Question

print "This is to find the area or perimeter of a rectangle "
print "Do you want to find the area(a) or perimeter(p) of your rectangle?"
a= raw_input(" I want to find the ")
if raw_input = (a)
        print "What is the length of the rectangle?"
        b = int(raw_input("The length of the rectangle is "))
        print "What is the width of the rectangle?"
        c = int(raw_input("The width of the rectangle is "))
        d = (2 * b) + (2 * c)
        print d
if raw_input = (p)
        print "Got it. What is the length of your rectangle?"
        x = int(raw_input("The length of the rectangle is ")) 
        print "What is the width of your rectangle?"
        y = int(raw_input("The width of the rectangle is "))
        z = x * y
        print z

如何编写代码来说明a是区域而p是周边？

这很奇怪，你无法检查是否raw_input()是什么。而且，测试相等性是==，=是要分配。这是你想要的：

print "This is to find the area or perimeter of a rectangle "
print "Do you want to find the area(a) or perimeter(p) of your rectangle?"
a= raw_input(" I want to find the ")
if a=='p':
        print "What is the length of the rectangle?"
        b = int(raw_input("The length of the rectangle is "))
        print "What is the width of the rectangle?"
        c = int(raw_input("THe width of the rectangle is "))
        d = (2 * b) + (2 * c)
        print d
elif a=='a':
        print "Got it. What is the length of your rectangle?"
        x = int(raw_input("The length of the rectangle is ")) 
        print "What is the width of your rectangle?"
        y = int(raw_input("The width of the rectangle is "))
        z = x * y
        print z

你的检查错了。在python中，=表示赋值，而==是对相等性的测试。试试这个：

print "This is to find the area or perimeter of a rectangle "
print "Do you want to find the area(a) or perimeter(p) of your rectangle?"
a= raw_input(" I want to find the ")
if a=='a':
    print "What is the length of the rectangle?"
    b = int(raw_input("The length of the rectangle is "))
    print "What is the width of the rectangle?"
    c = int(raw_input("THe width of the rectangle is "))
    d = b*c
    print d
elif a=='p':
    print "Got it. What is the length of your rectangle?"
    x = int(raw_input("The length of the rectangle is ")) 
    print "What is the width of your rectangle?"
    y = int(raw_input("The width of the rectangle is "))
    z = 2*x+2*y
    print z

如果要查找区域和周长的语句
