Step 3:Here we start adding logic for the clicks, and the simplest one to do is what should be the action performed by the calculator in Python when a user clicks “c”? A simple GUI app that takes in a price, a tax rate and calculates the final price. )How to load the Kivy language into python - 3 ways 3. Create a Calculator in Python Full Tutorial using Lambda's Function Join this channel to get access to codes, perks, and see more interesting videos. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Here we create individual functions to carry out the calculations and return the result. Remember the addButton() method we used to create each button? If you are holding a calculator in your hands right now, what we want to add is the “display” on which all of your operations are shown. These contain the various methods by which this code computes it's output. Improved GUI class code. All modern day gadgets have a calculator.You must have created a simple Python code to implement the basic Arithmetic operations in text form. Essentially what it does is it creates the button object we need with the value we need. More details will be discussed further. What we need to add is a command. Moreover, Tkinter is cross-platform, hence the same code works on macOS, Windows, and Linux. We will use Python 3.6, so if you are using Python 2.x, it’s strongly recommended to switch to Python 3.x unless you know the language changes so you can adjust the code to run without errors. Also user input is accepted along with the choice of operator. Creating a text-based calculator is a common exercise for beginners. Step 2:Define our first method __init__.This method is specific to python classes and acts as a constructor in object oriented concepts. I assume that you have a little background about Python basics to … from tkinter import * from tkinter import ttk. We are going to develop a Graphical User Interface version of calculator using Python3 and most famous GUI library tkinter. Does anyone help me? This basically assigns this method to the instance of the Calculator class. Also read: Python: Radio buttons in Tkinter The desired output of this article will guide you through the process of creating a GUI calculator in Python that will look like this: The following I see as “must haves” for this app: Throughout this we will be working with tkinter, which is the standard GUI library for Python. In this section we will work on adding our created buttons to the GUI. Let’s create a GUI based simple calculator using Python Tkinter module, which can perform basic arithmatic operations addition, subtraction, multiplication and division. Since Tkinter is cross-platform so it works on both windows and Linux. Python offers a lot of options to develop GUI applications, but Tkinter is the most usable module for developing GUI(Graphical User Interface). This is exactly what we do here.– Then we delete the current text from the equation line using .delete() method of a tkinter Entry class (similar to how we cleared the line when user clicked “c”).– And finally insert our answer into the equation line using .insert() method of a tkinter Entry class. My professor … Let’s go through all of the code together with explanations. My calculator does what he asked and I am within the the line limit (Maximum of 300 lines if you were curious. Feel free to leave comments below if you have any questions or have suggestions for some edits. Whereas now you want to develop a GUI (graphic user interface) for such a program so it’s more presentable and easily reusable. I am missing a few other buttons, and I do plan to add them later on. This is because we still need to implement the actual application logic in our Python code. As an example, if you currently have “1+” in your equation line and then click “1”, what we do is glue together “1+” and “1” to get “1+1” and paste in back into the equation line. tkinter is Python’s de facto standard GUI and is … After the previous step we have a completely designed GUI for our calculator app. Tutorial on building a desktop calculator in python. Simple Tax Calculator — Skeleton UI. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. So we have created this method to create buttons. )Writing python code that will work with the calculator GUI 4. This creates rectangular areas of the screen to organize the widgets to python application. For example, b9 is a button for 9, b_add is a button for addition, and so on.Now, the question that comes up is: what is this self.addButton()? For the purposes of explaining the details I hard coded them one by one. The Tkinter toolkit helps create the perfect GUI for a simple calculator and the available variety of functions and the vast scope of being able to orient and organize the GUI makes it very easy and convenient to have an elegant and useful calculator out of a little code on your computer. edit Okay, so far we have our calculator main screen and the equation display attached to it. Within the Calc() class, you have your functions (denoted by def etc.). 2. Step 1:We need to create some equation line that we want to add to our Calculator class, hence we define it as self.equation and then use a tkinter class Entry() to create a widget.There are a few arguments that go into the Entry() class. With 4 lines of code you already made a command-line calculator in Python, now let’s use the same concept to build a calculator with a graphical interface. All we want to do in that case is to add it to our equation line.– First, we delete the existing text in the equation line .delete() method of a tkinter Entry class.– Then we concatenate the current_equation with value (which is the recent click) and insert it into the equation line using .insert() method of a tkinter Entry class. To begin with, your interview preparations Enhance your Data Structures concepts with the Python DS Course. Tkinter widgets used for creating the calculator GUI. from tkinter import * class Calculator: def __init__(self, master): self.master = master master.title("Python Calculator") # create screen widget self.screen … This may look like a difficult to understand code, but we will discuss in detail what each part does, so bare with me. If you’d like to learn more about wxPython, then check out How to Build a Hooking up the logic. Here is a Calculator_GUI() class. Simple Calculator in Python with GUI A calculator is used to do mathematical calculations. This part is very intuitive and requires us to add only two lines of code to our __init__ method: The reason we are adding it to the __init__ method is because we want this to be “created” as soon as the application starts. Making these additions to our code, you should arrive at the following: Copy paste the above code into your editor and run it. My calculator does what he asked and I am within the the line limit (Maximum of 300 lines if you were curious. Since our equation line takes up the whole width of the screen, it means that it takes place of exactly 4 columns. Step 6:Specify what should happen when we execute the file.This is quite sequential, so follow the logic.– We first create a local variable root and assign Tk() to it. A graphical user interface is an application that has buttons, windows, and lots of other elements that the user can use to interact with your application. The class Calc() contains all the functions for this piece of code. Notepad & Calculator In Tkinter + Why Tkinter? Step 2:We create a Button class with a few parameters that we need:–self.master: this assigns the Button object to the Calculator class.–text=value: this will display the “value” we passed as an argument as text on the button.–width=9: this is just styling, and you can adjust the width of the buttons. We would want the equation line cleared if a user clicks “c”, and this is exactly what we do by using .delete() method of the equation line which is a tkinter Entry class. As the next step what we would like to do is add an equation line to our calculator GUI. I invite you to have a read into the "official" Style Guide for Python Code - section "Documentation Strings" (or this for further reading). For example, if your current_equation is “1+1” and is a string, if you run 1+1 in Python, it will give you 2 as output. Write the code that I provided below into the text editor. Tkinter is builtin the Python module for developing the GUI application. First Python GUI Calculator with exponentiation function and percents. After that a new window will appear containing a black file this will be the text editor for the python. Contribute to SoumyaMukhija/calculator development by creating an account on GitHub.
