Create a dictionary with list comprehension in Python?

Question

I like the Python list comprehension syntax.Can it be used to create dictionaries too? For example, by iterating over pairs of keys and values: mydict = {(k,v) for (k,v) in blah blah blah} # doesn't work

Answer 1

Yes, Python has dictionary comprehensions. You almost have the syntax correct. If you have two sequences, one of keys, and one of values, this will work:

myDict = {k:v for (k,v) in zip(keys, values)}
