从字符串中提取名称和编号

^(.*)-(\d+)$

import re

def extract_name_and_number(string):
    pattern = r'^(.*)-(\d+)$'
    match = re.match(pattern, string)
    if match:
        name = match.group(1)
        number = match.group(2)
        return name, number
    else:
        return None

# 示例用法
string = "产品A-12345"
result = extract_name_and_number(string)
if result:
    name, number = result
    print("名称:", name)
    print("编号:", number)
else:
    print("无法提取名称和编号")

        number = parts[1]
        return name, number
