Question

question: 15
which of the following inputs to the program below would print a statement containing your number:
try:
my_number = int(input(\enter an integer: \))
print(\your number: \ + str(my_number))
except valueerror:
print(\that wasnt an integer!\)
four
5
3.0
*

Explanation:

Step1: Analyze the code

The code tries to convert the input to an integer. If successful, it prints "Your number: [number]". If not (ValueError), it prints "That wasn't an integer!".

Step2: Check each option

• Option "Four": int("Four") will raise a ValueError as "Four" is not a valid integer representation.
• Option "5": int("5") is valid. my_number = 5, then print("Your number: " + str(5)) which contains "Your number".
• Option "3.0": int("3.0") raises a ValueError because int conversion of a string with a decimal point (when it's not in a valid float - to - integer conversion context like in some other languages) is not allowed in Python (it expects a string of digits for direct int conversion from a string).
• *Option ""*: int("") raises a ValueError as "*" is not a digit.
