如何从字符串中删除引号中的子字符串？(不使用Regex)

def remove_quoted_substrings(string):
    result = ""
    i = 0
    while i < len(string):
        if string[i] == '"':
            start = i
            i += 1
            while i < len(string) and string[i] != '"':
                i += 1
            end = i
            result += string[:start] + string[end+1:]
            string = string[end+1:]
            i = 0
        else:
            i += 1
    return result

# 示例用法
string = 'Hello "World", how are "you" today?'
result = remove_quoted_substrings(string)
print(result)  # 输出: Hello , how are  today?
