11.
How can you stop the execution of a generator prematurely?
Raise a StopIteration exception
Use the break statement
Call the stop() method on the generator
Return from the generator function
Answer: Option
Explanation:
To stop the execution of a generator prematurely, you can use the break statement within the generator function. This will exit the generator's loop.
12.
What is the purpose of the itertools.count() function when used with generators?
It creates an infinite sequence of numbers
It counts the number of elements in a generator
It initializes the generator function
It generates random numbers
Answer: Option
Explanation:
itertools.count() generates an infinite sequence of numbers, starting from a specified value. When used with generators, it can create an infinite sequence of numbers for iteration.
13.
In a generator function, what does the return statement without a value indicate?
It terminates the generator function with an empty result
It restarts the generator from the beginning
It raises a StopIteration exception
It is not a valid syntax in a generator function
Answer: Option
Explanation:
In a generator function, a return statement without a value indicates that the generator has reached the end of its execution and will terminate with an empty result.
14.
How can you implement a conditional expression within a generator expression?
Using the if statement
Using the while loop
Using the switch keyword
Using the if keyword within parentheses
Answer: Option
Explanation:
Conditional expressions within a generator expression can be implemented using the if statement. This allows you to include or exclude elements based on a specified condition.
15.
How can you pass a value to a generator function from the outside?
Using the send() method
Using the pass_value() function
By modifying the generator function's arguments
It is not possible to pass values to a generator function
Answer: Option
Explanation:
The send() method allows you to pass a value to a generator function from the outside. This value becomes the result of the yield expression.
