将字符串拆分为相同字母的块 [英] Split string into chunks of same letters

问题描述

这很简单，我就是做不到！在这个例子中，我想要做的就是将下面的字符串分成彼此相邻的相同字母块，例如在下面的示例中:test = "AAATGG", 将被拆分为 "AAA","T","GG".我一直在尝试不同的方法，下面举一个例子.感谢您的帮助.

this is easy, I just can't do it! In this example, all I want to do is split the string below into chunks of same letters that are beside each other, e.g. in the below example: test = "AAATGG", would be split into "AAA","T","GG". I've been trying different ways, one example below. I'd appreciate the help.

我知道这个想法是遍历字符串，如果下一个字母与当前字母相同，则继续，否则，中断并打印并重新开始，我无法正确实现它.

I know the idea is to go through the string, if the next letter is the same as the current letter, continue on, else, break and print and start again, I just can't implement it properly.

test = "AAATGG"
TestDict = {}
for index,i in enumerate(test[:-1]):
    string = ""
    if test[index] == test[index+1]:
        string = i + test[index]
    else:
        break
    print string

推荐答案

一种方法是使用 itertools 中的 groupby :

One way is to use groupby from itertools:

from itertools import groupby
[''.join(g) for _, g in groupby(test)]
# ['AAA', 'T', 'GG']
