将字符串分成3列:文本、数字、文本

^([a-zA-Z]+)(\d+)([a-zA-Z]+)$

import re

def split_string(string):
    pattern = r'^([a-zA-Z]+)(\d+)([a-zA-Z]+)$'
    match = re.match(pattern, string)
    if match:
        text1 = match.group(1)
        number = match.group(2)
        text2 = match.group(3)
        return text1, number, text2
    else:
        return None

# 示例用法
string = "abc123def"
result = split_string(string)
if result:
    text1, number, text2 = result
    print("文本1:", text1)
    print("数字:", number)
    print("文本2:", text2)
else:
    print("字符串格式不符合要求")

文本1: abc
数字: 123
文本2: def
