Loops

Question 1

While Loop

Answer 1

This is a loop that will keep repeating itself until the while condition becomes false.

n = 1
while n < 100:
n += 1

Question 2

For Loop

Answer 2

For loops give you more control than while loops. You can loop through a range, a list, a dictionary, or a tuple.

all_fruits = [“apple”, “banana”, “orange”]
for fruit in all_fruits:
print(fruit)

Question 3

_ in a For Loop

Answer 3

If the value your for Loop is iterating through, ex: the number in the range, or the item in the list is not needed, you can replace it with an underscore.

for _ in range(100):
#Do something 100 times.

Question 4

break

Answer 4

This keyword allows you to break free if the loop. You can use it in a for or while Loop.

for s in scores:
if s > 100/:
print(“Invalid”)
break
print(s)

Question 5

continue

Answer 5

This keyword allows you to skip this iteration of the loop and go to the next. The loop will still continue, but it will start from the top.

n = 0
while n < 100:
n += 1
if n % 2 == 0:
continue
print(n)
#Prints all the odd numbers
