problems with unpacking returned values in tuples-CodePudding

I have a function that gets arguments of the file, this function looks for the coordinates of this file on the screen and then returns them. I know that this question could be very stupid but please help.

redx,redy = somefunc(Ui_Ellements[9], 12)

def somefunc(file,index):
    .....
    x=int((pt[0]*2 w)/2)
    y=int((pt[1]*2 h)/2)
    print("Found " file,x,y)
    if index==12:
        return (x,y)

All should be working correctly, but I have such a problem

redx,redy = somefunc(Ui_Ellements[9], 12) TypeError: cannot unpack non-iterable int object

I tried:
1.

def move(index):
    print(index)
    for i in index:
        print(i)
red = somefunc(Ui_Ellements[9], 12)
move(red)

def somefunc(file,index):
    .....
    x=int((pt[0]*2 w)/2)
    y=int((pt[1]*2 h)/2)
    print("Found " file,x,y)
    if index==12:
        return (x,y)

red = somefunc(Ui_Ellements[9], 12)
print(red[0])

red = somefunc(Ui_Ellements[9], 12)
print(red[-1])

P.s all data is correct and if I try

print(red)

it outputs data

CodePudding user response：

You need keep a function has basically same type of output in most of common situation.

you can replace return 0 to return 0,0
or you can replace it to raise Exception(f"Not found {file}")

I don't know what you exactly want to return when you return True, you can also replace it with same style, such as raise Exception(f"can't get redx and redy").

example:

def test(x,y):
    index = x   y
    if index == 12:
        return (x,y)
    else:
        raise Exception("Not found file")
        # return 0,0
try:
    a,b = test(2,3)
    print(a,b)
except Exception as e:
    print(e)

try:
    a,b = test(7,5)
    print(a,b)
except Exception as e:
    print(e)

result:

Not found file
7 5
