Sometimes, we want to sort a list by multiple attributes with Python.
In this article, we’ll look at how to sort a list by multiple attributes with Python.
How to sort a list by multiple attributes with Python?
To sort a list by multiple attributes with Python, we can use the sorted function with the operator.itemgetter method.
For instance, we write:
import operator
l = [[12, 'tall', 'blue', 1], [2, 'short', 'red', 9], [4, 'tall', 'blue', 13]]
s = sorted(l, key=operator.itemgetter(1, 2))
print(s)
We have the l nested list that we want to sort by the 2nd and 3rd items in each nested list.
Then we call sorted with l and the key set to operator.itemgetter called with 1 and 2 to sort l and return the sorted list.
We then assign the returned list to s.
Therefore, s is [[2, 'short', 'red', 9], [12, 'tall', 'blue', 1], [4, 'tall', 'blue', 13]].
Conclusion
To sort a list by multiple attributes with Python, we can use the sorted function with the operator.itemgetter method.
