Week 7 Libraries and More Python/16. Sort by the difference of goals

@@ -0,0 +1,150 @@
+'''
+Write a function
+
+sortby_goalsdiff(teams: list)
+
+which takes as parameter a list of tuples. A single tuple represents the team's result for the current season. The first element of the tuple is the team name (string). The second element is also a string: it represents the goals scored and conceded by the team during the season. So an example of a tuple could be
+
+("TPS", "201 - 51")
+
+The goal difference is calculated by subtracting the goals conceded by the team from the goals scored. In this example, the goal difference would be 150 (i.e. 201 - 51). 
+
+Your task is to arrange the list in ascending order according to the goal difference between the teams: the team with the worst (i.e. lowest) goal difference comes first in the list and the best team comes last.
+
+Note! You can either use a lambda statement or write your own value function. This does not affect the scoring.
