How to Sort a Dictionary by Values

Assume that we have the following dictionary and we want to sort it by values (assume that the values are numeric data type).

d={"a":3,"b":5,"c":2}

# sort it by value
dict(sorted(d.items(), key=lambda item: item[1]))

{'c': 2, 'a': 3, 'b': 5}

If we want to sort it in descending order:

dict(sorted(d.items(), key=lambda item: item[1], reverse=True))

{'b': 5, 'a': 3, 'c': 2}

Finally, if we want to get the first n keys:

n = 2
dict(sorted(d.items(), key=lambda item: item[1])[0:n])

{'c': 2, 'a': 3}
