Underneath it is the toolbar:

On the right side is an interactive console where you can write and run lawmaking:

On the left is an editor where you can write and save Python scripts:

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

How to Get-go a Project in the Spyder IDE

In the Spyder IDE, every bit in other IDEs, nosotros tin can create a projection to organize our files, like images, scripts, and related text files. To create a project, simply select Projects › New Projection from the main bill of fare.

The Create new project window will display. Fill in the information for your project, including its name and directory (if the selected directory already exists, make sure the "Existing directory" radio button is selected at the height). When you're done, click the Create push button. Here, we chose the name "MyFirstProject."

You'll encounter the project folder in the Project explorer pane.

Writing Your First Python Script in Your Project

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

The New File dialog displays. Enter the proper name of your script (ours is MyFile), and click Salve. Remember to add 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 projection 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, like this:

print('This is my get-go script in Python')

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

Spyder IDE Features

Most IDEs assist you lot write ameliorate code. The Spyder IDE is no dissimilar!

Comments

One of the available features allows you lot to apace add block comments to your code. Click on the line where you'd similar to insert a block comment, then select Edit › Add block comment from the carte.

This volition insert a block comment like so:
