Fix Python – List of tuples to dictionary [duplicate]


Asked By – Sarah Vessels

Here’s how I’m currently converting a list of tuples to dictionary in Python:

l = [('a',1),('b',2)]
h = {}
[h.update({k:v}) for k,v in l]
> [None, None]
> {'a': 1, 'b': 2}

Is there a better way? It seems like there should be a one-liner to do this.

Now we will see solution for issue: List of tuples to dictionary [duplicate]


Just call dict() on the list of tuples directly

>>> my_list = [('a', 1), ('b', 2)]
>>> dict(my_list)
{'a': 1, 'b': 2}
