Yield multiple values

Question

Can\'t we yield more than one value in the python generator functions?

Example,

In [677]: def gen():
   .....:     for i in range(5):
   .....:         y         


        

Answer 1

Your function gen returns a generator and not values as you might expect judging from the example you gave. If you iterate over the generator the pairs of values will be yielded:

In [2]: def gen():
   ...:     for i in range(5):
   ...:         yield i, i+1
   ...:         

In [3]: for k1, k2 in gen():
   ...:     print k1, k2
   ...:     
0 1
1 2
2 3
3 4
4 5
