import subprocess

# Execute Command Literal
# Make sure to replace <placeholders> with actual values
def run_command():
    cmd = [
        "program",
        "<program>"
    ]
    
    try:
        print(f"Executing: {' '.join(cmd)}")
        subprocess.run(cmd, check=True)
    except subprocess.CalledProcessError as e:
        print(f"Error: {e}")
    except FileNotFoundError:
        print("Error: program not found. Please install it first.")

if __name__ == "__main__":
    run_command()

When To Use

During tasks where explicit command execution is required, such as testing scripts directly.

Pro Tip

Using a full path for the program helps avoid alias confusion and ensures the correct binary is executed.
