ConnectionError
In Python, ConnectionError is a built-in exception that signals issues related to network connectivity. This exception is part of the OSError family, and it typically arises when a network operation fails due to problems like unreachable hosts, refused connections, or broken pipes.
You can use ConnectionError to handle network-related errors in your code. This can help you implement robust error-handling strategies, such as retrying failed network requests or logging issues for further investigation.
ConnectionError Occurs When
A network operation fails due to problems like unreachable hosts, refused connections, or broken pipes.
ConnectionError Can Be Used When
- Handling errors when trying to connect to a remote server or service
- Managing exceptions during HTTP requests that fail due to connectivity issues
- Capturing connection failures in client-server applications
