NEW QUESTION # 43
Which keyword is used to exit a loop prematurely in Python?
Answer: C
Explanation:
The break keyword exits a loop immediately before the loop condition naturally becomes false or before all items have been processed.
Example:
for number in range(10):
if number == 5:
break
print(number)
When number becomes 5, the loop stops. Python's control-flow documentation explains the use of break in loops.
Therefore, the correct answer isB. break.
NEW QUESTION # 44
Fix the missing return statement in this function that should return whether a number is even.
def is_even(number):
if number % 2 == 0:
True
else:
False
Answer:
Explanation:
See the Step by Step Solution below in Explanation.
Explanation:
Step 1: The expression number % 2 == 0 checks whether the number is even.
Step 2: The original code writes True and False, but it does not return them.
Step 3: A function must use the return statement to send a value back to the caller.
Correct code:
def is_even(number):
if number % 2 == 0:
return True
else:
return False
Simplified correct code:
def is_even(number):
return number % 2 == 0
Example:
print(is_even(4))
print(is_even(7))
Output:
True
False
NEW QUESTION # 45
Which keyword moves a loop immediately to its subsequent iteration?
Answer: C
Explanation:
The Python keyword continue is used inside a loop to skip the rest of the current iteration and move immediately to the next iteration.
Example:
for number in range(5):
if number == 2:
continue
print(number)
Output:
0
1
3
4
When number is 2, the continue statement skips print(number) for that iteration and moves to the next loop cycle.
The official Python documentation states that the continue statement continues with the next iteration of the loop.
Therefore, the correct answer is C. continue.
NEW QUESTION # 46
Which type of loop is designed for iterating a specific number of times?
Answer: D
Explanation:
A for loop is commonly used when a program needs to repeat code for each item in a sequence or for a specific number of times using range().
Example:
for number in range(5):
print(number)
This loop runs 5 times. Python's documentation explains that the for statement iterates over items of a sequence or iterable.
Therefore, the correct answer isB. for loop.
NEW QUESTION # 47
Complete the function update_grade(grades, student, new_grade) that takes a grades dictionary, a student name, and a new grade, then updates that student ' s grade and returns the dictionary.
For example, update_grade({ " Alice " : 85, " Bob " : 90}, " Alice " , 95) should return { " Alice " : 95, " Bob
" : 90}.
Answer: C
Explanation:
A dictionary stores data as key-value pairs. In this function, the student name is the key, and the grade is the value.
Correct code:
def update_grade(grades, student, new_grade):
grades[student] = new_grade
return grades
Example:
update_grade({ " Alice " : 85, " Bob " : 90}, " Alice " , 95)
Result:
{ " Alice " : 95, " Bob " : 90}
Python's built-in types documentation includes dictionaries as mapping types, where values are accessed and updated using keys.
Therefore, the correct answer isA.
