Triggering BlockingIOError

How BlockingIOError is raised and how to catch it.

python
# Triggering and catching BlockingIOError
try:
    raise BlockingIOError("blocking I/O")
except BlockingIOError as e:
    print(f"Caught BlockingIOError: {e}")
    print(f"Type: {type(e).__name__}")

BlockingIOError is raised when raised when a non-blocking i/o operation would block. Always catch specific exceptions rather than bare except clauses.

Handling BlockingIOError

python
# Safe handling pattern
def safe_operation():
    try:
        raise BlockingIOError("blocking I/O")
    except BlockingIOError:

        return None

result = safe_operation()
print(f"Result: {result}")
