Exercise $1-2$

Use IDLE to run programs

This exercise guides you through the process of using IDLE to compile and run three programs:

Run the console version of the Future Value program

Start IDLE and open the future$\_$value.py file that should be in this folder: murach$/$python$/$book$\_$apps$/$ch$01$

Press F$5$ to compile and run the program. Then, enter values for monthly investment, yearly interest rate, and years when you're prompted for them. This should display the future value that's calculated from your entries.

When you're asked if you want to continue, enter $"y"$ if you want to do another calculation or $"n"$ to exit the program. Then, close the IDLE window for the source code.

Run the GUI version of the Future Value program

$4.$ Open the future$\_$value$\_$gui.py file that should be in the same folder as the future$\_$value.py file.

$5.$ Select Run $$ Run Module to compile and run the program. Then, enter values for the first three text boxes, and click the Calculate button to view the future value that's calculated from your entries.

$6.$ If you want to do another calculation, enter new values and click the Calculate button. When you're through, click the Exit button to exit the program. Then, close the IDLE window for the source code.

Run the Guess the Number program of chapter $4$

$7.$ Open the guess$\_$the$\_$number.py file that's in this folder: murach$/$python$/$book$\_$apps$/$ch$04$

$8.$ Compile and run the program. Then, guess the number. This demonstrates the type of program that you'll be able to write by the time you complete chapter $4.$

$9.$ Close the window for the source code.
