Question

Consider I have the two following tuples:

keys=("second", "minute", "hour", "day")
values=(1, 60, 60, 24)

I would like to create a dictionary that has the keys tuple as keys and the values tuple as values. Here’s my naive way of doing it:

d={}
for i in xrange(len(keys)):
    d[keys[i]] = values[i]

Is there an easier more elegant way of doing this?

I work primarily with Python2.7, so I would prefer the answers to privilege this version.

The zip function turns a pair of iterables into a list of pairs. The dict constructor accepts a number of forms of arguments, one of which is a sequence of (key, value) pairs. Put the two together, and you get just what you want:

dict(zip(keys, values))
