sqlalchemy.exc.OperationalErrorsqlalchemy.exc.OperationalError
A database operation failed due to a connection or database-level error.
ZeroDivisionErrorA division or modulo operation was attempted with zero as the divisor.
You divided a number by zero (x / 0, x // 0, or x % 0). This can happen when a variable that should never be zero turns out to be zero due to a logic error or unexpected input.
Add a check before dividing: if divisor != 0. Use try-except ZeroDivisionError. Validate inputs to ensure divisors are non-zero. Return a sensible default value when the divisor is zero.

BlockingIOErrorAn I/O operation would block on a non-blocking object.
TabErrorIndentation uses an inconsistent mix of tabs and spaces.
IOErrorAn I/O operation failed. IOError is an alias for OSError in Python 3.
