python --version

If Python is not installed, download it from python.org and add it to your system PATH.

Step 3: Install the Atom-Runner Package

Atom-Runner is a package that allows you to execute code directly within Atom. Install it using one of these methods ?

Method 1: Using Command Line

Open your terminal and run ?

apm install atom-runner

Method 2: Using Atom Interface

• Open Atom
• Go to File ? Settings ? Install
• Search for "atom-runner"
• Click Install on the atom-runner package

Step 4: Configure Atom-Runner Settings

After installing atom-runner, configure it for optimal Python execution ?

1. Go to File ? Settings ? Packages
2. Find "atom-runner" in the installed packages list
3. Click Settings
4. Ensure the package is enabled
5. Optionally, customize the runner commands for Python

Step 5: Write and Execute Python Code

Now you can create and run Python programs directly in Atom ?

Creating a Python File

1. Open Atom
2. Create a new file (Ctrl+N or Cmd+N)
3. Save the file with a .py extension
4. Write your Python code

Example Python Program

# hello.py
def greet(name):
    return f"Hello, {name}!"

print(greet("Python"))
print("Welcome to Atom!")

# Simple calculation
numbers = [1, 2, 3, 4, 5]
total = sum(numbers)
print(f"Sum of {numbers} = {total}")

Running the Code

Execute your Python code using these keyboard shortcuts ?

• Ctrl+Shift+B (Windows/Linux) or Cmd+Shift+B (macOS)
• Or right-click and select Run Code
• Or use the command palette: Ctrl+Shift+P and type "atom-runner run"

The output will appear in a panel at the bottom of the Atom window.

Alternative: Using Script Package

Another popular option is the "script" package, which also allows code execution ?

apm install script

With the script package, use Ctrl+Shift+B to run Python files. It provides similar functionality with additional language support.

Troubleshooting Common Issues

Conclusion

Setting up Python in Atom is straightforward with the atom-runner package. This configuration allows you to write, execute, and debug Python code efficiently within a single environment, making it an excellent choice for Python development workflows.
