split array of arrays into single elements (gambling game project)

I am trying to generate a list of all possible outcomes of a football/soccer match that I will then pass into another function. However, my program creates a list of 10 lists (each containing two elements) instead of one long list. Thus, it will not loop through in the coming function.

I am unable to use .split() because there was nothing I could use as a proper splitting character.

Does anyone know how I can either break up "test_scores" or how to generate a single, 100 object list, from the beginning?

Thank you so much.

import numpy as np

team1= np.array(list(range(10)))
team2=np.array(list(range(10)))

#arrays for all possible game outcomes in range ten between team 1 and 2
scores=[[[x,y] for x in team1] for y in team2]
test_scores = scores
print(test_scores)

>Solution :

So close! Just delete two characters:

scores=[[x,y] for x in team1 for y in team2]
