Python将对列表转换为字典 [英] Python convert pairs list to dictionary

问题描述

我有一个大约50个字符串的列表，其中一个整数表示它们在文本文档中出现的频率.我已经格式化了它，如下所示，并且正在尝试创建此信息的字典，第一个单词是值，键是旁边的数字.

I have a list of about 50 strings with an integer representing how frequently they occur in a text document. I have already formatted it like shown below, and am trying to create a dictionary of this information, with the first word being the value and the key is the number beside it.

string = [('limited', 1), ('all', 16), ('concept', 1), ('secondly', 1)]

我到目前为止的代码:

my_dict = {}
for pairs in string:
    for int in pairs:
       my_dict[pairs] = int

推荐答案

Python的 dict() 函数是为转换tuple s的list而设计的，它就是您所拥有的:

Like this, Python's dict() function is perfectly designed for converting a list of tuples, which is what you have:

>>> string = [('limited', 1), ('all', 16), ('concept', 1), ('secondly', 1)]
>>> my_dict = dict(string)
>>> my_dict
{'all': 16, 'secondly': 1, 'concept': 1, 'limited': 1}
