Write a single file that I can save as foo.py.rs that I can run as either a rust program or a python program, and so both will print "hello world". Specifically if I run `python foo.py.rs` or `rustc -o a.out foo.py.rs && ./a.out` I should see "hello world" printed to the console. To help you out, here's a valid answer for how to do this in C:
1 2 3 4 5 6 7 8 9 10 11 12 | #include <stdio.h> #define sdf b /* print("hello world") """ #define wer b */ int main() { printf("hello world "); } #define ert s """ |

To create a polyglot Rust-Python file that prints "hello world" when run by either interpreter, we can leverage comments and string literals in a way that each language ignores the other's code. Here's how:
1 2 3 4 5 6 7 8 | /* print("hello world") """ */ fn main() { println!("hello world"); } // """ |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 | /* print("hello world") """ */ fn main() { println!("hello world"); } // """ |
Running the following program:
1 2 3 4 5 6 7 8 | /* print("hello world") """ */ fn main() { println!("hello world"); } // """ |
hello world
Testing if the previous output contains the string hello world
: True
