Sample Solution:-

Python Code:

from heapq import nlargest
from operator import itemgetter
items = {'item1': 45.50, 'item2':35, 'item3': 41.30, 'item4':55, 'item5': 24}

Python: Convert byte to a string?

You need to decode the bytes object to produce a string:

>>> b"abcde"
b'abcde'

# utf-8 is used here because it is a very common encoding, but you
# need to use the encoding your data is actually in.
>>> b"abcde".decode("utf-8") 
'abcde'
