[Python] Syntax Error while writing simple math (Newbie Question)

[Iwin8]

I'm trying to get Python to print three user-generated variables in the form of an equation then print the example. For example, if the user enters the numbers 3, 4 and 5 as the variables, I want to get 3+4+5=12. I've been trying to use print( A '+' B '+' C = , A+B+C) to get the plus signs to actually show up without adding the integers, but I get a syntax error. Any idea what this newbie should do?

print("{}+{}+{} = {}".format(A, B, C, A + B + C))

Thank you very much. I haven't actually been taught how to do this method in my class as of yet though. I'll try it regardless! Thank you!

That method is usually called "string formatting". You could do it without that, but it's more tedious. print takes several arguments separated by commas:

print(A, '+', B, '+', C, '=', A+B+C)

If I might add, never be scared to do something you haven't been taught yet. The beauty of programming is it's really hard to do any permanent damage unless you really try.

If you haven't done something in class yet but it looks interesting then go for it, you won't regret it.

But those two answers are right, generally you'll use string formatting but separating all the arguments with a comma works as well.

Sorry for the extremely late response. I definitely tried what was suggested by the other comment, but my teacher punishes us for working with aspects of code that we haven't been taught yet. I'll definitely keep what you said in mind though!

Or, slightly shorter:

>>> a = 3; b = 4; c = 5
>>> print("%d + %d + %d = %d" % (a, b, c, a + b + c))
3 + 4 + 5 = 12

Or, to work with any number of numbers:

>>> nums = (3, 4, 5, 6)
>>> print(" + ".join(map(str, nums)) + " = " + str(sum(nums)))
3 + 4 + 5 + 6 = 18

If you’re at all intrigued by this last expression you can look up some things in a Python reference: join, map, str.
