Run Python code

Last modified: 08 September 2023

Once you have created a Python file and configured a virtual environment, you can execute your code.

The Python editor toolbar provides quick access to the most popular actions:

Icon

Action

new cell

Adds a code cell below the selected cell.

Cut

Moves the selected code cell the current location to the clipboard.

Copy

Copies the selected code cell to the clipboard.

Paste

Inserts the contents of the clipboard into a new code cell below the selected one.

Move cell up

Moves the current cell up.

Move cell down

Moves the current cell down.

Run cell

Executes this cell and selects a cell below. If there is no a cell below, DataSpell will create it.

the Run All button

Runs code of the Python file in the Python Console.

Debug Python code

Starts debugging Python code.

remove the cell

Deletes the current cell.

You can execute your script in the interactive read-evaluate-print loop (REPL) Python Console. You can even execute a selected fragment of your code, or a Python code cell.

Python console

Python console enables executing Python commands and scripts line by line, similar to your experience with Python Shell. The console is located in the lower group of the DataSpell tool windows and it opens each time you initiate code execution in it. You can also open it by selecting Windows | Tool Windows | Python Console from the main menu.

Run a file in the Python Console

  • To run a Python script in the console, click the Run button on the Python editor toolbar.

    The Run button on the toolbar

Once you initiate running, the Python Console opens and you should see the code execution.

Running file in the Python Console

By default, each console has a name that corresponds to the filename of the executed file with the index. So, if you want to execute sample.py in a new console, it will be run in the tab with the name sample (1). Use the list in the upper-right corner of the Python editor to select a particular console you need.

Running a file in several consoles

To rename a console tab, right-click it, select Rename Console, and enter any meaningful name.

Renaming the console tab

The renamed console is shown in the list of the consoles:

Renamed console

Run code in a non-interactive console

If the way you execute your Python script doesn't imply any interactivity, you can run it in a non-interactive console, similar to running code in the Run tool window.

  • Select Non-Interactive Shell from the list of controls and click the Run All button.

Run code cells

You can format your Python code as a set of executable cells to run each separately.

  1. To split your code into cells, add # %% lines where appropriate.

  2. Each cell has a Run icon (the Run button) in the gutter. Click it to execute a cell. Mind code dependencies and required imports. In the following example, the kernel_stats variable is defined in the first cell. So, running the second cell first results in NameError:

    Running the second cell

You can preview all commands executed in the current session of the selected Python console.

View console query history

  1. Select a target console and click Browse Query History on the console toolbar.

  2. Preview the list of the executed commands in the history dialog:

    Query history dialog

    You can select any item in the list and click the Paste button to copy and paste the related commands into the current Python console

  3. Once the commands are added, press Enter to execute them.

    Execute commands from the Python console query history

Use the Python Console toolbar to configure the way DataSpell present the execution output.
