Spyder IDE Carte du jour and Toolbar Overview

The main window of the Spyder IDE contains a master menu, toolbar, and several panes. At the top is the main menu:

Underneath it is the toolbar:

On the right side is an interactive panel where y'all can write and run code:

On the left is an editor where y'all can write and save Python scripts:

To the left of the editor is the Project Explorer pane, which displays all projection nodes with their related folders and files:

How to Commencement a Projection in the Spyder IDE

In the Spyder IDE, equally in other IDEs, we tin create a project to organize our files, like images, scripts, and related text files. To create a projection, simply select Projects › New Projection from the chief card.

The Create new project window volition display. Fill in the information for your project, including its name and directory (if the selected directory already exists, make certain the "Existing directory" radio push button is selected at the top). When y'all're done, click the Create push button. Here, we chose the proper noun "MyFirstProject."

You'll run across the project binder in the Projection explorer pane.

Writing Your Starting time Python Script in Your Project

Every projection contains files: code, pictures, libraries, text files, and more. We'll create a file that allows us to write a Python script. Right-click on your project folder, and cull New › File.

The New File dialog displays. Enter the name of your script (ours is MyFile), and click Save. Remember to add together a .py extension at the end of name of the file proper noun to designate it as a Python script.

Your file will appear under your project folder in the Project explorer pane of the IDE.

The file will also automatically be opened in the Editor pane. Here, we can write Python code, similar this:

print('This is my showtime script in Python')

You tin so save your file by pressing Ctrl+S or choosing File › Salve from the menu.

Spyder IDE Features

Nearly IDEs help you write better code. The Spyder IDE is no different!

Comments

One of the bachelor features allows you to quickly add block comments to your lawmaking. Click on the line where you lot'd like to insert a block comment, and so select Edit › Add together block comment from the menu.

This will insert a block comment like and then:

In a similar style, you can remove cake comments using the Edit carte du jour—just click within the annotate cake, and choose Remove cake comment.

Syntax Highlighting

If you look at the code in your editor, you'll see many different colors: strings are in green, brackets in bright dark-green, the names of functions are violet. This is known every bit syntax highlighting—a feature that most text editors accept to arrive easier for you lot to notice relevant parts of your lawmaking.

If y'all make a syntax fault in your code (here, omitting a closing bracket for a list), the IDE volition inform you of it with a red x icon. You lot can hover your mouse over it for more information.

Spyder IDE besides provides a completion feature during coding. If you start writing a Python keyword and forget the balance of the spelling, the IDE will offer a listing of suggestions. For example, if we type simply the character i and printing Tab or Ctrl+Space, nosotros'll run across a dropdown list of keywords starting with the alphabetic character 'i'. Yous tin choose one of the suggestions or continue typing.

How to Run Python Lawmaking in the Spyder IDE

We can run project files using the dark-green Run button from the toolbar. Alternatively, yous can select Run › Run from the main menu or use the shortcut key (F5).

You'll see the effect of running your currently active file in the Console pane:

All the same, sometimes we brand non-syntactic errors when coding. In this situation, later running your code, you'll encounter the error summary in the Panel pane.
