In this example, we can observe that, in an analogous way as it is done in the example of the if that was related to the area of a rectangle, two variables are initialized, h and b , these variables need that we enter the value of the height and base, then, these variables will be transformed to integers by means of the function int() .

Subsequently, and having the variables as integers, we proceed to enter into the conditional block and thus to calculate the required area. Firstly, we see the condition, in this case, has to be satisfied, so much that the number that relates to the base and the number that relates to the height, are positive, but simultaneously, as previously explained. If this condition is true, we proceed to calculate the area, we initialize a variable that has the value of the multiplication of the other two variables, and finally, we convert it into a string, so we can make the print().

Now in the case that the condition has not been satisfied, it will be shown in the screen a string that will say "Error", in order to make it clear that an error has happened in the program.

Finally, to finish the program, a print is made, which will inform us that the program has finished and that will print a "Bye" on the screen .

On the other hand, if we get to make the example of the division, this would be very similar to what we have just done, since the else would also make a print of "Error" and also the condition of the if , will be equal to what was done in that example, because what has to be met that the denominator will be different from zero.
