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 """ |

Creating a single file that can run both as a Python and a Rust program while printing "hello world" when executed in either environment is quite an interesting challenge. The trick is to find syntax that is valid (or can be made valid with some clever manipulation) in both languages, taking advantage of comments and preprocessor directives in a similar way to the C and Python example. Here's how you could do it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //fn main() { // println!("hello world"); //} /* def main(): print("hello world") if __name__ == "__main__": main() #*/ fn main() { println!("hello world"); } |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //fn main() { // println!("hello world"); //} /* def main(): print("hello world") if __name__ == "__main__": main() #*/ fn main() { println!("hello world"); } |
Running the following program:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | //fn main() { // println!("hello world"); //} /* def main(): print("hello world") if __name__ == "__main__": main() #*/ fn main() { println!("hello world"); } |

Creating a file that can be executed both as a Rust program and a Python script is an interesting challenge due to the syntactic and semantic differences between the two languages. However, by carefully crafting comments and utilizing the syntax rules of each language, it is possible to create a file that fulfills this requirement. Below is an example of how you could write such a file, named `foo.py.rs`:
1 2 3 | // fn main() {println!("hello world");} /* print("hello world") // */ |
1 2 | python foo.py.rs |
1 2 | rustc -o a.out foo.py.rs && ./a.out |
1 | hello world |
I extracted the following code from that output:
1 2 3 | // fn main() {println!("hello world");} /* print("hello world") // */ |
Running the following program:
1 2 3 | // fn main() {println!("hello world");} /* print("hello world") // */ |
