Python: some practice, questions and #%§'

[jkor]

I seem to have some success with the following snippet in PPL:

Code:


#PYTHON EXPORT mktest()
from hpprime import *
from math import *

# haven't found terminal screen clear yet
print("""Perform one of the following:
1. position mouse pointer on screen and then double-touch
2. click a calculator key
3. press 'On' to exit""")
lastm,lastk=0,0
while 1:
  # gets 2nd pair of coords (2-touch)
  # move mouse ptr around screen and double touch
  m=mouse()[1]
  k=keyboard()
  if len(m)>0 and m!=lastm:
    print('2-touch y= '+str(m[1]))
  if k>0 and k!=lastk:
    print('key= '+str(int(log2(k))))
  lastm=m
  lastk=k
#end

The snippet prints the y-coord of the mouse pointer for a two-point touch, or the key code for a clicked calculator key and can be exited by pressing 'On'. Both mouse() and keyboard() don't seem to accept any parameters.

As noted in one of your previous posts, I haven't had any luck making a Python script file work (using the More>Files>New Program feature of the Editor).

Thanks for your invaluable contributions to the knowledge base. Your posted have been very helpful in trying to figure things out.
