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 single file that can be run as both a Rust program and a Python program, you can use a combination of Rust's `main` function and Python's `print` statement, while carefully structuring the code so that it is valid in both languages. Here's how you can do it:
1 2 3 4 5 6 7 8 | // This is a Rust comment, but Python will ignore it fn main() { println!("hello world"); } /* # This is a Python comment, but Rust will ignore it print("hello world") */ |
1 2 | python foo.py.rs |
1 2 | rustc -o a.out foo.py.rs && ./a.out |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 | // This is a Rust comment, but Python will ignore it fn main() { println!("hello world"); } /* # This is a Python comment, but Rust will ignore it print("hello world") */ |
Running the following program:
1 2 3 4 5 6 7 8 | // This is a Rust comment, but Python will ignore it fn main() { println!("hello world"); } /* # This is a Python comment, but Rust will ignore it print("hello world") */ |
hello world
Testing if the previous output contains the string hello world
: True
Running the following program:
1 2 3 4 5 6 7 8 | // This is a Rust comment, but Python will ignore it fn main() { println!("hello world"); } /* # This is a Python comment, but Rust will ignore it print("hello world") */ |
File "/usr/src/app/main.py", line 2
// This is a Rust comment, but Python will ignore it
