Refer to the exhibit. A developer got this output during the development of an application. Which action produces this output?

Executing a Python script with numpy produces numerical computation results or array output, not the structured +/- line comparison format shown in the exhibit.

Enhancing a numpy library would produce build, compilation, or installation log output, not a unified diff file comparison.

Uploading a script to a git repository produces git push confirmation and remote tracking messages, not a diff comparison of file contents.

The unified diff format - produced by 'diff -u' or tools such as git diff - displays file changes with a header identifying the source and target files, followed by hunk markers (@@) indicating line positions, where '-' prefixed lines were removed and '+' prefixed lines were added. This format is the standard for comparing two versions of a text file and is commonly seen in code review and version control workflows. The structured +/- output shown in the exhibit is the defining characteristic of unified diff, not of any Python execution or repository operation.
