Introduction to Python - Loops and Logic

How many numbers does this code output?
x = 0

while x < 8:

print(x)

x +=1

• The numbers from 0 to 7

• The numbers from 0 to 8

• The numbers from 1 to 8

• The numbers from 1 to 7

How many stars does this code output?

for i in range(5):

print("*")

• 1

• 2

• 4

• 5

What is missing in this code for it to work properly?

x=0

while x < 5:

print(x)

• x + 1

• x += 1

• x

• +1

Which line makes this an infinite loop?

x = 6

while True:

print(x)

if x == 4:

break

x+=1

• x+=1

• break

• while True

• x == 4

Answer explanation

A while loop runs as long as the condition it has is true, in this case True can never be false, so the line that makes it INFINITE (it runs forever) is:

while True

What type of loop is a for loop?

• a conditional loop

• a counter controlled loop

• a variable

• a number

What type of loop is a while loop?

• a counter controlled loop

• a variable

• a letter

• a conditional loop

How many numbers will this loop print?

for i in range(1,7):

print(i)

• Numbers 1 to 6

• Numbers 0 to 7

• Numbers 1 to 7

• Numbers 1 to 8

What does this output?

x = True

print(not x)

• False

• True

What does this output?

x = True

y = False

print(x and y)

• False

• True

What does this output?

x = True

y = False

print(x or y)

• True

• False
