如何在python文本文件中编写ipython命令的输出？ [英] How to write the output of ipython command in python text file?

问题描述

我想将以下ipython命令的输出捕获到一个文件中：
命令和输出区域如下：

I want to capture the output of the following ipython command into a file: commands and outputs areas follows:

`decoder.get_hyp()`

WARNING: "ngram_search.c", line 1000: </s> not found in last frame, using ++NOISE++ instead
INFO: ngram_search.c(1046): lattice start node <s>.0 end node ++NOISE++.171
INFO: ps_lattice.c(1225): Normalizer P(O) = alpha(++NOISE++:171:185) = -2003082
INFO: ps_lattice.c(1263): Joint P(O,S) = -2036704 P(S|O) = -33622
Out[7]: ('WELCOME TO MY TALK', '000000000', -36704586)

我想在我的文件中仅捕获欢迎来到我的谈话部分。

I want to capture only the part "wellcome to my talk" into my file.

推荐答案

使用IPython魔术函数 store

Use the IPython magic function store

%store foo >> a.txt # Append value of foo to file a.txt
