1.3. PYTHON CALCULATOR Page 11Figure 1.10: Executing the HelloWorld.py Script and Console WindowSo, if we want to calculate the vertical position for an initial velocity v 0 = 5m/s after 0,6 seconds, wecan calculate the y(t = 0, 6) with one simple Python call.>>> print 5*0.6 -0.5*9.81*0.6**21.2342>>>A second version of the calculation can be performed introducing and using variables as follows. So wecan check every Python command within the Interactive Window.>>> v0 = 5>>> g = 9.81>>> t = 0.6>>> y = v0*t - 0.5*g*t**2>>> print y1.2342>>>A third version of our calculation of the ball’s height could be a Python script, which we can load andexecuted within the PythonWin IDE. To comment the code we insert some comments, which starts withthe # character. Characters at the right side of the # character are ignored by the Python interpreter.First small Example# program for computing the height of a ball thrown up in the airv0 = 5# initial velocityg = 9.81# acceleration of gravityt = 0.6# timey = v0*t - 0.5*g*t**2 # vertical positionprint y# printing the resultEnd of Coding2.12.2011
