# Why Does My Python Script Work Locally but Fail on the Server?

A small Python script runs normally on my laptop but fails when I deploy it to a server. The error mentions a configuration value that exists in my local setup, so I’m wondering whether I’m overlooking an environment difference rather than a bug in the script itself.

For this kind of issue, what details are most useful to compare first—Python and package versions, file paths, permissions, or **Python environment variables**? I’d also appreciate tips for reproducing the server setup locally without copying sensitive credentials into the project.
