Triggering TypeError

How TypeError is raised and how to catch it.

python
# Triggering and catching TypeError
try:
    len(42)
except TypeError as e:
    print(f"Caught TypeError: {e}")
    print(f"Type: {type(e).__name__}")

TypeError is raised when raised when an operation is applied to an object of inappropriate type. Always catch specific exceptions rather than bare except clauses.

Handling TypeError

Basic error handling pattern for TypeError.

python
# Safe handling pattern
def safe_operation():
    try:
        len(42)
    except TypeError:
        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.
