Go to the Utilities folder on your Mac and run Terminal. It will look something like this. Last login Mon Jan 1. Welcome to Darwin Now type python and press the return button. Your screen should look like this now. Python 2. 3. 5 1, Jan 1. GCC 4. 0. 1 Apple Computer, Inc. Type help, copyright, credits or license for more information. The means that python is waiting for you to program something. Keeping a Secret. Python can remember things, so lets tell it to remember our secret word. You can tell it to print something by saying print. Python will remember the secret until you quit. So you can always go back and print your. Now try to print something python doesnt know. Traceback most recent call last. File, line 1, in. Name. Error name number is not defined. Dont worry. This is fine. You can just teach python what number is and try again. Computers are Good Calculators. Your computer is better than any calculator at doing math. Lets try some. print 23. In Python, plus and minus are normal but times and divide. Some other symbols to know. What will it do when we say lenstr1. Try your own fancy formulas. Dont worry if you get errors. Picking a Random Number. Python comes with libraries of functions that do almost anything. Lets tell Python to pick a random number. Get the random library by typing this. Now we can say random. Which number did you get You can learn about libraries by saying help. Try typing this. helprandom. Help on module random. Random variable generators. It will show lots of information, and you can press the space bar. Eventually you will see a long. We dont have time to read it all now, so you can press q. You can use help to ask about most things in python. Words and Numbers. What do you think happens when you try to do math with wordsTraceback most recent call last. File, line 1, in. Type. Error cannot concatenate str and int objects. If you add two words, it sticks them together. If. you times a word by 3, it makes three copies. Python doesnt know how to add a word and a number. A word that you put in quotes is just a string of letters. Numbers that dont have a decimal. You cant add a str and an int. But you can turn a number into a string if you use the str function. Using for to Repeat. You can repeat something with the for command. If you say for something in something with. Try this. for letter in secret. Think about your program it is saying for every letter. The computer repeats print letter nine. If it didnt work for you, dont worry. Press return and try again. Check that you put in the extra spaces and the punctuation. Spaces at the beginning of a line do make a difference in python. Of course, in our game we shouldnt give away our secret word. So once you have the hang of it, try this. The comma at the end of print tells it not to start a new line. Making Your Own Program. A program is just a file with code in it. Lets make one. Start Text. Edit from your Applications folder. Go to the Format menu and say Make Plain Text. Now type this in. The Smiths The Queen Is Dead Zip Software Programs. The first line tells the computer which what language the. After that, you can write as many lines of python code as you like. Save the file with the name game. Unattend.Xml The Specified File Does Not Exist. Running Your Program. Go back to Terminal. If you are still in python. D to get out. Arrange your windows. Text. Edit and Terminal at the same time. The magic way to make a file into a program is. Desktopgame. py. The chmod command stands for change mode and x means. You just marked. your file as a program. Now you can run your program by typing its name. Desktopgame. py. Thats it. Youve made your first program Programs are just Scripts. A program is just a script that a computer reads. If we put a lot of lines of. Try typing these extra lines into your Text. Edit. Dont forget to save the file again. Now run the program in Terminal. You can use the up arrow if you dont want to bother. After you have. the name of your program, press return. Desktopgame. py. See what happens Everthing in your program ran very. Using if to Choose. In our hangman game, we should show where. To decide whether to print a line or a letter. Try changing your program inside Text. Edit like this. usrbinenv python. Dont forget to line everything up, and remember to save it. What happens when you run it The line ifsomething in something makes. If the letter is in our guesses, it prints the letter. Otherwise it prints a little line. Since the whole thing is under the. Desktopgame. py. Check your spelling and spacing and punctuation if. Take your time to get it to work. Input with rawinputOur game is no good if you cant guess. To let the player. It works like this. So try changing your program to look like this. The guesses guess line add the guess to the string of guesses. If the string of guesses was aeiou and the new guess is c, then. Desktopgame. py. You can guess any letter and it will show it to you. Using while to Repeat. We need to let the player take more than one turn. The while command can repeat our. You need to indent everything under the while command. So you will need to add some spaces. Lets also move the guessing after the. The command turns 1 means subtract one from turns,. Then the next time. When turns is finally. Try running your program. Does it work Improving Our Game. We can already play our game. Now we need to fix it up so that it is fun. The player should win right away when there are no missing letters. The player should only lose a turn on a wrong guess. When the player loses, the game should tell the secret. Here is one way to improve it. You win. guess rawinputguess a letter. Nope. print turns, more turns. The answer is, secret. The missed number counts how many blanks we are. Automate the Boring Stuff with Python. Controlling the Keyboard and Mouse with GUI Automation. Knowing various Python modules for editing spreadsheets, downloading files, and launching programs is useful, but sometimes there just arent any modules for the applications you need to work with. The ultimate tools for automating tasks on your computer are programs you write that directly control the keyboard and mouse. These programs can control other applications by sending them virtual keystrokes and mouse clicks, justpython. This technique is known as graphical user interface automation, or GUI automation for short. With GUI automation, your programs can do anything that a human user sitting at the computer can do, except spill coffee on the keyboard. Think of GUI automation as programming a robotic arm. You can program the robotic arm to type at your keyboard and move your mouse for you. Virginia Woolf Una Stanza Tutta Per Se Ebook. This technique is particularly useful for tasks that involve a lot of mindless clicking or filling out of forms. The pyautogui module has functions for simulating mouse movements, button clicks, and scrolling the mouse wheel. This chapter covers only a subset of Py. Auto. GUIs features you can find the full documentation at http pyautogui. Installing the pyautogui Module. The pyautogui module can send virtual keypresses and mouse clicks to Windows, OS X, and Linux. Depending on which operating system youre using, you may have to install some other modules called dependencies before you can install Py. Auto. GUI. On Windows, there are no other modules to install. On OS X, run sudo pip. Quartz, sudo pip. On Linux, run sudo pip. Scrot is a screenshot program that Py. Auto. GUI uses. After these dependencies are installed, run pip install pyautogui or pip. OS X and Linux to install Py. Auto. GUI. Appendix A has complete information on installing third party modules. To test whether Py. Auto. GUI has been installed correctly, run import pyautogui from the interactive shell and check for any error messages. Before you jump in to a GUI automation, you should know how to escape problems that may arise. Python can move your mouse and type keystrokes at an incredible speed. In fact, it might be too fast for other programs to keep up with. Also, if something goes wrong but your program keeps moving the mouse around, it will be hard to tell what exactly the program is doing or how to recover from the problem. Like the enchanted brooms from Disneys The Sorcerers Apprentice, which kept fillingand then overfillingMickeys tub with water, your program could get out of control even though its following your instructions perfectly. Stopping the program can be difficult if the mouse is moving around on its own, preventing you from clicking the IDLE window to close it. Fortunately, there are several ways to prevent or recover from GUI automation problems. Shutting Down Everything by Logging Out. Perhaps the simplest way to stop an out of control GUI automation program is to log out, which will shut down all running programs. On Windows and Linux, the logout hotkey is CTRL ALT DEL. On OS X, it is SHIFT OPTION Q. By logging out, youll lose any unsaved work, but at least you wont have to wait for a full reboot of the computer. You can tell your script to wait after every function call, giving you a short window to take control of the mouse and keyboard if something goes wrong. To do this, set the pyautogui. PAUSE variable to the number of seconds you want it to pause. For example, after setting pyautogui. PAUSE 1. 5, every Py. Auto. GUI function call will wait one and a half seconds after performing its action. Non Py. Auto. GUI instructions will not have this pause. Py. Auto. GUI also has a fail safe feature. Moving the mouse cursor to the upper left corner of the screen will cause Py. Auto. GUI to raise the pyautogui. Fail. Safe. Exception exception. Your program can either handle this exception with try and except statements or let the exception crash your program. Either way, the fail safe feature will stop the program if you quickly move the mouse as far up and left as you can. You can disable this feature by setting pyautogui. FAILSAFE False. Enter the following into the interactive shell import pyautogui. PAUSE 1. pyautogui. FAILSAFE True. Here we import pyautogui and set pyautogui. PAUSE to 1 for a one second pause after each function call. We set pyautogui. FAILSAFE to True to enable the fail safe feature. Controlling Mouse Movement. In this section, youll learn how to move the mouse and track its position on the screen using Py. Auto. GUI, but first you need to understand how Py. Auto. GUI works with coordinates. The mouse functions of Py. Auto. GUI use x and y coordinates. Figure 1. 8 1 shows the coordinate system for the computer screen its similar to the coordinate system used for images, discussed in Chapter 1. The origin, where x and y are both zero, is at the upper left corner of the screen. The x coordinates increase going to the right, and the y coordinates increase going down. All coordinates are positive integers there are no negative coordinates. Figure 1. 8 1.  The coordinates of a computer screen with 1. Your resolution is how many pixels wide and tall your screen is. If your screens resolution is set to 1. The pyautogui. size function returns a two integer tuple of the screens width and height in pixels. Enter the following into the interactive shell import pyautogui. You can store the width and height from pyautogui. Now that you understand screen coordinates, lets move the mouse. The pyautogui. move. To function will instantly move the mouse cursor to a specified position on the screen. Integer values for the x and y coordinates make up the functions first and second arguments, respectively. An optional duration integer or float keyword argument specifies the number of seconds it should take to move the mouse to the destination. If you leave it out, the default is 0 for instantaneous movement. All of the duration keyword arguments in Py. Auto. GUI functions are optional. Enter the following into the interactive shell import pyautogui. To1. 00, 1. 00, duration0. To2. 00, 1. 00, duration0. To2. 00, 2. 00, duration0. To1. 00, 2. 00, duration0. This example moves the mouse cursor clockwise in a square pattern among the four coordinates provided a total of ten times. Each movement takes a quarter of a second, as specified by the duration0.
