>>> x =input("x:") x:34 >>> y =input("y:") y:42 >>> print x * y SyntaxError:invalid syntax哪里错了啊
>>> x =input("x:") x:34 >>> y =input("y:") y:42 >>> print x * y SyntaxError:invalid syntax
哪里错了啊
>>> x =input("x:") x:34 >>> y =input("y:") y:42 >>> print x * y SyntaxError:invalid syntax哪里错了啊
这里因为你的python版本应该是3以上,3以上你获取的x,y是str,2.7是int,所以你要int(x)*int(y),

>>> x =input("x:")

>>> y =input("y:")
y:42
>>> x
'34'
>>> y
'42'
>>> int(x)
34
>>> int(y)
42
>>> int(x) * int(y)

>>> print(int(x) * int(y))
