The vim plugin cannot modify python comment format

I have comment like this:
```
#the class of Game Field, draw the game field,
#operation of moving(upward, downward, left, right) or merge, add new number for each step
#evaluate the situation (if the player win or lose)
```
With autopep8, spaces should be added after the comment sign '#', and the second comment line is so long that it should be wrapped. However, with yapf, I see no changes to the comment lines. Do you have similar features about this?
