为什么输入的sanwich_orders列表里面有6个元素,后面finish_sanwiches打印出来的只有3个元素。
sanwich_orders = ['pastrami','egg','tuna','pastrami','cucumber','pastrami']
finish_sanwiches = []
print(sanwich_orders)
for orders in sanwich_orders:
print("I made your "+ orders +" sanwich. ")
order = sanwich_orders.pop()
finish_sanwiches.append(order)
print(finish_sanwiches)
for finish_sanwich in finish_sanwiches:
print(finish_sanwich.title()+" sanwich is okay. ")
她的输出记过是图片那样的。
