如何在Ipython输出中获取换行符 [英] How do I get a newline in a Ipython output

问题描述

考虑IPython笔记本中的以下输入：

Consider the following input in a IPython notebook:

mu = 39.95   
Z=1
Latex(r"Atomic Mass: $\quad \mu$= %0.5e Hz" %(mu))
Latex(r"Charge state: $\quad z$= %0.5e" %(Z))

我的问题分为两部分。

（A）缺少输出

从上面来源，令人惊讶的是我得到了以下结果：

From above source, Surprisingly I got the following result:

 Charge state:  z = 1.00000e+00

第一行发生了什么（即没有打印$ mu $的值）？

What happened to the first line (i.e the value of $mu$ was not printed)?

（B）缺少换行符

然而，我可以使用以下内容获得结果：

I was however able to get the result using the following:

      Latex(r"Atomic Mass: $\quad \mu$= %0.5e Hz   " %(mu) + r"Charge state: $\quad z$= %0.5e" %(Z))

但是现在，我需要上面的换行符。怎么做呢？

But now, I need a newline in the above. How does one do it?

推荐答案

默认情况下，笔记本只渲染单元格中获得的最后一个值。使用 IPython.display.display 作为增强的 print 函数来显示以下内容：

By default the notebook only renders the last value obtained in a cell. Use IPython.display.display as an augmented print function to display several things:

from IPython.display import Latex, display

mu = 39.95   
Z=1
display(Latex(r"Atomic Mass: $\quad \mu$= %0.5e Hz" % mu))
display(Latex(r"Charge state: $\quad z$= %0.5e" % Z))
