Output
It's unfortunately not possible to create a single file that can be executed directly as both a valid Python and Rust program. This is due to the fundamental differences in their syntax and compilation processes.
**Here's why:**
* **Syntax:** Python and Rust have completely different syntax. Trying to interleave them like in the C example would lead to syntax errors in both languages.
* **Compilation:** Rust is a compiled language, meaning it needs to be converted to machine code by a compiler (`rustc`) before it can be run. Python is an interpreted language, meaning it's executed line by line by the Python interpreter.
**Alternatives:**
While a single, directly executable file isn't feasible, here are some alternatives to achieve a similar goal:
1. **Separate Files with a Launcher Script:**
- Create a Python file (e.g., `foo.py`) and a Rust file (e.g., `foo.rs`).
- Write a shell script (e.g., `run.sh`) that:
- Checks for an argument (e.g., `python` or `rust`).
- Based on the argument, executes the corresponding file.
**foo.py:**
**foo.rs:**
| fn main() {
println!("hello world");
}
|
**run.sh:**
| #!/bin/bash
if [ "$1" == "python" ]; then
python foo.py
elif [ "$1" == "rust" ]; then
rustc foo.rs -o foo && ./foo
else
echo "Usage: ./run.sh [python|rust]"
fi
|
**Usage:**
| ./run.sh python # Runs the Python version
./run.sh rust # Runs the Rust version
|
2. **Using a Shebang and File Extension Trickery (Less Reliable):**
- You could potentially use a shebang line pointing to the Python interpreter and name your file with a `.py.rs` extension. This would allow Python to run it.
- However, this relies on the Python interpreter ignoring the `.rs` part of the extension and wouldn't work for Rust compilation.
**foo.py.rs:**
| #!/usr/bin/env python3
print("hello world")
# This won't compile as valid Rust
|
**Usage:**
| python foo.py.rs # Works
rustc foo.py.rs # Fails to compile
|
**Recommendation:**
The first approach (separate files with a launcher script) is much cleaner, more reliable, and clearly separates the Python and Rust code.

Output
Unfortunately, creating a single file that can be directly executed as both a Python and Rust program is not possible. This is because:
* **Different Syntax and Semantics:** Python and Rust have fundamentally different syntax and language rules. A valid Python statement might be meaningless or an error in Rust, and vice versa.
* **Compilation vs. Interpretation:** Rust is a compiled language, meaning you need to compile it into machine code before execution. Python is interpreted, meaning it's executed line by line without a separate compilation step.
While you can't achieve this direct dual-execution, here are some workarounds and alternatives:
**1. Conditional Execution with Shebang and File Extension Check:**
You could create a file that checks its own extension or uses a shebang to determine how it's being run. However, this requires renaming the file for each language.
| #!/usr/bin/env python
import sys
if __name__ == "__main__" and sys.argv[0].endswith(".py"):
print("hello world")
|
Save this as `foo.py` and then run `chmod +x foo.py` to make it executable. Now you can run it with `./foo.py`.

if args.len() > 0 && args[0].ends_with(".rs") {
println!("hello world");
} else {
exit(1);
}
}
|
Save this as `foo.rs` and then run `rustc foo.rs -o foo` to compile it. Now you can run it with `./foo`.
**2. Separate Files with a Common Entry Point:**
A more structured approach is to have separate Python and Rust files that call a common function defined in a third file (e.g., using a Python module or Rust FFI).
**3. Using a Tool Like Mypyc:**
Tools like Mypyc can compile Python code (with type annotations) to C extensions, potentially making it easier to integrate with Rust.
**Key Point:** The fundamental differences between Python and Rust make truly seamless dual-execution in a single file impossible. The workarounds involve clever tricks but require compromises or external tools.

Unfortunately, what you're asking for isn't directly achievable in the same way it might be with C and Python.
**Here's why:**
* **Fundamentally Different Languages:** Rust and Python are fundamentally different in how they are parsed, compiled, and executed.
* **Rust** is a statically-typed, compiled language. It requires compilation into machine code before it can run.
* **Python** is a dynamically-typed, interpreted language. It's executed line by line by the Python interpreter.
* **No Shared Preprocessing:** Unlike C, where the C preprocessor can be used to manipulate the code before compilation (as in your example), Rust and Python don't share a preprocessing step.
**Alternatives (Not a single file solution):**
While a single file solution isn't feasible, here are some alternative approaches to achieve a similar outcome:
1. **Separate Files with a Build Script:**
* Create separate Rust (`main.rs`) and Python (`main.py`) files.
* Use a build script (e.g., `Makefile`, `bash` script) to:
* Compile the Rust file: `rustc main.rs -o main`
* Run the appropriate executable based on user input or file extension.
2. **Foreign Function Interface (FFI):**
* Create a Rust library that exposes a function to print "hello world".
* Use Python's FFI (ctypes or cffi) to call the Rust function from your Python script.
**Example (Separate Files with Build Script):**
| # build.sh
#!/bin/bash
if [[ "$1" == "rust" ]]; then
rustc main.rs -o main
./main
elif [[ "$1" == "python" ]]; then
python main.py
else
echo "Usage: ./build.sh [rust|python]"
fi
|
**main.rs:**
| fn main() {
println!("hello world");
}
|
**main.py:**
**To run:**
* Compile and run Rust: `./build.sh rust`
* Run Python: `./build.sh python`

Output
Unfortunately, achieving this directly in a single file named "foo.py.rs" that functions as both valid Python and Rust code is not feasible. Here's why:
* **Syntax Incompatibility:** Python and Rust have fundamentally different syntax rules. What's valid in one language will typically be a syntax error in the other.
* **Compilation vs. Interpretation:** Rust is a compiled language, requiring compilation to machine code before execution. Python is interpreted, meaning it's executed line by line without a separate compilation step.
**Alternative Approaches:**
While a single file solution isn't viable, here are alternative ways to achieve a similar outcome:
1. **Separate Files:** The most straightforward approach is to maintain separate Python and Rust files:
- `foo.py`:
- `foo.rs`:
| fn main() {
println!("hello world");
}
|
2. **Conditional Compilation (Advanced):** You could explore conditional compilation using build tools like `make` to selectively include or exclude code based on the target language. However, this would still involve separate code sections within the file and wouldn't make the file directly executable by both Python and Rust interpreters/compilers.
**Example using `make`:**
| all: foo.py foo.rs
foo.py:
echo "print('hello world')" > foo.py
foo.rs:
echo "fn main() { println!(\"hello world\"); }" > foo.rs
|
This Makefile will generate separate `foo.py` and `foo.rs` files when you run `make`.
**Key Takeaway:** Due to the inherent language differences between Python and Rust, a true single-file solution that behaves as both is not realistically achievable. Separate files or build system tricks are necessary to manage this duality.

Unfortunately, you can't achieve this with Rust and Python in the same way you can with C. Here's why:
* **Fundamentally Different Languages:** Rust and Python have drastically different syntax and compilation models. C's preprocessor allows for simple text replacement, which can be exploited for this kind of trickery. Rust and Python don't share a similar mechanism.
* **Rust Compilation:** Rust is a compiled language. You need `rustc` to compile your code into an executable before you can run it.
* **Python Interpretation:** Python is an interpreted language. It's executed line by line by the Python interpreter.
**Alternative Approaches (Not a Single File Solution):**
While a single file solution is impossible, you can explore these alternatives:
1. **Separate Files with Foreign Function Interface (FFI):**
* Create a Rust library exposing a function (e.g., `print_hello_world`).
* Use Python's `ctypes` module to load the Rust library and call the function.
**Rust (hello.rs):**
| #[no_mangle]
pub extern "C" fn print_hello_world() {
println!("hello world");
}
|
**Python (main.py):**
| import ctypes
rust_lib = ctypes.CDLL("./target/release/libhello.so") # Adjust path as needed
rust_lib.print_hello_world()
|
2. **Subprocesses:**
* Create separate Rust and Python files.
* From Python, use the `subprocess` module to execute the compiled Rust binary.
**Rust (hello.rs):**
| fn main() {
println!("hello world");
}
|
**Python (main.py):**
| import subprocess
subprocess.run(["./hello"]) # Assuming 'hello' is the Rust executable
|
**Key Points:**
* These alternatives require separate files and potentially some build system configuration.
* FFI provides tighter integration but can be more complex.
* Subprocesses are simpler but involve separate process execution overhead.
