我有一个列表的字典,数字作为键,字符串列表作为值.例如.,
my_dict = {
1: ['bush', 'barck obama', 'general motors corporation'],
2: ['george bush', 'obama'],
3: ['general motors', 'george w. bush']
}
我想要的是比较每个列表中的每个项目(对于每个键),如果该项目是另一个项目的子字符串 – 将其更改为更长的项目.所以,这是一种非常糟糕的共识解决方案.
无法真正地围绕着如何做到这一点.
这是我的想法的伪代码:
for key, value in dict:
for item in value:
if item is substring of other item in any other key, value:
item = other item
所以我的词典最终会看起来像这样:
my_dict = {
1: ['george w. bush', 'barck obama', 'general motors corporation'],
2: ['george w. bush', 'barck obama'],
3: ['general motors corporation', 'george w. bush']
}
对不起,如果我没有表达出明显的问题.
最佳答案 这是一个列表字典的事实是无关紧要的.有些字符串必须根据其他字符串进行修改.
这些是字符串:
all_strings = [s for string_list in my_dict.values() for s in string_list]
要替换字符串:
def expand_string(s, all_strings):
# compare words
matches = [s2 for s2 in all_strings
if all(word in s2.split() for word in s.split())]
if matches:
# find longest result
return sorted(matches, key=len, reverse=True)[0]
else:
# this wont't really happen, but anyway
return s
要替换一切:
result = {k: [expand_string(s, all_strings) for s in v]
for k, v in my_dict.items()}
