python - error printing Integer with strings -


i beginner python trying write not working. help?

cp=input("enter cost price: ") sp=input("enter sale price: ") if (sp>cp):     print ("congratulations !! made profit of ", + sp-cp)      print("congratulations!! made profit of %f" % sp-cp) elif (cp>sp):     print("you in loss of %f" % cp-sp) else:     print("you got nothing")

in python 3 (which i'm assuming using because of python-3.x tag included), input function returns string, , can't math on string. need change

cp=input("enter cost price: ") sp=input("enter sale price: ")

to

cp = int( input("enter cost price: ") ) sp = int( input("enter sale price: ") )

(spaces added show changed).

as answer above said, need add parenthesis around substitution values 

print("congratulations!! made profit of %f" % sp-cp)

becomes

print("congratulations!! made profit of %f" % (sp-cp) )

(edit: benjamin beat me 3 seconds!)
