Python console

Last modified: 01 April 2025

Tools | Python Console

Python console enables executing Python commands and scripts line by line, similar to your experience with Python Shell.

Working with Python console

The console appears as a tool window every time you choose the corresponding command on the Tools menu. You can assign a shortcut to open Python console: press CtrlAlt0S, navigate to Keymap, specify a shortcut for Main menu | Tools | Python or Debug Console.

The main reason for using the Python console within PyCharm is to benefit from the main IDE features, such as code completion, code analysis, and quick fixes.

Code completion in the Python console

You can use up and down arrow keys to browse through the history of executed commands, and repeat the desired ones. To preview the variable values calculated in the course of the execution, click Show variables and check the Special Variables list.

Show variables in the Python console

The console is available for all types of Python interpreters and virtual environments, both local and remote.

View data structures

  • When viewing variables in the Python Console, you can click View as Array, View as DataFrame, or View as Series links to display the data in the Data View tool window.

    Viewing data frames

  • By default, the new table representation is used.

    Click More Actions and select Switch Between Table Representations Switch Between Table Representations to change the table interface.

    note

    PyCharm will remember your choice and use the selected table representation in the future, except for the data structures from the newly supported libraries (for example, polars), which will always be displayed using the new representation.

Run source code from the editor in console

  1. Open file in the editor, and select a fragment of code to be executed.

  2. From the context menu of the selection, choose Execute Selection in Python Console, or press AltShift0E:

    Context menu for executing the code selection

    note

    With no selection, the command changes to Execute line in console. Choose this command from the context menu, or press AltShift0E. The line at caret loads into the Python console, and runs.

  3. Watch the code selection execution:

    Execution of the code selection in the console

By default, the Python console executes Python commands using the Python interpreter defined for the project. However, you can assign an alternative Python interpreter.

Run asyncio coroutines

  1. In the editor, select a fragment of code which contains the definition of an asyncio coroutine.

  2. From the context menu, select Execute Selection in Python Console, or press AltShift0E:

    Selecting and executing asyncio coroutines in the Python console

  3. After the code is executed on the Python console, run the coroutine by using the await keyword:

    Execution of the asyncio coroutine in the console

Configure Python console settings

  1. In the Settings dialog (CtrlAlt0S) , select Build, Execution, Deployment | Console | Python Console.

  2. Select any available interpreter from the Python interpreter list. Note that you cannot introduce a new interpreter here. If you want to come up with the new interpreter, you need to create it first.

    Search an alternative Python interpreter

  3. In needed, click the Configure Interpreters link to inspect the list of the installed packages and add new ones.

    Mind the code in the Starting script area. It contains the script that will be executed after you open the Python console. Use it to pre-code some required Python commands.

When working on several Python scripts, you might want to execute each in a separate Python console.

Run several Python consoles

  1. Click New Console to add a new Python console.

  2. By default, each console has the name Python Console with an index. To make a console reflect the script you're running, right-click the console tab, select Rename Console, and enter any meaningful name.

    Rename the Python console

All the commands you're running in the Python console are executed one by one. If the commands require substantial time to get executed, you might want to preview and manage the execution queue.

Manage the command execution queue

  1. Go to Settings | Build, Execution, Deployment | Console and enable the Command queue for Python Console checkbox.

  2. Click Command queue on the console toolbar to open the queue.

    Console command queue

  3. In the Python Console Command Queue dialog, review the list of commands. If needed, click remove to delete the command from the queue.

Note, once the command is executed, it disappears from the queue. To preview all previously executed commands browse the console history (console history).

Rerun console

Rerun console

CtrlF5

Click this button to terminate the current process and launch the new one.

the Stop button

Stop

CtrlF2

Click this button to stop the current process.

Clicking the button once invokes soft kill allowing the application to catch the SIGINT event and perform graceful termination (on Windows, the Ctrl+C event is emulated). After the button is clicked once, it is replaced with the Kill Process button indicating that subsequent click will lead to force termination of the application, for example on Unix SIGKILL is sent.

Run command

Execute Current Statement

Enter.

Click this button to execute the command at caret, entered in the input pane of the console.

Debug

Attach Debugger

Attaches the debugger process to the console.

Settings

Settings

You can specify the following settings of the Python console:

  • Simplified Variables View: Select this option to include the following names into the Special Variables group:

    • all variables with the dunder names.

    • all instances of function, classobj and module.

    • all the IPython internal variables, if debug console with IPython has been started.

  • Variables Loading Policy. You can choose one of the following policies:

    • Synchronously: If this option is enabled, the message shown is Collecting data, and after that the debugger shows the variables' values.

    • Asynchronously: If this option is enabled, the variables in the debugger are loaded separately (asynchronously). In this case, if loading a variable takes a long time, the debugger shows ...Loading Value message, and only after that it shows its value or the Loading timed out message, if the variable is too slow. Mind the warning message that suggest switching to the on demand mode.

    • On demand: If this option is enabled, the debugger shows Show Value message. Click it to enable loading.

    Note that any changes in the loading policies become effective after you rerun the debugging process.
