Description:
 def pick_up_tip(self, location: Union[types.Location, Well] = None, presses: int = 3, increment: float = 1.0) -> 'InstrumentContext': """ Pick up a tip for the pipette to run liquid-handling commands with If no location is passed, the Pipette will pick up the next available tip in its :py:attr:`InstrumentContext.tip_racks` list. The tip to pick up can be manually specified with the `location` argument. The `location` argument can be specified in several ways: * If the only thing to specify is which well from which to pick up a tip, `location` can be a :py:class:`.Well`. For instance, if you have a tip rack in a variable called `tiprack`, you can pick up a specific tip from it with ``instr.pick_up_tip(tiprack.wells()[0])``. This style of call can be used to make the robot pick up a tip from a tip rack that was not specified when creating the :py:class:`.InstrumentContext`. * If the position to move to in the well needs to be specified, for instance to tell the robot to run its pick up tip routine starting closer to or farther from the top of the tip, `location` can be a :py:class:`.types.Location`; for instance, you can call ``instr.pick_up_tip(tiprack.wells()[0].top())``. :param location: The location from which to pick up a tip. :type location: :py:class:`.types.Location` or :py:class:`.Well` to pick up a tip from. :param presses: The number of times to lower and then raise the pipette when picking up a tip, to ensure a good seal (0 [zero] will result in the pipette hovering over the tip but not picking it up--generally not desireable, but could be used for dry-run). :type presses: int :param increment: The additional distance to travel on each successive press (e.g.: if `presses=3` and `increment=1.0`, then the first press will travel down into the tip by 3.5mm, the second by 4.5mm, and the third by 5.5mm). :type increment: float :returns: This instance """
