我的程序几乎完成了，但我似乎不允许...
"您想做更多的计算吗？要输入（y），或任何"否"字符。
...从不先进入我的选择（例如" y"或任何其他字符"）的输出多次。
输出
我真的很感谢您的帮助！

如果这确实是您的第一个程序，那确实令人印象深刻！
所以，我已经粘贴了要关注下面的代码：
restart_msg = input("Would you like to do more calculations? Enter (Y) for yes, or any other character for no. ")
if not restart(str(input(restart_msg))): # uses the function I wrote
return # Stop the program
在第一行中，计算机提示输入"您想做更多计算？"（等等）。然后，它将该首先输入存储在变量restart_msg中。然后，在第二行中，您致电restart(str(input(restart_msg)))。由于其中包含对input()的调用并将restart_msg作为唯一参数传递，因此计算机通过输出刚输入的任何内容来提示输入。它将该条目存储在字符串中，并将其传递给restart()。
看来这是您在第二行中的意图：
if not restart(str(restart_msg)):
这样，计算机通过通过str()传递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。
这是一个非常雄心勃勃的项目，祝你好运！
您要求输入输入。restart_msg = input（），然后您进行输入（restart_msg）。
还要注意，无需像python3 Input（）中的str（）将输入转换为字符串。
