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

Use yield from

def gen():
    for i in range(5):
        yield from (i, i+1)

[v for v in gen()]
# [0, 1, 1, 2, 2, 3, 3, 4, 4, 5]

The python docs say:

When yield from is used, it treats the supplied expression as a subiterator.
