Error during connection with WebSocket in Python TypeError str object is not callable

WebSocket is a communication protocol that provides full-duplex communication channels over a single TCP connection. It is commonly used in web development for real-time applications. However, during the implementation of WebSocket in Python, you might encounter the TypeError: 'str' object is not callable error. This tutorial will guide you through understanding and resolving this error.
The TypeError: 'str' object is not callable error typically occurs when you mistakenly attempt to call a string object as if it were a function. In the context of WebSocket connections in Python, this error might arise due to incorrect usage of a string where a function or method is expected.
Incorrect Assignment: You might be trying to assign a string to a variable that should hold a callable function or method.
Misuse of Parentheses: Check if you are accidentally trying to call a string using parentheses, as if it were a function.
Let's consider a simple WebSocket connection using the websockets library in Python. Suppose you have the following code:
In this example, you might encounter the TypeError: 'str' object is not callable error if there is an issue with the on_message function or its usage.
To resolve the error, carefully review the code and ensure that you are using functions and methods correctly. In the example above, make sure that on_message is a function and is not accidentally assigned a string value.
Here's a corrected version:
In this corrected version, ensure that you are using await when calling the on_message function within the connect_websocket coroutine.
The TypeError: 'str' object is not callable error in the context of WebSocket connections in Python usually indicates a misuse of strings where functions or methods are expected. Carefully review your code, check function assignments, and ensure proper usage of parentheses to resolve the error.
