Question

question: 14
what line of code should be written after the function definition to add two single - digit values and print the sum?
def get_single_digit():
while true:
try:
num = int(input(\enter a single - digit positive number: \))
if num > 9:
print(
umber must be less than 10\)
elif num < 0:
print(
umber must be positive.\)
else:
return num
except valueerror:
print(\that isnt a number!\)

print(get_single_digit() + get_single_digit())
return get_single_digit() + get_single_digit()
print(get_single_digit(4) + get_single_digit(5))
print(get_single_digit()++)

Explanation:

• The function get_single_digit() is designed to get a single - digit positive number from the user.
• To add two such numbers and print the sum, we need to call the function twice (to get two numbers) and then add them. The print() function is used to display the result.
• Option 2: return is used inside a function to send a value back. But we are not in a function context here (we are after the function definition), so this is incorrect.
• Option 3: Passing 4 and 5 as arguments to get_single_digit() is wrong because the function is designed to get user input, not take arguments.
• Option 4: ++ is not a valid operator in Python for incrementing in this context.

Answer:

print(get_single_digit() + get_single_digit())
