What I need is for it to print "the sum of 1 and 2 is 3". I'm not sure how to add a and b because I either get an error or it says "the sum of a and b is sum".
def sumDescription (a,b):
sum = a + b
return "the sum of" + a " and" + b + "is" sum
You cannot concat ints to a string, use str.format and just pass in the parameters a,b and use a+b to get the sum:
def sumDescription (a,b):
return "the sum of {} and {} is {}".format(a,b, a+b)
sum is also a builtin function so best to avoid using it as a variable name.
If you were going to concatenate, you would need to cast to str:
def sumDescription (a,b):
sm = a + b
return "the sum of " + str(a) + " and " + str(b) + " is " + str(sm)
Use string interpolation, like this. Python will internally convert the numbers to strings.
def sumDescription(a,b):
s = a + b
d = "the sum of %s and %s is %s" % (a,b,s)
sumDescription(1.5, 4) -> the sum of 1 and 4 is 5
%f would give different output too, str.format just makes life simplerYou are trying to concatenate string and int.
You must turn that int to string before hand.
def sumDescription (a,b):
sum = a + b
return "the sum of " + str(a) + " and " + str(b) + " is " + str(sum)
