Our football team finished the championship.
The result of each match look like "x:y". Results of all matches are recorded in the collection.
For example:
```["3:1", "2:2", "0:1", ...]```
Write a function that takes such collection and counts the points of our team in the championship.
Rules for counting points for each match:
- if x>y - 3 points
- if x<y - 0 point
- if x=y - 1 point
Notes:
- there are 10 matches in the championship
- 0 <= x <= 4
- 0 <= y <= 4
def points(games):
    return sum(3 if x > y else 0 if x < y else 1 for x, y in (score.split(":") for score in games))
def points(games):
    return sum(3 if x > y else 0 if x < y else 1 for x, y in (score.split(":") for score in games))
