python 2.7 - Why Does it say "Bad Input"? -

print "this find area or perimeter of rectangle or triangle?" print "do want find area or perimeter of rectangle(r) or triangle(t)?" l= raw_input("i want find area or perimeter of ") if l=='r':     print "do want find area(a) or perimeter(p) of rectangle?"     a= raw_input(" want find ")     if a=='p':         print "what length of rectangle?"         b = int(raw_input("the length of rectangle "))         print "what width of rectangle?"         c = int(raw_input("the width of rectangle "))         d = (2 * b) + (2 * c)         print d     elif a=='a':         print "got it. length of rectangle?"         x = int(raw_input("the length of rectangle "))          print "what width of rectangle?"         y = int(raw_input("the width of rectangle "))         z = x * y         print z if l=='t':     print "do want find area(a) or perimeter(p) of triangle?"     m= raw_input("i want find "     if m == 'a':         print "what length of triangle?"         n = int(raw_input("the length of triangle "         print "what width of triangle?         o = int(raw_input("the width of triagle "         q = (n * o)/2         print q     elif m=='p'         print "what first length of triangle?"         r = int(raw_input("the first length of triangle ")         print "what second length of triangle?"         s = int(raw_input("the second length of triangle ")         print "what third length of triangle?"         u = int(raw_input(" third length of triangle ")         v = r + s + u         print v 

it says bad input on line stating if m=='a'. please help.

you have a lot of missing brackets ). must check match. every ( must have corresponding ).

also, have : missing, after if or elif conditions:

fixed:

print "this find area or perimeter of rectangle or triangle?" print "do want find area or perimeter of rectangle(r) or triangle(t)?" l = raw_input("i want find area or perimeter of ") if l == 'r':     print "do want find area(a) or perimeter(p) of rectangle?"     = raw_input(" want find ")     if == 'p':         print "what length of rectangle?"         b = int(raw_input("the length of rectangle "))         print "what width of rectangle?"         c = int(raw_input("the width of rectangle "))         d = (2 * b) + (2 * c)         print d     elif == 'a':         print "got it. length of rectangle?"         x = int(raw_input("the length of rectangle "))         print "what width of rectangle?"         y = int(raw_input("the width of rectangle "))         z = x * y         print z if l == 't':     print "do want find area(a) or perimeter(p) of triangle?"     m = raw_input("i want find ")     if m == 'a':         print "what length of triangle?"         n = int(raw_input("the length of triangle "))         print "what width of triangle?"         o = int(raw_input("the width of triagle "))         q = (n * o) / 2         print q     elif m == 'p':         print "what first length of triangle?"         r = int(raw_input("the first length of triangle "))         print "what second length of triangle?"         s = int(raw_input("the second length of triangle "))         print "what third length of triangle?"         u = int(raw_input(" third length of triangle "))         v = r + s + u         print v
