如何通过sympy在ipython笔记本中进行漂亮的打印？

Question

我尝试过pprint，，print前者只能打印Unicode版本，而后者却不能打印出漂亮的照片。

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)

Answer 1

您需要使用显示：

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，仍然建议显式导入它。
