Question

Which of the following print statements are valid (would work without error) given the following two variables?: score =35, total =50​. Hint: The variables contain integers, and some of the print statements involve concatenation. print ('You scored', score, 'out of', total) print ('You scored' + score + ' out of ' + total) print ('You scored' + str(score) + ' out of ' + str(total)) print('You scored' score 'out of' total).

Answer 1

Only the first and third print statements provided are valid. The first uses commas correctly, and the third properly converts integers to strings before concatenation. The second and fourth statements are invalid due to improper concatenation and syntax errors.

Step-by-step explanation:

The student has provided two variables score = 35 and total = 50, both of which are integers. When working with print statements in Python, concatenation of strings with integers is not allowed directly, as it will cause a TypeError. Instead, we need to convert the integers to strings using the str() function.

• print ('You scored', score, 'out of', total) - This is a valid print statement because it uses commas to separate items, and Python will automatically convert the integers to strings.
• print ('You scored' + score + ' out of ' + total) - This is not valid because it attempts to concatenate strings with integers directly.
• print ('You scored' + str(score) + ' out of ' + str(total)) - This is a valid print statement because it converts the integers to strings before concatenation.
• print('You scored' score 'out of' total) - This is not valid because it lacks the necessary commas or plus signs for separation and does not convert the integers.

Hence, the first and third print statements are valid and would work without error.
