Sorting dictionaries is a common occurrence during project writing, and it only takes a few lines of code to implement multi-conditional sorting. This fully demonstrates the benefits of python.
teamitems = [{'team':'France' , 'P':1 , 'GD':-3 , 'GS':1 , 'GA':4},
{'team':'Uruguay' , 'P':7 , 'GD':4 , 'GS':4 , 'GA':0},
{'team':'SouthAfrica' , 'P':4 , 'GD':-2 , 'GS':3 , 'GA':5},
{'team':'Mexico' , 'P':4 , 'GD':1 , 'GS':3 , 'GA':2}]
print sorted(teamitems ,key = lambda x:(x['P'],x['GD'],x['GS'],x['GA']),reverse=True)
The above code is sorted by 'P',' GD',' GS','GA', and reverse=True means descending order
Of course not bad
from operator import itemgetter
print sorted(teamitems ,key = itemgetter('P','GD','GS','GA'),reverse=True)
