#1 Created at ... [Delete] [Delete and Lock User]

chang = input('chang:') kuan = input('kuan:') mianji = chang * kuan print('minaji =',mianji)

#2 Created at ... [Delete] [Delete and Lock User]

好吧，因为没定义变量，现在已经解决了

#3 Created at ... [Delete] [Delete and Lock User]

原来前面还要加个int。

chang=int(input('长:'))
kuan=int(input('宽:'))
print('面积=',chang*kuan)
