How to find the 1st, 2nd, 3rd highest values in a list in Python

Question

I know how to find the 1st highest value but don\'t know the rest. Keep in mind i need to print the position of the 1st 2nd and 3rd highest value.Thank You and try to keep it si

Answer 1

This will print a list of the 3 highest items, each paired with its index:

lst = [9,7,43,2,4,7,8,5,4]
print( sorted( [(x,i) for (i,x) in enumerate(lst)], reverse=True )[:3] )

Things are a bit more complicated if the same value can appear multiple times (this will show the highest position for a value):

lst = [9,7,43,2,4,7,8,5,4]
ranks = sorted( [(x,i) for (i,x) in enumerate(lst)], reverse=True )
values = []
posns = []
for x,i in ranks:
    if x not in values:
        values.append( x )
        posns.append( i )
        if len(values) == 3:
            break
print zip( values, posns )
