((pi + x)**2)

推荐答案

您需要使用display:

you need to use display:

from IPython.display import display

display(yourobject)

它将选择适当的表示形式(text/LaTex/png ...)，在默认情况下，默认情况下会导入最新版本的IPython(6.0+)显示，仍然建议显式导入.

It will choose the appropriate representation (text/LaTex/png...), in recent enough version of IPython (6.0+) display is imported by default, still we recommend to explicitly import it.
