我的程序几乎完成了,但我似乎不能允许。。。你知道吗
“你想多做些计算吗?输入(Y)表示“是”,或输入任何“”其他字符表示“否”
…通过多次输入我的选择(例如“Y”或任何其他字符)而输出。你知道吗
我真的很感激你的帮助!你知道吗

如果这真的是你的第一个节目,那真是令人印象深刻!你知道吗
因此,我粘贴了下面我们要关注的代码:
在第一行,计算机提示输入“你想做更多的计算吗?”(以此类推)。然后将第一个输入存储在变量
restart_msg
中。然后,在第二行中,调用restart(str(input(restart_msg)))
。因为它包含对input()
的调用并将restart_msg
作为唯一的参数传递,所以计算机通过输出您刚才输入的内容来提示输入。它将该条目存储在字符串中,并将其传递给restart()
。你知道吗似乎这是你在第二行的意图:
这样,计算机通过
str()
将您输入的第一个输入转换为字符串,并通过重新启动函数将其传递给您。你知道吗这是一个雄心勃勃的项目,祝你好运!你知道吗
你在请求一个输入的输入。restart\u msg=input(),然后执行输入(restart\u msg)。你知道吗
另外请注意,没有必要使用str()将输入转换为字符串,因为python3 input()中已经返回了一个字符串。你知道吗
