Question:
Which of the following operator evaluates to True if the variable on either side of the operator points towards the same memory location and False otherwise?
Which of the following operator evaluates to True if the variable on either side of the operator points towards the same memory location and False otherwise?
Show Hint
Use is to check if two variables are the same object,
and use == to check if their values are equal.
This is important when comparing mutable objects like lists or custom classes.

The Correct Option is A
Solution and Explanation
In Python, the is operator checks for object identity,
which means it returns True if two variables point to the same memory location.
This is different from the equality operator == which checks if the values are the same.
For example, two identical lists may have equal values but not the same identity.
The is not operator checks for the opposite — it returns True if the variables do not share the same identity.
The and and or operators are logical operators and do not check memory locations.
Therefore, the operator that checks if both variables refer to the same object in memory is is.
So, the correct answer is option (A).

PASSENGERS.DATstores the records of passengers using the following structure:
PNR, PName, BRDSTN, DESTN, FARE
Where:
- PNR — Passenger Number (string type)
- PName — Passenger Name (string type)
- BRDSTN — Boarding Station Name (string type)
- DESTN — Destination Station Name (string type)
- FARE — Fare amount for the journey (float type)
Write user-defined functions in Python for the following tasks:
(i)Create()– to input data for passengers and write it in the binary filePASSENGERS.DAT.
(ii)SearchDestn(D)– to read contents from the filePASSENGERS.DATand display the details of those Passengers whose DESTN matches with the value ofD.
(iii)UpdateFare()– to increase the fare of all passengers by 5% and rewrite the updated records into the filePASSENGERS.DAT.

- A stack, named ClrStack, contains records of some colors. Each record is represented as a tuple containing four elements — ColorName, RED, GREEN, BLUE. ColorName is a string, and RED, GREEN, BLUE are integers. For example, a record in the stack may be
('Yellow', 237, 250, 68).
Write the following user-defined functions in Python to perform the specified operations on ClrStack:
(i)push_Clr(ClrStack, new_Clr): This function takes the stack ClrStack and a new record new_Clr as arguments and pushes this new record onto the stack.
(ii)pop_Clr(ClrStack): This function pops the topmost record from the stack and returns it. If the stack is already empty, the function should display the message "Underflow".
(iii)isEmpty(ClrStack): This function checks whether the stack is empty. If the stack is empty, the function should return True, otherwise the function should return False.
