Leave some comments and. Types of Computer Programs . These programs help you play, work, learn and organize the details of your life, and they aren't limited to traditional desktop stations or laptops. Tablets, phones, cameras, automobiles and even home appliances have all been joined with computers to provide greater convenience and functionality. As a result, there are nearly as many types of computer programs as there are types of human activities. Productivity Software. Productivity applications comprise some of the most commonly used software programs in the world, especially in work settings. One of the reasons people use computers is to take advantage of the efficiencies of productivity software. The two most common types of productivity programs are word processors for typing and formatting documents, and spreadsheets for organizing and tabulating numerical data. Other productivity software includes slideshow applications for giving lectures and presentations, formula editors for writing mathematical equations, and media editing programs for making graphics, video and sound. Web Applications. The Internet is another reason people use computers, and a variety of computer programs facilitate different kinds of Internet use. Web browsers download and render HTML content into the Web pages that dominate the Internet. Email clients make possible the exchange of virtual correspondence. FTP clients enable the upload and download of files to a Web server - - a common part of maintaining a website. Know the Different Types of Graphic Designers 24,049 views. Share; Like; Download. None of that would exist if not for the impressionscreated by the designers using the programs on their computers. Based on over 1,000 votes from visitors like you. Place your vote on the list of Best Graphic Design Software Programs. In computer graphics, graphics software refers to a program or collection of. Different types of software are often designed to edit different types of graphics such as. Most graphics programs have the ability to. Free Graphics Software . It includes a raster image editor, supports all native Windows cursor types and Vista. A graphics program to create seamless 'tiles' which can be used e.g. Chat clients and messaging programs let people type, talk and videoconference with one another. Many programs, such as weather widgets and stock market tickers, have an online component that continuously updates the information on your computer. Games and Leisure. The video games industry has grown bigger than the motion picture industry, and many people play games on their computers, tablets and phones. Different video game genres include card and board games, story- oriented adventures, sports simulators, puzzle games, shooters and fighting games, action- oriented platforms, strategy games, mysteries, music games and massively multiplayer games. There are also nongame leisure programs, such as electronic book readers you use to read electronic books on your computer and media players that you use to watch movies or listen to music. Other Kinds of Programs. Other types of widely used computer programs include utility programs for organizing files and folders on your computer, file compression programs that shrink and segment files for faster online transfer, and security software like malware scanners and network firewalls. Some computer programs don't have a general use and instead serve a niche market. CorelDRAW Graphics Suite X8 includes all the tools to design graphics and layouts, edit photos and create web graphics and websites. Typography cannot always be neatly separated from the graphics of your Web site. Creating antialiased type. Sophisticated image editing programs such as Adobe Photoshop will create antialiased type. Composers use music notation programs to write music. Statistical computation programs help statisticians perform data analysis. Computer- assisted drafting programs assist architects with design structures. Webmasters use content management systems to efficiently organize and update the contents of their websites. Programmers use application programming interfaces to develop Internet media content. The rule of thumb is if you can think of something to do on a computer, someone has already written a computer program for it. Graphics — Hands- on Python Tutorial for Python 3. Graphics make programming more fun for many people. To fully. introduce graphics would involve many ideas that would be a. This section introduces a simplified graphics. John Zelle for use with his Python Programming. My slight elaboration of his package is graphics. Warning. It is particularly important in Microsoft Windows. Idle from the Start menu. There is an issue. A Graphics Introduction! It uses all sorts of. Python that are way beyond these tutorials. There is. no particular need to open graphics. Idle editor. Load into Idle and start running example graph. Intro. Steps. py. For the Python interpreter to find Zelle’s module, it. The first line above makes all the types of object of. Zelle’s module accessible, as if they were already defined like. Look around on your screen, and possibly underneath other windows. There should be a new window labeled “Graphics Window”, created. Bring it. to the top, and preferably drag it around to make it visible beside. Shell window. A Graph. Win is a type of object from Zelle’s. The assignment statement remembers the window object as. A pixel is the smallest little square that can by. Modern screen usually have more than 1. Press return: This creates a Point object and assigns it the name pt. A Point object. like each of the graphical objects that can be drawn on a. Graph. Win, has a method . Graphics windows. Cartesian (x,y) coordinate system. The dimensions are. The first coordinate is the. The second coordinate. The coordinate 5. We. will see later that we can reorient the coordinate system to fit. Henceforth you will see a draw method call after each object is created. Press return: cir=Circle(pt,2. The first line creates a Circle object with center at the. This object is. remembered with the name cir. As with all graphics objects that. Graph. Win, it is only made visible by. So far, everything has been drawn in the default color black. In this. case we use the previously named Point, pt, and specify another. Point directly. Technically the Line object is a segment between. Warning. In Python (1. Point. The points must be. Press return: rect=Rectangle(Point(2. In this simple system. Rectangle is restricted to have horizontal and vertical sides. Shortly this will be handy for. The parameters to the move method are the. See if you can guess the. Did you remember that the y coordinate increases down the. Take your last look at the Graphics Window, and make sure that all. Then destroy the window win with the. Graph.

Sample Graphics Programs. In Windows, have a directory. Python examples folder containing face. The whole program is shown first; smaller pieces of. A simple graphics example constructs a face from basic shapes.'''fromgraphicsimport*defmain(): win=Graph. Win('Face',2. 00,1. Up()# make right side up coordinates! Circle(Point(4. 0,1. Fill(. The second. Up method. All the lines of code up to. You will likely start your programs with similar. Circle(Point(4. 0,1. Fill('yellow')head. Circle(Point(3. 0,1. Fill('blue')eye. 1. The lines above create two circles, in each case specifying the. They are filled in and made visible. There are several ways an oval could be specified. This rectangle is. An advantage of. graphics is that you can see the results of your programming, and. The final action is to have the user signal to close the window. In a Graph. Win, that means using prompt must be made with. Text object displayed explicitly before the response is expected. Text(Point(win. get. Width()/2,2. 0),'Click anywhere to quit.')message. Mouse()win. close()The new addition to the Text parameters here is win. Width(). to obtain the window width. In this program, the. The win. close() is necessary. We will generally want to prompt the user to finally close the. The size and title on the window will. Something like the last line can be used to terminate. Warning. If you write a program with a bug. Graph. Win on the screen. Graph. Win lingers. Feel free to run. Idle. Note that the steps for the. The next example, triangle. In addition it explicitly interacts with the user. In Windows. you can double click on the icon for triangle. While running the program, follow the prompts in the graphics. After you have run the program, you can examine the program in Idle. Program: triangle. Windows)Interactive graphics program to draw a triangle,with prompts in a Text object and feedback via mouse clicks.'''fromgraphicsimport*defmain(): win=Graph. Win('Draw a Triangle',3.

A Windows Operating System Specialization: . It does describe. Windows graphical programs run with less clutter. If you ran the triangle. Windows, you might have noticed a console window first. For this program, there. In such cases. under Windows, you can change the source file extension from . If you are. using Windows, change the filename triangle. The distinction is irrelevant inside Idle, which always has its. Shell window. 2. 4. Event Driven Graphics. If you close a. graphics window that way, you are likely to get a Python error. On the other hand, if your program creates a graphics. In this case the close. This lack of robustness is tied to the simplification designed into. Modern graphics environments are.

Meanwhile you can look at. Then, under the. headings for specific types, only the specialized additional. The version for this Tutorial has a few elaborations. You are likely to need to adjust the positions of objects. Changing Scene Exercise. You may use the position of the mouse click to. Issues with Mutable Objects. Suppose you prefer to specify. You might come up with the following function. Rect, to return such a new Rectangle. Read the following. Rect(corner,width,height): '''Return a new Rectangle given one corner Point and the dimensions.'''corner. Rectangle(corner,corner. The second corner must be created to use in the Rectangle. Start corner. 2. from the given corner and shift it by the dimensions of the. Rectangle to the other corner. With both corners specified, you can. Zelle’s version of the Rectangle constructor. Unfortunately this is an incorrect argument. Run the example. program make. Rect. Bad. py: '''Program: make. Rect. Bad. py. Attempt a function make.

Rect(Point(2. Close(win. get. Width()/2,2. By stated design, this program should draw a rectangle with one. When you run it however that is. You should just see one Point. Hm, well the program did make the corners be the same. Recall we set. What happens after that? Read and follow the details of what happens. We need to take a much more careful look at what naming an object. A good way to visualize this association between a name and. The object here is a Point, which has an x.

The name corner is still associated with the same object. That is the problem: we. The solution is to use the clone method that is defined for all. It creates a separate. We just need to. change the lineto. A diagram of the situation after the cloning is: Though corner and corner. Then aftercorner. No conflict: corner and corner. Run the corrected example program, make. Rectangle. py. 2. More on Mutable and Immutable Types. We. had no such problems with the immutable types int or str. Read and follow the discussion of the following code. Just for comparison, consider the corresponding diagrams for code. After the first two lines we have an alias again: The third line does not change the int object 2. The result of the. Hence a is still associated with the integer 2 - no conflict. It is not technically correct to think of b as being the. With mutable types. Then it is very important to. Another mutable type is list. A list can be cloned with the.
