Python拆分字符串而不拆分转义字符 [英] Python split string without splitting escaped character

问题描述

有没有办法在不拆分转义字符的情况下拆分字符串?例如，我有一个字符串，想按 ':' 而不是按 '\:'

Is there a way to split a string without splitting escaped character? For example, I have a string and want to split by ':' and not by '\:'

http\://www.example.url:ftp\://www.example.url

结果应该如下:

['http\://www.example.url' , 'ftp\://www.example.url']

推荐答案

注意 : 似乎不是需要转义的字符.

Note that : doesn't appear to be a character that needs escaping.

我能想到的最简单的方法是在字符上拆分，然后在转义时将其添加回来.

The simplest way that I can think of to accomplish this is to split on the character, and then add it back in when it is escaped.

示例代码(非常需要一些整理.):

Sample code (In much need of some neatening.):

def splitNoEscapes(string, char):
    sections = string.split(char)
    sections = [i + (char if i[-1] == "\\" else "") for i in sections]
    result = ["" for i in sections]
    j = 0
    for s in sections:
        result[j] += s
        j += (1 if s[-1] != char else 0)
    return [i for i in result if i != ""]
