> 9. Create dict from keys and values using zip

In 2.7+, I'd recommend a dictionary comprehension instead.

In this case,

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

edit:

As I mention below, this becomes useful when you want to do e.g.

    {f(k): g(v) for k, v in zip(keys, values)}

I'd disagree, as

  dict(zip(keys, value))

is more concise, doesn't introduce extra variables, and doesn't repeat itself, and explicitly names a dict rather than using a symbol.

Right, but the second you need to modify either the key or the value, you are better off with the dict comprehension. It's like map() vs [...].

I like list comprehensions and to me dict comprehensions feel like a natural extension of this. It means that you can do things like

    {k.upper(): v ** 2 for k, v in zip(keys, values)}

Or generally

    {f(k): g(v) for k, v in zip(keys, values)}

I find this very extensible. In terms of conciseness, they both fit on a single line and I like the whitespace inside a dict comprehension.
