import sysimport subprocessdef install(package):subprocess.check_call([sys.executable, "-m", "pip", "install", package])# Example: Ensure 'requests' is installed before using ittry:import requestsexcept ImportError:install("requests")import requestsprint(requests.get("https://httpbin.org/get").status_code)Copied!✕Copysys.executable ensures the correct Python environment is used.
