Triggering RuntimeError

How RuntimeError is raised and how to catch it.

python
# Triggering and catching RuntimeError
try:
    raise RuntimeError("runtime error occurred")
except RuntimeError as e:
    print(f"Caught RuntimeError: {e}")
    print(f"Type: {type(e).__name__}")

RuntimeError is raised when raised when an error doesn't fit any other category. Always catch specific exceptions rather than bare except clauses.

Handling RuntimeError

Basic error handling pattern for RuntimeError.

python
# Safe handling pattern
def safe_operation():
    try:
        raise RuntimeError("runtime error occurred")
    except RuntimeError:
        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.
