Python script

Definition

A Python script is a program written in Python and usually saved in a .py file. Python scripts are commonly used for automation, data processing, file handling, testing, and integrations.

Why it matters

Python is popular because it is readable and has a large ecosystem of libraries. Even in web projects that are not built with Python, Python scripts may appear in data, tooling, or automation workflows.

Example in VCA

In VCA, a learner might compare a Python script with a Node.js script to understand that both can automate tasks, even though they use different languages and runtimes.

Another Real World Example

A data team might use a Python script to clean a spreadsheet and prepare it for import into a database.

Common mistakes

• Running a script with the wrong Python version.
• Forgetting to install required packages.
• Mixing local file paths that only work on one computer.
• Not using a virtual environment for project dependencies.
• Running data-changing scripts without a backup or dry run.
