Need a little help, (rock, paper, scissors program)

Question

I started making (rather figuring out) a rock, paper, scissors program (based off on another guy's example) and I have the issue of when I run the program and I type in:

Rock, paper or scissors: rock
Rock, paper or scissors: paper

I should get:
You: -1

, but I always get:
You: 1

whatever I change in the program itself (at least changes that I've tried).

I would gadly hear suggestions on how to solve this problem and tips (maybe) as to how I could continue and upgrade on the program itself.

Thank you all in advance.

Here's the program:

def game(a,b):
human=a
comp=b
points=0
a=str(input("Rock, paper or scissors: "))
b=str(input("Rock, paper or scissors: "))
if human=="rock" and comp=="paper":
human=points-1
print("You: "+str(human))
elif human=="rock" and comp=="scissors":
human=points+1
print("You: "+str(human))
elif human=="paper" and comp=="rock":
human=points+1
print("You: "+str(human))
elif human=="scissors" and comp=="rock":
human=points-1
print("You: "+str(human))

elif human=="paper" and comp=="scissors":
human=points-1
print("You: "+str(human))

elif human=="scissors" and comp=="paper":
human=points+1
print("You: "+str(human))
elif human!="rock" and human!="paper" and human!="scissors":
print("wrong choice, try again")

elif comp!="rock" and comp!="paper" and comp!="scissors":
print("network error")

game("scissors","paper")

Answer 1

Nice, it works. Much appriciated.
But by the way what was the problem?
The only thing I see you've changed was leaving out the unnecessary variables, or was that the problem somehow?

Answer 2

When you called your function with the variables emplaced, you were asking for a result of
Human => scissors
Comp => paper

You could also remove your input requests from within the def, and place them in the final line.

Game(input(), input())

Answer 3

Oh I get it, originally that part was in the example where I took it from. Didn't really know at the moment what its porpuse was, but I get it now.

Thanks✌
