在python中查找多个重复的文本，计算重复的数量和unique以及第一个重复文本的索引

Question

请帮帮我。 我的文件如下所示：

This is a cat
we are working at BusinessBrio
Gitu is my beloved cat
Jery is also a cat
Boni is a nice dog
Gitu is my beloved cat
we are working at BusinessBrio
This is a cat
we are working at BusinessBrio
Gitu is my beloved cat
Jery is also a cat
Boni is a nice dog
Gitu is my beloved cat
we are working at BusinessBrio

我需要这样的输出：

[[1,'we are working at BusinessBrio',4],[2,'Gitu is my beloved cat',4],[0,'This is a cat',2],[3,'Jery is also a cat',2],[4,'Boni is a nice dog',2]]

更多的输出必须根据重复计数按降序排序

Answer 1

It is not clear how to separate sentences since there is no punctuation. But suppose we know how to. Then just use Counter from collection.

data = '''
This is a cat
we are working at BusinessBrio
Gitu is my beloved cat
Jery is also a cat
Boni is a nice dog
Gitu is my beloved cat
we are working at BusinessBrio
This is a cat
we are working at BusinessBrio
Gitu is my beloved cat
Jery is also a cat
Boni is a nice dog
Gitu is my beloved cat
we are working at BusinessBrio
 '''
li = data.split('\n')

from collections import Counter

pp(Counter(li))

Counter({'we are working at BusinessBrio': 4,
         'Gitu is my beloved cat': 4,
         'Boni is a nice dog': 2,
         'This is a cat': 2,
         'Jery is also a cat': 2,
         '': 1,
         ' ': 1})
