Python isn't weakly-typed.
Over the years, I’ve used Perl a lot (that one doesn’t care if it’s int or string… no, correction, in Perl everything is a string, ints just don’t exist. Well, kind of). It’s probably the language designed for throw away coding. I’ve done some Python too (that’s like Perl, but with proper objects in it, and everything is a dictionary there).
The author has almost no real programming experience with Python. Perl experience seems to overlap with sysadmin-related work at least partially, where it's usually used as better Bash. All their repositories in GitHub are Rust. So almost all of "real" programming they did used Rust.
Why would anyone who know Rust way better than any other language prefer to do their prototypes using anything else?
