How to enumerate a range of numbers starting at 1
...port the start parameter so instead you could create two range objects and zip them:
r = xrange(2000, 2005)
r2 = xrange(1, len(r) + 1)
h = zip(r2, r)
print h
Result:
[(1, 2000), (2, 2001), (3, 2002), (4, 2003), (5, 2004)]
If you want to create a generator instead of a list then you can use iz...

append multiple values for one key in a dictionary [duplicate]
...values into a list of tuples. To do this, you can use list slicing and the zip function.
data_in = [2010,2,2009,4,1989,8,2009,7]
data_pairs = zip(data_in[::2],data_in[1::2])
Zip takes an arbitrary number of lists, in this case the even and odd entries of data_in, and puts them together into a tup...

Mapping over values in a python dictionary
...
+1: this is what I would do too. dict(zip(a, map(f, a.values()))) is marginally shorter, but I have to think about what it's doing, and remind myself that yes, keys and values are iterated over in the same order if the dict doesn't change. I don't have to think ...
