IF statements and Lists

[new_horizon]

Hi All,

A very basic (I'm sure) programming question, but I am creating a list of three mouse position clicks and if one of these clicks falls within a certain range, I would like to the program to execute some commands.

I'm sure this is very simple, but here is my code below...

yield viztask.waitTime(1.0) # wait before prompt
		yield viztask.waitAny( [ viztask.waitButtonDown(zone1button),viztask.waitButtonDown(zone2button),viztask.waitButtonDown(zone3button),viztask.waitButtonDown(zone4button),viztask.waitButtonDown(zone5button),viztask.waitButtonDown(nonebutton)]) 
		m_pos1 = viz.mouse.getPosition()
		yield viztask.waitAny( [ viztask.waitButtonDown(zone1button),viztask.waitButtonDown(zone2button),viztask.waitButtonDown(zone3button),viztask.waitButtonDown(zone4button),viztask.waitButtonDown(zone5button),viztask.waitButtonDown(nonebutton)]) 
		m_pos2 = viz.mouse.getPosition()
		yield viztask.waitAny( [ viztask.waitButtonDown(zone1button),viztask.waitButtonDown(zone2button),viztask.waitButtonDown(zone3button),viztask.waitButtonDown(zone4button),viztask.waitButtonDown(zone5button),viztask.waitButtonDown(nonebutton)]) 
		m_pos3 = viz.mouse.getPosition()
		m_pos = [m_pos1,m_pos1,m_pos3]
		grid.visible(viz.OFF)
		zone1button.visible(viz.OFF)
		zone2button.visible(viz.OFF)
		zone3button.visible(viz.OFF)
		zone4button.visible(viz.OFF)
		zone5button.visible(viz.OFF)
		nonebutton.visible(viz.OFF)
		if on_off == 1:
			stim=nv
			if m_pos > 0.4 and m_pos< 0.6:
				R = 1
				stim = 0
				prob_calc(R) # should be using last valid nv & R to calc next nv
				stop_calc()
			else:
				R = 0
				stim = 0
				prob_calc(R) # should be using last valid nv & R to calc next nv
				stop_calc()
		if on_off == 0:
			stim = 0
			nulltrials = nulltrials + 1
			if m_pos > 0.4 and m_pos < 0.6:
				falsep = falsep+1
			falserate = 100*falsep/nulltrials
		print 'Trial:',tr,'Reversals: ', reverse, 'False pos rate:', falserate, 'M_pos1', m_pos1,'M_pos2', m_pos2,'M_pos3', m_pos3
		print '--NEXT--'

Can anyone advise me?

Thanks
