boundary=--------------------------197275785202230528605557帮我写个python程序生成boundary

以下是生成boundary的Python程序示例：

import random
import string

BOUNDARY_LENGTH = 30

def generate_boundary():
    """生成随机的boundary"""
    boundary = ''.join(random.sample(string.ascii_letters + string.digits, BOUNDARY_LENGTH))
    return '--------------------------{}'.format(boundary)

# 调用函数生成boundary
boundary = generate_boundary()
print(boundary)

运行结果：
