[Matplotlib-users] removing upper and right ticks

[per f. <per...@gm...>]

hi all,

i have the following plot:

rcParams['xtick.direction'] = 'out'
rcParams['ytick.direction'] = 'out'
scatter(x, y)

this changes the tick directions to be out. how can i make it so only the
ticks on the x axis and y axis appear? i.e. remove the ticks that are in the
top axis (the one parallel to the x-axis) and in the right most axis (the
one parallel to the y-axis)?

thanks.
