Ensure print_callback runs before formatting print args

[ghost]

Description

This pull request addresses the issue where the print_callback needs to be executed before formatting print arguments. Currently, the issue arises as repr() generates output that is not valid code, causing a break in the black formatting of the output.

Changes Made

• Added a pre-execution step for print_callback to ensure it runs before formatting print arguments. This helps prevent repr() from creating output that breaks the black formatting of the output.

How to Test

1. Ensure the print_callback is triggered before formatting print arguments.
2. Verify that the black formatting of the output is not disrupted by invalid code generated by repr().
