Drone Dispatch System

Figure 1 shows a grid representing a 3x3 landing zone system for a cargo drone delivery network.

Figure 1

Figure 2 shows an incomplete Python program designed to validate the user's landing zone input.

Figure 2

isValid = False
while isValid == False:
    zone = ""
    while len(zone) != 2:
        zone = input("Enter landing zone (e.g. L2): ")
        zone = zone.upper()

Extend the program from Figure 2 so it completes the other checks needed to make sure a valid landing zone code is entered.

The landing zone code is valid if:

• there are exactly two characters
• the first character entered is K, L, or M
• the second character entered is 1, 2, or 3

Your extended program must:

• use the variable isValid
• repeat the steps until a valid landing zone is entered
• output an appropriate error message if the zone code entered is not valid

You should use indentation as appropriate, meaningful variable names, and correct Python syntax in your answer.
