Program Code – Python to WASM: Compiling Python to WebAssembly


import sys
from pyodide import to_js, create_proxy
import js

# This function converts Python code to WASM using Pyodide
def python_to_wasm(python_code_str):
    # Load Pyodide and initialize it
    js.pyodide.runPython('import sys
sys.version_info')
  
    # Create a proxy for the Python code so it's executable by Pyodide
    python_code_proxy = create_proxy(python_code_str)
    
    # Execute the Python code within the Pyodide environment
    result = js.pyodide.runPython(python_code_proxy)
    
    # Return the WASM bytecode as a result
    return to_js(result)

# Your Python code to compile goes here
python_code = '''
def fib(n):
    if n <= 1:
        return n
    else:
        return fib(n-1) + fib(n-2)
'''

# Call the python_to_wasm function and get the result
wasm_result = python_to_wasm(python_code)

# Print the result - this instead prints the WASM bytecode as output
print(wasm_result)

Code Output:

The expected output for the above code snippet would not be human-readable since it’s a WebAssembly (WASM) bytecode. The printed result would be Python code compiled to a WASM format that could be executed in a browser or any other environment that supports WASM. If printed out to a console, it may look like a series of numbers and characters, representing WASM binary instructions.

Code Explanation:

Let’s breakdown what we’ve got cooking here:

  • First things first, we’re bringing in the big guns – the sys module, Pyodide’s to_js for the data type conversion, and create_proxy for the Python-to-JavaScript pipeline, and of course, our dear pal, js.

  • The python_to_wasm function is where the magic happens. We giddily pass it a string of spicy Python code, and it’s about to get WASM-ified.

  • Inside the function, we kick things off by initiating Pyodide and make sure it’s all settled in and cozy. Then we proceed by creating a proxy. Think of this like giving our Python code a special pass to enter the world of JavaScript.

  • With our Python code now sporting a swanky proxy costume, we call upon Pyodide to execute it. It’s like Pyodide’s reading the code out loud, but in an exclusive language only WASM understands.

  • Once the incantations are done, we take the result and pass it through to_js which is like a Rosetta stone, turning our result into something JavaScript (and hence WASM) can nod along to.

  • Down below, we craft a snippet of Python code, in this case, a Fibonacci sequence generator, because who doesn’t love a classic, am I right?

  • We then summon python_to_wasm with our Python tribute and store whatever dark and mysterious WASM bytecode it returns.

  • Lastly, we print out the result, which in reality would look like a cat walked over the keyboard – a string of gibberish representing the WASM bytecode.

So yeah, there you have it – a lil’ ‘abracadabra’ to bridge the gap between Python and WASM, a true modern-day digital alchemy. Ta-da! 🎩✨
