如何将字符串中间的字符替换为随机字符？

import random

def replace_middle_chars(string):
    # 确定要替换的字符串
    middle_chars = string[1:-1]

    # 生成随机字符
    random_char = chr(random.randint(33, 126))  # ASCII码范围为33-126

    # 将随机字符替换到字符串中间的字符位置
    replaced_string = string[0] + random_char * len(middle_chars) + string[-1]

    return replaced_string

# 示例用法
original_string = "Hello World"
replaced_string = replace_middle_chars(original_string)
print(replaced_string)
