Question

1.) Sort movies based on the rating of the movie (key: 'rating') from highest to lowest. This time, break ties with the value of 'no_of_votes' (if two movies have the same rating, the one with more votes should come first)

movies = [{ "name" : "Inception", "rating" : 9, "no_of_votes": 10000},
{ "name" : "Tamasha", "rating" : 8, "no_of_votes" : 1000 },
{ "name" : "Dark Knight Rises" , "rating" : 9, "no_of_votes": 10200 }]

2.) Define a function smallest that accepts a list of integer and returns the smallest integer in the list passed to it. Implement smallest using one line of code. This should be done with a lambda function.

For example, smallest([4221, 5464, 34345, 45458]) should be 4221

Answer 1

#1
#method to sort list of movies based on rating and votes
def Sort(ml):
for i in range(len(ml)):
s=False
for j in range(0,len(ml)-i-1):
if ml[j+1]['rating']>ml[j]['rating']:
ml[j],ml[j+1]=ml[j+1],ml[j]
s=True
elif ml[j+1]['rating']==ml[j]['rating']:
if ml[j+1]['no_of_votes']>ml[j]['no_of_votes']:
ml[j],ml[j+1]=ml[j+1],ml[j]
s=True
if s==False:
break
#2
def Min():
return lambda a : min(a)
smallest =Min()
#testing above methods
movies = [{ "name" : "Inception", "rating" : 9, "no_of_votes": 10000},
{ "name" : "Tamasha", "rating" : 8, "no_of_votes" : 1000 },
{ "name" : "Dark Knight Rises" , "rating" : 9, "no_of_votes": 10200 }]
Sort(movies)
print(movies)
a=smallest([4221, 5464, 34345, 45458])
print(a)
