s = '12;;7.osjd ;.jshdjdknx ' where; . is the separator

What are the solutions?

How to split a string using different delimiters

Method 1: Through the str.split() method, process one separator at a time

#!/usr/bin/python3
 
 
def go_split(s, symbol):
    result = [s]
    for i in symbol:
        median = []
        # 普通方法
        # for x in result:
        #     median.extend(x.split(i)
         
        # 列表解析
        # [median.extend(y.split(i)) for y in result if y]
         
        # map高阶函数,map生成可迭代对象
        for z in map(lambda x: x.split(i), result):
            median.extend(z)
     
        # 以上三个方法都可以解决问题
        result = median
         
    # 去除空字符串
    return [x for x in result if x]
 
if __name__ == "__main__":
    # 定义初始字符串
    s = '12;;7.osjd;.jshdjdknx+'
    # 定义分隔符
    symbol = ';./+'
     
    result = go_split(s, symbol)
    print(result)

Method 2: Through the re.split() method, Split all strings at once, recommended

#!/usr/bin/python3
 
import re
 
 
def go_split(s, symbol):
    # 拼接正则表达式
    symbol = "[" + symbol + "]+"
    # 一次性分割字符串
    result = re.split(symbol, s)
    # 去除空字符
    return [x for x in result if x]
 
 
if __name__ == "__main__":
    # 定义初始字符串
    s = '12;;7.osjd;.jshdjdknx+'
    # 定义分隔符
    symbol = ';./+'
     
    result = go_split(s, symbol)
    print(result)
