如何删除字符串中由/*和*/表示的注释？

def remove_comments(string):
    start_index = string.find("/*")
    end_index = string.find("*/")
    
    while start_index != -1 and end_index != -1:
        string = string[:start_index] + string[end_index + 2:]
        start_index = string.find("/*")
        end_index = string.find("*/")
    
    return string

# 示例用法
string_with_comments = "This is a /* multiline */ string with /* comments */."
string_without_comments = remove_comments(string_with_comments)
print(string_without_comments)
