Note that the code you posted does not call onclick(). Globals are confusing
IMHO. Code becomes cleaner and easier to write and read when you become
familiar with classes.
import turtle
class TurtleTest():
def __init__(self):
self.ctr=0
t = turtle.Turtle()
s = turtle.Screen()
s.onclick(self.clicked)
turtle.mainloop()
def clicked(self, x, y):
print self.ctr
if 0 == self.ctr:
self.first()
elif 1 == self.ctr:
self.second()
elif 2 == self.ctr:
self.third()
self.ctr += 1
def first(self):
print "first called"
def second(self):
print "second called"
def third(self):
print "third called"
TT = TurtleTest()
