替换范围文本，然后插入符号

import re

def replace_and_insert(text, start_pattern, end_pattern, replacement, insert_symbol, insert_position):
    # 使用正则表达式查找匹配的文本
    match = re.search(start_pattern + '(.+?)' + end_pattern, text)
    if match:
        # 获取匹配的文本
        matched_text = match.group(1)
        # 替换匹配的文本
        replaced_text = text.replace(matched_text, replacement)
        # 在指定位置插入符号
        insert_index = match.start(1) + len(replacement)
        final_text = replaced_text[:insert_index] + insert_symbol + replaced_text[insert_index:]
        return final_text
    else:
        return text

# 示例用法
text = "Hello [world]!"
start_pattern = r'\['
end_pattern = r'\]'
replacement = "universe"
insert_symbol = '*'
insert_position = 5

result = replace_and_insert(text, start_pattern, end-pattern, replacement, insert_symbol, insert_position)
print(result)  # 输出: Hello *universe!
