在每个数字后用新行将单元格的输出保存在jupyter笔记本中 [英] Saving the output of a cell in jupyter notebook with a new line after each number

问题描述

我将单元格的输出保存为txt文件，如下所示:

I saved output of a cell as a txt file as follows:

第一个单元格:

%%capture cap --no-stderr
print(q)

第二个单元格:

with open('output.txt', 'w') as f:
    f.write(cap.stdout)

下面是我想保存的一小段代码:

Below is a small piece of code that I wanted to save:

#%%
np.seterr(over='ignore')

a = np.uint32(1664525)
c = np.uint32(1013904223)
seed = np.uint32(1)

rng = LCG(seed, a, c)
q = [rng.next() for _ in range(0, 2500000)]

文件已保存，但是生成的数字用逗号分隔，但是我希望每个生成的数字都用换行而不是逗号分隔

The file is saved, however the generated numbers are separated by a comma, but I want each generated number to be separated by a new line, not a comma

我尝试将"w"更改为"a"并按如下所示添加"\ n"，但这对我不起作用.

I tried to change "w" to "a" and add "\ n" as below but it does not work for me.

with open('output.txt', 'a') as f:
    f.write("\n")

推荐答案

%%capture在此单元格中捕获其旁边所有代码，因此您可以打印出列表中的所有元素.

%%capture capture all the out of the code beside it in this cell, so you can print out all the elements from the list.

%%capture cap --no-stderr
for i in q:
    print(i)

---

with open('output.txt', 'w') as f:
    f.write(cap.stdout)

cap.stdout处理整个%%capture捕获的内容，因此当您尝试添加\n时，它将无法正常工作.

cap.stdout handle what %%capture captured as a whole, so when you tried to add \n, it won't work.

是您想要的吗?
