How to Run Code in PyCharm
Learning how to run code in PyCharm is the process of executing Python scripts within JetBrains’ integrated development environment using run configurations, keyboard shortcuts, or context menus.
You need this when testing scripts, debugging applications, or verifying code changes during development.
This guide covers 7 methods requiring 3-5 minutes and basic familiarity with the PyCharm IDE.
Prerequisites
Before running any Python script, confirm these requirements:
- PyCharm version: Community Edition 2023.x or Professional Edition installed
- Python interpreter: Python 3.8+ configured in your project
- Project setup: At least one .py file created in your project structure
- Time estimate: 3-5 minutes to complete all steps
Need to add a Python interpreter in PyCharm first? Do that before continuing.
If you haven’t configured your environment yet, learn how to setup PyCharm properly.
Step One: How Do You Run Code Using the Context Menu?
Right-click anywhere inside your Python file editor to access the context menu, then select “Run [filename]” to execute the script in the Run tool window.
Action
- Location: Right-click inside the code editor area
- Menu path: Run ‘[your_filename]’
- Result: Script executes; output appears in Run tool window at bottom of screen
Purpose
The context menu method works best for quick, one-off script execution without memorizing shortcuts.
PyCharm automatically creates a temporary run configuration when you use this method.
Step Two: How Do You Run Code Using Keyboard Shortcuts?
Press Ctrl+Shift+F10 (Windows/Linux) or Control+Shift+R (macOS) to instantly run the current Python file without touching your mouse.
Action
- First run: Ctrl+Shift+F10 (Windows/Linux) or Control+Shift+R (macOS)
- Re-run last script: Shift+F10 (Windows/Linux) or Control+R (macOS)
- Result: Console output displays in Run tool window
Purpose
Keyboard shortcuts provide the fastest execution method during active software development.
Once you run a script, Shift+F10 re-executes it instantly. Saves significant time during iterative testing.
Step Three: How Do You Run Code Using the Gutter Icon?
Click the green play icon in the gutter (left margin beside line numbers) next to any runnable code block like a main function or class definition.
Action
- Location: Green triangle icon in the left gutter area
- Click action: Select “Run ‘[filename]'” from the popup menu
- Result: Code executes; output shows in Run tool window
Purpose
The gutter icon appears automatically next to if name == 'main': blocks and test functions.
This visual indicator helps beginners locate exactly where execution will start. Also useful when your file contains multiple runnable entry points.
Want to step through code line by line instead? Learn how to debug in PyCharm for breakpoint-based execution.
Step Four: How Do You Run Code Using the Run Menu?
Access Run > Run from the main menu bar or press Alt+Shift+F10 to open a popup showing all available run configurations for your project.
Action
- Menu path: Run > Run from the top menu bar
- Shortcut: Alt+Shift+F10 opens configuration selector
- Selection: Choose your script from the popup list
Purpose
The Run menu provides access to all saved run/debug configurations in one place.
Best for projects with multiple entry points or when switching between different scripts frequently.
Step Five: How Do You Run Code Using the Run Widget?
The Run Widget sits in the top toolbar, displaying the currently selected configuration with a green play button for instant execution.
Action
- Location: Top-right area of the main toolbar
- Selection: Click dropdown to choose “Current File” or a saved configuration
- Execution: Click the green play icon to run
Purpose
The widget offers one-click execution without navigating menus. Always visible during coding sessions.
Step Six: How Do You Run Code in the Python Console?
Open Tools > Python Console to launch an interactive interpreter where you can execute code line by line or run selected code fragments.
Action
- Console path: Tools > Python Console from main menu
- Run selection: Highlight code, press Alt+Shift+E
- Result: Code executes in interactive console with immediate output
Purpose
The Python Console excels at testing code snippets, exploring APIs, and quick experimentation without running entire scripts.
Supports IPython if installed. Great for data analysis workflows.
Step Seven: How Do You Run Code Using the Terminal?
Open the integrated terminal window at the bottom of PyCharm and execute Python scripts using standard command-line syntax.
Action
- Terminal access: View > Tool Windows > Terminal (or Alt+F12)
- Command syntax:
python filename.pyorpython3 filename.py - Result: Output displays directly in terminal
Purpose
Terminal execution mirrors production environment behavior. Required for scripts needing command-line arguments or specific environment variables.
Also useful when working with virtual environments in PyCharm that need manual activation.
Verification
Confirm successful code execution by checking these indicators:
- Run tool window: Shows “Process finished with exit code 0” for successful runs
- Output panel: Displays expected print statements or return values
- Exit code: 0 means success; non-zero indicates errors
If your script produces no visible output, add a simple print("Script completed") statement at the end to verify execution.
Troubleshooting
Issue: No Python Interpreter Configured
Solution: Navigate to File > Settings > Project > Python Interpreter, click the gear icon, select “Add Interpreter” and choose your Python installation path.
Need packages? Learn how to install packages in PyCharm after configuring your interpreter.
Issue: Run Option Grayed Out
Solution: Verify your file has a .py extension. Check that PyCharm recognizes the file as Python by looking for syntax highlighting.
Sometimes you need to create a new project in PyCharm with proper Python SDK configuration.
Issue: ModuleNotFoundError When Running
Solution: Check your working directory in Run Configuration settings matches your project root. Verify the module is installed in your active interpreter.
Missing libraries? See how to install libraries in PyCharm for package management.
Issue: Wrong Python Version Executing
Solution: Multiple Python installations can cause conflicts. Review how to change Python version in PyCharm to select the correct interpreter.
