如何对字符串中包含int值和字符串值字符串进行划分

import re

def split_string(string):
    # 使用正则表达式进行匹配划分
    ints = re.findall(r'\d+', string)
    strings = re.findall(r'\D+', string)
    return ints, strings

def split_string_loop(string):
    # 使用循环遍历字符串进行划分
    ints = ""
    strings = ""
    for char in string:
        if char.isdigit():
            ints += char
        else:
            strings += char
    return ints, strings

def split_string_functions(string):
    # 使用字符串处理函数进行划分
    ints = ""
    strings = ""
    for char in string:
        if char.isdigit():
            ints += char
        else:
            strings += char
    return ints, strings

# 测试示例
string = "abc123def456"
ints, strings = split_string(string)
print("使用正则表达式进行匹配划分：")
print("数字部分：", ints)
print("字符串部分：", strings)

ints, strings = split_string_loop(string)
print("使用循环遍历字符串进行划分：")
print("数字部分：", ints)
print("字符串部分：", strings)

ints, strings = split_string_functions(string)
print("使用字符串处理函数进行划分：")
print("数字部分：", ints)
print("字符串部分：", strings)
