Title: Nu Command Equivalents in Other Languages (Continued)

Summary

This section provides Nu command equivalents in Python, Kotlin (Java), C++, and Rust for commands such as `rename`, `reverse`, `rm`, `save`, `select`, `shuffle`, `str stats`/`str length`/`length`, `skip`, `skip until`, `skip while`, `sort-by`, `split row`, and `str`. It details how similar operations can be performed in these other programming languages.
