Question

Write python logical expressions for the following:

i) Flight name is Gulf Air and Flight No. is in between 1100 to 2200.
A) (FlightName == "Gulf Air") and (1100 <= FlightNo <= 2200)
B) (FlightName == "Gulf Air") or (1100 <= FlightNo <= 2200)
C) (FlightName != "Gulf Air") and (1100 <= FlightNo <= 2200)
D) (FlightName != "Gulf Air") or (1100 <= FlightNo <= 2200)

ii) Number is either less than 5 or less than 7, but not 2.
A) (Number < 5) or (Number < 7) and (Number != 2)
B) (Number < 5) and (Number < 7) and (Number != 2)
C) (Number < 5) or (Number < 7) or (Number != 2)
D) (Number < 5) and (Number < 7) or (Number != 2)

Answer 1

i) The python logical expressions for "Flight name is Gulf Air and Flight No. is in between 1100 to 2200" is A) (FlightName == "Gulf Air") and (1100 <= FlightNo <= 2200)

ii) The python logical expressions for "Number is either less than 5 or less than 7, but not 2" is A) (Number < 5) or (Number < 7) and (Number != 2)

Step-by-step explanation:

i) Python logical expressions for flight name is Gulf Air and Flight No. is in between 1100 to 2200.

• A) (FlightName == "Gulf Air") and (1100 <= FlightNo <= 2200): This is the correct expression. It checks both conditions: FlightName being "Gulf Air" and FlightNo being between 1100 and 2200.
• B) (FlightName == "Gulf Air") or (1100 <= FlightNo <= 2200): This is incorrect. It only needs one condition (flight name or flight number) to be valid for the expression to be true.
• C) (FlightName != "Gulf Air") and (1100 <= FlightNo <= 2200): This is incorrect. It checks for the opposite of the flight name condition and the flight number range.
• D) (FlightName != "Gulf Air") or (1100 <= FlightNo <= 2200): This is incorrect. It allows either the opposite of the flight name condition or the flight number range to be true.

ii) Python logical expressions for number is either less than 5 or less than 7, but not 2.

• A) (Number < 5) or (Number < 7) and (Number != 2)**: This is the correct expression. It checks for either number being less than 5 or 7, but excludes the number 2.
• B) (Number < 5) and (Number < 7) and (Number != 2)**: This is incorrect. It requires the number to be less than both 5 and 7, which is unnecessary.
• C) (Number < 5) or (Number < 7) or (Number != 2)**: This is incorrect. It allows any of the conditions to be true, which includes the number being 2.
• D) (Number < 5) and (Number < 7) or (Number != 2)**: This is incorrect. It requires the number to be less than both 5 and 7, and then allows the number to be 2, which is contradictory.

Correct answer:

• i. A) (FlightName == "Gulf Air") and (1100 <= FlightNo <= 2200)
• ii. A) (Number < 5) or (Number < 7) and (Number != 2)
