Practice with generators

Write a generator function odds_up_to(n) that uses yield to generate odds from 1 up to n, inclusive (if n is odd).

Here’s a sample interaction:

>>> for x in odds_up_to(5): print(x)
...
1
3
5
>>> for x in odds_up_to(1): print(x)
...
1
>>> for x in odds_up_to(2): print(x)
...
