如何获取python列表中每个重复单词的距离？

Question

A = ['dcv', 'asc', 'dfg','lku','drf','asd','dcv','tfd','cfv','asc','dds','ast','lku']
'dcv': 6
'asc': 8
'lku': 9

我想知道的是Python语法中重复单词之间的距离，将其划分为有规律的间隔。

Answer 1

在迭代时，只需使用dict来存储值的索引。如果已经看到一个值，则打印距离：

A = ['dcv', 'asc', 'dfg','lku','drf','asd','dcv','tfd','cfv','asc','dds','ast','lku']

d = {}
for idx, value in enumerate(A):
    if value in d:
        print(f'{value}: {idx - d[value]}')
    d[value] = idx

输出：

dcv: 6
asc: 8
lku: 9

Answer 2

下面的代码将告诉您列表中类似单词的索引。

A = ['dcv', 'asc', 'dfg','lku','drf','asd','dcv','tfd','cfv','asc','dds','ast','lku']

d = {}
for i, word in enumerate(A):
    if word in d:
        print(f'{word}: {i - d[word]}')
    d[word] = i
