I also think it's unfortunate that zip silently discards items. Almost
always when I use zip I would prefer to see an error when the two
iterables are not of the same length. Of course you're not necessarily
safer with len and range:
a = [1, 2, 3]
b = 'abcde'
for n in range(len(a)):
print(a[n], b[n])
