class random var write to array

[ThomasL]

I tried to refactor your code in a way it makes sense from what i assume to understand you want to do.
Look and learn.

import numpy as np
 
class Data:
    
    def __init__(self, x, y, r, g, b):
        self.x = x
        self.y = y
        self.r = r
        self.g = g
        self.b = b
        # or to make in some way possible what you want to do
        self.data = {'x':x, 'y':y, 'R':r, 'G':g, 'B':b}
    
def randomi():
    return [np.random.randint(0, 100) for i in range(5)]
    

def main():
    arr = np.zeros((5), dtype='int64')
    print(arr)
    
    x, y, r, g, b = randomi()
    print(x, y, r, g, b)
    
    p = Data(x, y, r, g, b)
    
    for i, character in enumerate('xyRGB'):
        arr[i] = p.data[character]
        print(character, arr[i])
    
    print(arr)

    
if __name__ == "__main__":
    main()
