How to choose a Python code editor?

You can use any text editor for Python programming. For example, Notepad or GEdit. For greater convenience, you can choose such editors as Notepad++ or Sublime Text. They support automatic code formatting and syntax highlighting. There are also code editors that have code debugging tools, auto-completion and IntelliSense, easy navigation, and many other useful features.

Another way to write Python code is to use an integrated development environment (IDE), which includes different development tools in a single application. The final choice of code creation program depends on your needs.

How to create a Python script file

Create a folder on your computer in which you will save Python files. Open the folder in your code editor and create a file called Place the following Python commands in it:

In this example, we created a variable radius and assigned it a value of 10. After that, we calculated the area of a circle with a given radius and printed the result on the screen.

Now let’s complicate this example. The radius variable will be entered by the user, and the value of the circle area will be calculated in a function that will have one input argument and return the result.

If a non-integer value is specified when entering the radius, the program will generate an error. You should use the try-catch block to handle errors in Python programs.

If you want the created code to run several times, you need to use a loop. Let’s add a while loop to the created example, which will allow us to calculate the area of the circle 5 times for different radiuses.

How to run Python script?

To run the created script, open the folder containing the script file in the command line and execute the following command:
