Python Project - 2 (Simple Calculator)

Idea and Need:

Every one of us uses default calculator on PC (yeah, it's a great one...), but as a programmer, we are the one who spends most of the time on CMD or terminal (for MAC once). So why not create a simple calculator which can be used on CMD and yes, it feels so good when you use your own programs to complete daily stuff.So let's see what steps you should follow...

Steps:

  1. We have to create a menu which has the option to select which operation to perform.
  2. You can add as many operations as you want, but I am taking following basic one:
    1. Addition
    2. Subtraction
    3. Multiplication
    4. Division(remember about 0...😎)
    5. Power
    6. Square Root
    7. Natural Log
    8. Log to base 10
    9. Factorial
  3. Show user that what are you doing...for example if it is the addition of 2 and 3, print 2 + 3 = 5 on screen.
  4. After performing any operation ask the user if he/she again want to use the calculator. If yes, run calculator again otherwise exit the program.
  5. Take help of google, stack overflow wherever needed instead of looking my code. 
  6. It is a very easy application, so try to complete it in a minimum time as possible.
  7. Create functions wherever possible, so that your code will look neat and clean.

Modules required:

  • math

What you will learn:

    • Basic loops and menu driven program
    • Will get familiar with "math" module
    • Benefit of using functions in large program

    Code:


    GitHub Link:

    I have written very simple and well informative code. There are many places where you can reduce the size of code and optimise it.

    I encourage you to fork and star the repository on GitHub and make improvements. I will surely consider to add them.

    What Next:

    You can add many other functions to the program:
    • Add GUI (using Tkinter or other modules)
    • Add more operations in calculator
    • You can also add binary, decimal, hexadecimal and octal converter
    That's all for this project. Comment if any bugs or errors are present in the program. Comment any new ideas and yes, share this post so that others can learn something new

      Python Project - 1 (Password Locker)

      Hello reader, this is my first post on this blog. I created this blog for various purposes including First and most importantly improve my coding Help others to learn various concepts in programming  To complete my hobby of blogging So, I am starting various series simultaneously, hope I will able to continue them. In this " Python Project " series, I will create simple python projects and will give step by step procedure to do that. I think you should first try to complete code yourself, then if you get stuck anywhere, feel free to check steps, refer complete code or comment for more help. Let's begin... Idea and Need: You probably have accounts on many different websites. It is a bad habit to have the same password and it is difficult to remember all passwords. So it is a good idea to use "Password Manager Software". So why not create it yourself? So let's see what steps you should follow... Steps: We have to create a menu which has the...

      WDS15 - Handle your Metadata

      In the last short article we learned about: HTML iframe element to display webpage inside webpage Now in this article, we are going to see something which will not make the direct impact on how you are seeing your webpage but will do a lot of background work. So let's get started... In the very first article on HTML, while learning basic HTML page structure we divided HTML document into two main parts: head and body. This head contains metadata about HTML document which we write in the body of HTML. Ler's see how to write this metadata... HTML <meta> element <meta> element is used to specify about author of webpage, various tags for article, page description and many other things.

      In the last article we learned following tags to enhance your HTML: <b> and <strong> tags <i> and <em> tags <small> <del> <mark> <ins> <sup> and <sub> tags Now let's move forward from styling and see some HTML elements so that we can write quotes in our documents comfortably. HTML <q> tag for Short Quotations This <q> tag defines a short quotation in HTML. This is mostly used for short inline quotations. Most of the browsers insert quotation marks(") before and after the content in quotation tags. HTML <blockquote> tag for Large Quotations This <blockquote> tag defines large quotations in HTML. Browsers usually indent the content inside <blockquote> tags. HTML <abbr> for Abbreviations HTML <abbr> tag defines an abbreviation. This tag requires one extra attribute called title . This attribute takes full form for that particular abbrev...
