def seek(self, percent, precise=True):
'''Change the position to a percentage of duration.
:Parameters:
`percent`: float or int
Position to seek, must be between 0-1.
`precise`: bool, defaults to True
Precise seeking is slower, but seeks to exact requested
percent.
.. warning::
Calling seek() before the video is loaded has no effect.
.. versionadded:: 1.2.0
.. versionchanged:: 1.10.1
The `precise` keyword argument has been added.
