Triggering FileNotFoundError

How FileNotFoundError is raised and how to catch it.

python
# Triggering and catching FileNotFoundError
try:
    open("nonexistent_file.txt")
except FileNotFoundError as e:
    print(f"Caught FileNotFoundError: {e}")
    print(f"Type: {type(e).__name__}")

FileNotFoundError is raised when raised when trying to open a file that doesn't exist. Always catch specific exceptions rather than bare except clauses.

Handling FileNotFoundError

Basic error handling pattern for FileNotFoundError.

python
# Safe handling pattern
def safe_operation():
    try:
        open("nonexistent_file.txt")
    except FileNotFoundError:
        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.
