Triggering TabError

How TabError is raised and how to catch it.

python
# Triggering and catching TabError
try:
    exec("if True:\n\t x = 1\n  y = 2")
except TabError as e:
    print(f"Caught TabError: {e}")
    print(f"Type: {type(e).__name__}")

TabError is raised when raised when tabs and spaces are mixed inconsistently. Always catch specific exceptions rather than bare except clauses.

Handling TabError

Basic error handling pattern for TabError.

python
# Safe handling pattern
def safe_operation():
    try:
        exec("if True:\n\t x = 1\n  y = 2")
    except TabError:
        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.
