Question
Written #2
2A
Which of the following two options will correctly prompt the user until they enter a valid
weekend day?
# Option 1
SAT = "Sat"
SUN = "Sun"
day = input("Which day is better for brunch?\n")
while day != SAT and day != SUN:
day = input("Sorry, what? Please enter a valid day.\n")
print("Thank you!")
# Option 2
SAT = "Sat"
SUN = "Sun"
day = input("Which day is better for brunch?\n")
while day != SAT or day != SUN:
day = input("Sorry, what? Please enter a valid day.\n")
print("Thank you!")
2B
For the option above that doesn't work (i.e., it doesn't successfully detect a valid weekend day), is the problem that...
1. It thinks bad inputs (like "Mon") are valid.
2. It thinks good inputs (like "Sat") are invalid.

Expert Solution
Step 1

Question 2A:

Since the given inputs are 

SAT = "Sat"

SUN = "Sun"

The input will be only valid when we enter only Sat and Sun

the while condition : while day!=SAT and day != SUN: will check for both Sat and Sun and will return if it is true either it will again ask for input.
