Create pandas DataFrame from two lists with same keys

Question

I have two lists of tuples with the same keys as shown below. How can I create a pandas DataFrame with the key as the index and the values in columns?

l1 = [('jan', 1.2), ('feb', 1.3), ('mar', 1.1)]
l2 = [('jan', 1.1), ('feb', 1.2), ('mar', 1.3)]

Answer 1

df = pd.DataFrame([dict(l1), dict(l2)]).transpose()
