SyntaxError: Missing parentheses in call to 'print'

执行demo中的

length=5
breadth=2
area=length*breadth
print 'Area is',area
print 'Perimeter is',2*(length+breadth)

报错

File "expression.py", line 7
    print 'Area is', area
                  ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('Area is', area)?

查询发现是demo代码python版本是2

本地python是3

print 是print('Area is', area)才对、

改为：

print ('Area is', area)
print 'Perimeter is',2*(length+breadth)

后，执行成功
