python - How to convert list of key-value tuples into dictionary?

Question

I have a list that looks like:

[('A', 1), ('B', 2), ('C', 3)]

I want to turn it into a dictionary that looks like:

{'A': 1, 'B': 2, 'C': 3}

What's the best way to go about this?

EDIT: My list of tuples is actually more like:

[(A, 12937012397), (BERA, 2034927830), (CE, 2349057340)]

I am getting the error ValueError: dictionary update sequence element #0 has length 1916; 2 is required

Answer 1

>>> dict([('A', 1), ('B', 2), ('C', 3)])
{'A': 1, 'C': 3, 'B': 2}
