python - 拆分成两列，将txt文本转换成csv文件

Question

我有以下数据：

Graudo. A selection of Pouteria caimito, a minor member...

TtuNextrecod. A selection of Pouteria caimito, a minor member of the Sapotaceae...

我想把它分成两列

Column1       Column2
------------------------------------------------------------------------------
Graudo        A selection of Pouteria caimito, a minor member...
TtuNextrecod  A selection of Pouteria caimito, a minor member of the Sapotaceae...

需要代码方面的帮助。谢谢，

import csv # convert
import itertools #function for a efficient looping

with open('Abiutxt.txt', 'r') as in_file:
    lines = in_file.read().splitlines() #returns a list with all the lines in string, including the line breaks

    test = [line.split('. ')for line in lines ] #split period....but...need work

    print(test)


    stripped = [line.replace('', '').split('. ')for line in lines ]

    grouped = itertools.izip(*[stripped]*1)
    with open('logtestAbiutxt.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('Column1', 'Column2'))

        for group in grouped:
            writer.writerows(group)

我不确定你是否需要在这里拉拉链。只需遍历输入文件的每一行，跳过空行，按句点分割并写入 csv 文件：

import csv


with open('Abiutxt.txt', 'r') as in_file:
    with open('logtestAbiutxt.csv', 'w') as out_file:
        writer = csv.writer(out_file, delimiter="\t")
        writer.writerow(['Column1', 'Column2'])

        for line in in_file:
            if not line.strip():
                continue

            writer.writerow(line.strip().split(". ", 1))

笔记：

• 注意：指定一个制表符作为分隔符，但您可以适当更改它
• 感谢@PatrickHaugh 的想法，". "因为您的第二列也可能包含句点，所以第一次出现时会分裂。
