The Calculator
We'll make a calculator that takes two integers and performs one of the basic mathematical operators on them: addition; subtraction, multiplication; or division.
This isn't too difficult, but it does introduce a couple of things that are slightly tricky.
Using Python
Open IDLE.
- You need to find and open IDLE (Python 3.8 64-bit)
- Once it opens, you'll have a window with some writing in it
- IMPORTANT – click File > New File. This opens a new window with nothing at all in it. This is where you'll write your program
The IMPORTANT bit is important!
If you try and write a program in the window with words in it, you won't be able to save it properly. Which would be bad.
