Question

所以当我尝试调用我的customer_name（）时，函数会一直调用我的while循环。似乎总是调用我的phone_number，然后循环进入customer_name循环。然后，如果我在循环播放时接受phone_number，则调用pizza_menu的while循环。我已经尝试过多次解决这个问题，但没有运气，有人能帮助我吗？此外，我尝试将所有变量customer_name，phone_number等添加到最后打印出来但它一直给我“未定义”我想将它们全部添加到列表中然后在最后打印出来。我希望有人可以帮助我，我真的很感激。我不被允许上课，因为我们还没有学到这一点。使用python 3.3

premium_pizzas = ["Supreme Cheese", "The Legendary pizza", "Pentakill supreme", "Teeto shroomo supreme", "The volcanic rengar", "Cheese and Ham" , "Vegetriano" ]

这是因为你的缩进不一致，你的电话号码循环不在一个函数中，所以一旦脚本运行就会立即运行。

我的while循环被调用而不是我的函数
