python - 分隔大写字母上的连接单词

Question

使用 Python，我必须编写一个基本上“清理”数据文本文件的脚本。到目前为止，我已经删除了所有不需要的字符或将它们替换为可接受的字符(例如，破折号 - 可以替换为空格)。现在我已经到了必须将连接在一起的单词分开的地步。这是文本文件前 15 行的片段

AccessibleComputing  Computer accessibility
AfghanistanHistory  History of Afghanistan
AfghanistanGeography  Geography of Afghanistan
AfghanistanPeople  Demographics of Afghanistan
AfghanistanCommunications  Communications in Afghanistan
AfghanistanMilitary  Afghan Armed Forces
AfghanistanTransportations  Transport in Afghanistan
AfghanistanTransnationalIssues  Foreign relations of Afghanistan
AssistiveTechnology  Assistive technology
AmoeboidTaxa  Amoeba
AsWeMayThink  As We May Think
AlbaniaHistory  History of Albania
AlbaniaPeople  Demographics of Albania
AlbaniaEconomy  Economy of Albania
AlbaniaGovernment  Politics of Albania

我想要做的是将大写字母出现处连接的单词分开。例如，我希望第一行看起来像这样:

Accessible Computing  Computer accessibility

脚本必须获取文件输入并将结果写入输出文件。这就是我目前所拥有的，但根本不起作用! (不确定我是否走在正确的道路上)

import re

input_file = open("C:\\Users\\Lucas\\Documents\\Python\\pagelinkSample_10K_cleaned2.txt",'r')
output_file = open("C:\\Users\\Lucas\\Documents\\Python\\pagelinkSample_10K_cleaned3.txt",'w')

for line in input_file:
    if line.contains('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'):
        newline = line.

output_file.write(newline)

input_file.close()
output_file.close()

Answer 1

我建议使用以下正则表达式分割单词:

import re, os

input_file = 'input.txt'
output_file = 'output.txt'

with open(input_file, 'r') as f_in:
    with open(output_file, 'w') as f_out:
        for line in f_in.readlines():
            p = re.compile(r'[A-Z][a-z]+|\S+')

            matches = re.findall(p, line)
            matches = ' '.join(matches)

            f_out.write(matches+ os.linesep)

假设 data.txt 包含您在帖子中粘贴的文本，它将打印:
