Few alternative solutions (other are possible), I usually use a variant
of the first version, inside a partition function, the second variant
is shorter when you don't have a handy partition() function and you
don't want to import modules, and the forth one needs less memory when
the data is very long:
from itertools import izip, islice
data = [1,2,3,4,5,6,7]
for x1, x2 in (data[i:i+2] for i in xrange(0, len(data)/2*2, 2)):
print x1, x2
for x1, x2 in zip(data[::2], data[1::2]):
print x1, x2
for x1, x2 in izip(data[::2], data[1::2]):
print x1, x2
for x1, x2 in izip(islice(data,0,None,2), islice(data,1,None,2)):
print x1, x2
