Triggering ResourceWarning

How ResourceWarning is raised and how to catch it.

python
# Triggering and catching ResourceWarning
try:
    import warnings; warnings.warn("resource issue", ResourceWarning)
except ResourceWarning as e:
    print(f"Caught ResourceWarning: {e}")
    print(f"Type: {type(e).__name__}")

ResourceWarning is raised when warning about resource management issues. Always catch specific exceptions rather than bare except clauses.

Handling ResourceWarning

Basic error handling pattern for ResourceWarning.

python
# Safe handling pattern
def safe_operation():
    try:
        import warnings; warnings.warn("resource issue", ResourceWarning)
    except ResourceWarning:
        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.
