The correct answer is: C. both (a) and (b)
The >> (extraction)
operator stops reading characters from the keyboard as soon as the user presses the Enter key or types a character that is inappropriate for the variable’s data type.For example, if we have a variable x of type int, and we try to extract a character from the keyboard using the following code:
x = input('Enter a number: ')
The user will be able to enter any character,
but as soon as they press the Enter key, the extraction will stop and the value ofx will be the number that the user entered.
However, if the user types a character that is not a number, such as a letter or a symbol, the extraction will stop and the value of x will be None.
Here is an example of this:
x = input('Enter a number: ')
print(x)
If the user enters the number 123, the output will be 123. However, if the user enters the letter a, the output will be None.
