Triggering GeneratorExit

How GeneratorExit is raised and how to catch it.

python
# Triggering and catching GeneratorExit
try:
    raise GeneratorExit("generator closed")
except GeneratorExit as e:
    print(f"Caught GeneratorExit: {e}")
    print(f"Type: {type(e).__name__}")

Handling GeneratorExit

python
# Safe handling pattern
def safe_operation():
    try:
        raise GeneratorExit("generator closed")
    except GeneratorExit:
        print("Operation failed gracefully")
        return None

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

Wrapping risky operations in try/except blocks prevents your program from crashing.
