Assistance with missing required positional arguments

Question

def computeValue(condition , gps , wifi , camera):
    int(val1=0)
    int(val2=0)

    val1 = (condition + gps + wifi + camera)
    val2 = (condition + gps + wifi + camera)
    return val1
    return val2

def main():

    w=0;
    x=0;
    y=0;
    z=0;
    q=0;
    r=0;
    s=0;
    t=0;
# it then has conditions to assign values to wxyzqrst, and then

    val1 = computeValue(w+x+y+z)
    val2 = computeValue(q+r+s+t)
main()

error: TypeError: computeValue() missing 3 required positional arguments: 'gps', 'wifi', and 'camera'

Anyone have any idea as to what Im doing wrong?

Answer 1

Yu;

wwii, is right - a tutorial would do you great service as this is pretty foundational to programming so you are going to have a long road to travel if you don't take some time and learn the fundamentals.

However, in general, think of a function (computeValue in your case), as a mathematical algorithm. Imagine instead it was to compute the area of a rectangle. You would say Area = F(x,y) = x * y. From this you could say F(1,2)=2, F(2,2) = 4, F(4,3)= 12, and so on. But you couldn't say F(3*4) - that wouldn't make sense as it would mean the same as F(12). Your algorithm definition requires two arguments, not one.

Now - extend that to your computeValue function. You define it as requiring 4 arguments (aka parameters). However, you are trying to call it using "w+x+y+z". Python is going to be smart enough to add those values before calling the function. Much like F(12) above, you are only giving a single argument (or parameter). You need for values separated by a comma, such as computeValue(w,x,y,z)

Thats problem #1. Your next problem is that you can't return twice from a function (val1 and val2). You can return a list, array, tuple, etc. from a function and use each part but I think that will complicate things beyond what you are ready for at this point. For now, if you want two different calculations, just make two functions.
