Run a program #IP1 - fails (Python)

[gnidocnuf]

I’m stuck on Stage #IP1.

Somewhat noob here.

Here are my logs:

 [compile] Moved ./.codecrafters/run.sh → ./your_program.sh
[compile] Compilation successful.

And here’s a snippet of my code:

import sys
import os 
from pathlib import Path 

def main():
    path = os.getenv("PATH")
    builtins = ["echo", "exit", "type"]

    while True:
        sys.stdout.write("$ ")
        
    # Wait for user input
        inp = input()
        inpsplit = inp.split()

        match inpsplit:
            case ["echo", *args]:
                print(*args)
            case ["exit", "0"]:
                sys.exit(0)
            case ["type", arg]:
                if arg in builtins:
                    print(f"{arg} is a shell builtin")
                elif res := search_in_dir(arg):
                    print(f"{arg} is {res}")
                else:
                    print(f"{arg}: not found")
            case _:
                if search_in_dir(inpsplit[0]):
                    print(f"Program was passed {len(inpsplit)} args (including program name).")
                    print(f"Arg #0 (program name): {inpsplit[0]}")
                    
                    for i, cm in enumerate(inpsplit[1:], start=1):
                        # print(f"Arg #{i}: {cm}")
                        sys.stdout.write(f"Arg #{i}: {cm}")
                else: 
                    print(f"{inp}: command not found")

def search_in_dir(commandName):
    dirs = os.environ["PATH"].split(":") 
    
    for d in dirs:
        path = Path(d) / commandName

        if path.exists():   
            return str(path)
    
    return None   
      
if __name__ == "__main__":
    main()

Hey @gnidocnuf, you’ll need to actually run the executable instead of hardcoding the output:

You can use subprocess.run to execute the command and capture its output.

Let me know if you need further clarification!
