将 .txt 文件转换为 .csv ，其中每行转到一个新列，每个段落转到一个新行

Question

我在处理 txt 和 json 数据集方面比较陌生。我在 txt 文件中有一个对话数据集，我想将其转换为 csv 文件，并将每一行转换为一列。当下一个对话框开始时（下一段），它从一个新行开始。所以我得到

格式的数据

Header = ['Q1' , 'A1' , 'Q2' , 'A2' .......]

这里是供参考的数据（此文件为txt格式）： dialog data

Answer 1

CSV 文件是由逗号分隔的字符串列表，行之间用换行符 (\n) 分隔。

由于这种简单的布局，通常不适合包含其中可能包含逗号的字符串，例如对话。

也就是说，对于您的输入文件，可以使用正则表达式用逗号替换任何单个换行符，这有效地满足了“每个新行转换成一列，每个新段落转换成新行”的要求.

import re

with open('input.txt', 'r') as reader:
    text = reader.read()

text = re.sub(r"(...)\n", r",", text)
print(text)

with open('output.csv', 'w') as writer:
    writer.write(text)
