Can someone help me with this.
I have been troubleshooting for the past week but no avail.

Thank You.

It appears that that PYZK uses the socket module to make it's connections (to a timeclock system or similar, I'm guessing). The socket module is one of the modules not fully supported/supportable in Pyodide due to limitations within the browser-window environment - the browser simply doesn't provide access to the same kind of low-level networking primitives that a native OS does.

One potential way around this, though not a simple one, would be to re-implement the connection using a WebSocket, the in-browser equivalent of a socket. Perhaps by subclassing the ZK Class or similar?

Since this is not a PyScript-specific issue, I'm going to convert it to a Discussion.
