zipfile module error

[pseudo]

hi. first of all I have to tell you that I'm a noob.
I'm trying to extract a zip file that gets downloaded and I get error
I double checked but I can't find the mistake

PS: how do I check if ffmpeg already exists and only run it after the first time when it's been updated. should use a checksum check?

    except ImportError:
        # 'requests' is not installed, so install it
        subprocess.check_call(["pip", "install", "requests"])
        print("requests module installed successfully.")
