Python: 文本文件到字典

Question

我想将文本文件按行方式转换为键值对。我的文本文件

21:54:26     From Rohan luthra : yes
21:54:36     From Ankit : yup
21:54:36     From Ankit : yup
21:55:04     From Rajesh : shubh shubh bolo sir

我想做的是转换成像

这样的键值对

{'Rohan luthra' : 'yes',
'Ankit' : 'yup,}

像这样^ 我找不到任何合适的解决方案。我做了什么

with open(x) as f:
    lines = f.readlines()
    with open(x, 'r') as f:
        for line in f:
            splitLine = line.split()
            temp_dict[(splitLine[0])] = " ".join(splitLine[2:])
            # Dirty hack to remove timestamp
            temp_array = temp_dict.values()
            chat_dict = dict(s.split(':') for s in temp_array)
            pp.pprint(temp_dict)

但是当遇到一行中有两个“:”时，这个方法就失败了。它returns:

Traceback (most recent call last):
  File "filereader.py", line 37, in <module>
    most_talkative()
  File "filereader.py", line 32, in most_talkative
    chat_dict = dict(s.split(':') for s in temp_array)
ValueError: dictionary update sequence element #35 has length 3; 2 is required

Answer 1

with open(x) as f:
    lines = f.readlines()
    with open(x, 'r') as y:
        for line in y:
            splitLine = line.split()
            temp_dict[(splitLine[0])] = " ".join(splitLine[2:])
            # Dirty hack to remove timestamp
            temp_array = temp_dict.values()
            chat_dict = dict(s.split(':')[:2] for s in temp_array)

这似乎行得通！ @Alan Leuthard 给出的解决方案

循环仅适用于 20 行，而实际文件有 100 多行+

返回 len(lines) 给出实际编号。文件中的行数，即 119.

Answer 2

以下内容根据提供的文件格式的任意长度版本创建字典。请记住，每个键只能有 1 个值，因此重复的键将被后面的值覆盖。

x = 'path\to\file'
temp_dict = dict()
chat_dict = dict()
with open(x, 'r') as f:
    for line in f:
        splitLine = line.split()
        temp_dict[(splitLine[0])] = " ".join(splitLine[2:])
        # Dirty hack to remove timestamp
        temp_array = temp_dict.values()
        chat_dict.update(dict(s.split(':')[:2] for s in temp_array))
print(chat_dict)
