Ah, well. Don't know whether it meets your aesthetic standards, but:
*>>my_list = ['tree', 'hug', 'flower', 'hug', 'bear', 'run']
*>>my_list[0:len(a):2]
['tree', 'flower', 'bear']
*>>my_list[1:len(a):2]
['hug', 'hug', 'run']

and hence

*>>zip(my_list[0:len(a):2], my_list[1:len(a):2])
[('tree', 'hug'), ('flower', 'hug'), ('bear', 'run')]

and furthermore

*>>for a, b in zip(my_list[0:len(a):2], my_list[1:len(a):2]):
... * * print a, b
...
tree hug
flower hug
bear run

or the slightly less obfuscated:

*>>for index in range(0, len(my_list), 2):
... * * print my_list[index], my_list[index + 1]
... * *
tree hug
flower hug
bear run

[snip]
I don't know what the "len(a)" is, but the end position defaults to
the end:

>>zip(my_list[0::2], my_list[1::2])

[('tree', 'hug'), ('flower', 'hug'), ('bear', 'run')]
