Which operator will return True if both the operands are true?
- and
- not
- or
- xor
The 'and' operator in Python returns True if both of its operands are true. It performs a logical AND operation. For example, True and True evaluates to True, while True and False evaluates to False.
When dealing with file I/O, the _______ statement is often used to ensure that the file is properly closed after its suite finishes.
- close
- open
- try-finally
- with

Given a scenario where a system should notify a user if the storage space goes below 5% or above 95%. Which of the following combinations of operators will be suitable for the condition?
- if storage < 5 or storage > 95:
- if storage <= 5 or storage >= 95:
- if storage > 5 and storage < 95:
- if 5 <= storage <= 95:
To check if the storage space goes below 5% or above 95%, you should use the condition if storage <= 5 or storage >= 95:. This condition covers both cases, ensuring that the system notifies the user when the storage falls below 5% or exceeds 95%. The other options do not provide the correct combination of operators for this scenario.
Which Python method is executed when the context of a with statement is entered?
- __enter__()
- __exit__()
