POSubtracting by Dictionary Values from Iterated Total in For Loop Python
text
Body
copied!<p>Working in Python 2.7.</p> <p>I have a dictionary with team names as the keys and the values are contained in lists. The first value is the amount of runs the team scored, the second is runs allowed:</p> <pre><code>NL = {'Phillies': [662, 476], 'Braves': [610, 550], 'Mets': [656, 687]} </code></pre> <p>I have a function that iterates over each key and provides the total runs scored and allowed for the dictionary as a whole. I would also like to be able to subtract each individual team from the total, and create a league minus team value.</p> <p>I first tried something along the lines of this:</p> <pre><code>def Tlog5(league, league_code): total_runs_scored = 0 total_runs_allowed = 0 for team, scores in league.iteritems(): total_runs_scored += float(scores[0]) total_runs_allowed += float(scores[1]) team_removed_runs = total_runs_scored - scores[0] </code></pre> <p>Unfortunately, that appeared to be subtracting from only the values that had already been iterated instead of the complete total. So, for the first team in the dictionary, team_removed_runs was 0, for the second team it was the the total runs for of the first two teams minus the second teams total (leaving only the first teams total.</p> <p>I tried to move the team_removed_runs = total_runs_scored - scores[0] out of the for loop, but then I only got a value for the last team in the dictionary.</p> <p>Is there a way I can return the team_removed runs for all the teams in the dictionary?</p> <p>Thanks for any help!</p>
