Demographics. What are DemographicsDemographics is the study of a population based on factors such as age, race and sex, among others. Governments, corporations and non government organizations use demographics to learn more about a populations characteristics for many purposes, including policy development and economic market research. For example, a company that sells high end RVs wants to know roughly how many people are at or nearing retirement age and what percentage are able to afford the product. BREAKING DOWN Demographics. Demographics is the collection of data regarding a specific population. It is frequently used as a business marketing tool to determine the best way to reach customers and assess their behavior. Segmenting a population by using demographics allows companies to determine the size of a potential market. The use of demographics helps to determine whether its products and services are being targeted to that companys most important consumers. Market segments may identify a particular age group, such as Baby Boomers born from 1. Millennials born 1. C tutorialLearn C programming language GUI a simple caculator.

The common variables that are gathered in demographic research include age, sex, income level, race, employment, location, home ownership and level of education. Demographics make certain generalizations about groups in order to identify customers. Additional demographic factors include gathering data on preferences, hobbies, lifestyle and more. Governmental agencies collect data when conducting a national census and may use that demographic data to forecast economic patterns and population growth in order to better manage resources.

Most large companies conduct demographic research in order to determine how to market their product or service and best capture the target audience. It is valuable to know the current customer and where the potential customer may come from in the future. Demographic trends are also important, since the size of different demographic groups changes over time as a result of economic, cultural and political circumstances. This information helps the company decide how much capital to allocate to production and advertising. For example, the aging U. Calculator Program In GuitarsCalculator Program In GuinnessS. Each market segment can be analyzed for its consumer spending patterns. Older demographic groups spend more on health care products and pharmaceuticals, and the method of communicating with this customer differs from that of their younger counterpart. Your first GUI app with Python and Py. Qt Python For Engineers. Introduction. Many people struggle with learning how to build a GUI app. The most common reason is, they dont even know where to start. Most tutorials are purely text based, and its hard to learn GUI development using text, since GUIs are mainly a visual medium. We will get around that by building a simple GUI app, and show you how easy it is to get started. Once you understand the basics, its easy to add advanced stuff. This is what we will be building A simple GUI app that takes in a price, a tax rate and calculates the final price. Most tutorials on GUI apps try to layout the GUI blocks using code, but that is very painful to do. We will be using the superb QT Designer tool to layout our app So no struggling laying out the design by hand. Everything will be done graphically.

All the source code is here. Pre requisites. If you followed my advice and installed Anaconda, you will already have Py. Qt. 4. If not, you will need to get it from here. You also need Qt Designer. Update As Steve points out in the comments, Anaconda comes with qt designer, so you dont need to download anything It is in Anaconda. Librarybin and is called designer qt. Untitled11.png' alt='Calculator Program In Guise' title='Calculator Program In Guise' />I recommend you download the whole QT suite, as there are some other useful tools in there too. Getting Started. Note You can click on any image below to see the full size, in case you want more detail. Start QT Designer. In the window that comes up, choose Main Window, as it will give is a blank canvas The next thing to do is to select the Text Edit box on the left Drag Text Edit to the main window, to get a box like See the right side, where I have clumsily red circled a box That is where the name of the object is. The name is the way this object will be called from our Python code, so call it something sensible. Im calling it pricebox, as we will enter the price into this box. The next thing we will do is attach a label to the box, to make it clear to the user what this box is for. Above, I have circled the label. Drag it across to the main window. It gets the default text of Text. Label. Double click it and change it to Price. You can also make the text large and bold, as seen here For the tax box, we are going to use something different. See the spin box The circle on the left is a spin box. This limits the values you can enter. We dont need a spinbox, its just good to see how you can use different widgets that QT Creator provides. Drag the spin box to the window. The first thing we do is change the object. Name to something sensible, taxrate in our case. Remember, this is how this object will be called from Python. We can choose a default value for our spinbox. Im choosing 2. 0 If you look at the image above, you can also set the minimum and maximum limits. We will keep them to what they are. We will also add another label called Tax Rate, same as we did before. Also look at the circled Push Button we will be using next Now, select the Push Button box and drag it to our window. The button just says Push. Button, which isnt very helpful. By now, you should know how to change this. But before that, we change the name of the button and not the text to calctaxbutton. Next,  we change the actual text Drag another Text Edit box on to the window. You dont need to label it, as we will print the output in here. Do change its name to resultswindow not shown below, but you should know how to do it by now. If you want, you can add a header. This is a simple label box with the font increased And save your work This file will be used in the next part when we write the code, so store it somewhere you can access it. This file that we  created is just a XML file. Open it in a text editor, if you want, and you will find something like this Writing the code. Qts code is object oriented, and in  a manner that is easy to follow. Each of the widgets we added is an object, with its own functions like to. Plain. Text to read the value in a box. This makes it quite easy to use. Im sure the official documentation mentions this somewhere, but you have to do some setup before you can use the code. I couldnt find this setup anywhere, so I worked back from the official examples as well as other online tutorials to find the smallest program you need to initialize the class. I have checked this function in as pyqtskeleton. This is useful, as everytime you start a new Py. Qt project, use this skeleton to start off, and add your code. The code is. from Py. Qt. 4 import Qt.

Excel Electrical Cable Selection Calculator Software. Just use the skeleton and work on that. Take this file, pyqtskeleton. Thats because we dont want to edit the original file. The first thing to do is add our XML file, the one that contains our GUI, to the code. Replace this line. Creator. File Enter file here. Creator. File Enter file here. Creator. File taxcalc. Creator. File  taxcalc. This will load our GUI file into memory. Now, the key widget in our GUI was the button. Once you press the button, something happens. What We need to tell our code what to do when the user presses the Calculate Tax button. In the init function, add this line. Calculate. Tax1self. Calculate. TaxWhat does this doRemember we called our button calctaxbutton This was the name of the object, not the text that was displayed on it. All QT widgets have specific functions, which you can find our by Googling. The last part of the code says connectself. Calculate. Tax. This says that connect this button to a function called self. Calculate. Tax, so that everytime the user presses this button, that function is called.
