KP4-Loops

What would be the lowest value printed by this code?

for i in range(12):

print(i)

• 12

• 0

• None of these

• 1

What is the value of the variable 'a' after it passes through the loops?

a = 0

for i in range(2):

for j in range(4):

a += i * j

• 10

• 4

• 6

• 8

What is the value of the variable 'a' after it passes through the loops?

a = 0

for i in range(2):

for j in range(3):

a += i + j

• 8

• 9

• 10

• 3

***Add the line of code needed to accumulate the total of all values of a and then print the result.

total=0

for a in range(6):

#what goes here?

print(total)

• total = total +a

• total = a +1

• total += a

• total =+a

****You are given a function which contains a non working while loop. The function also accepts a positive integer (x). The while loop is in an infinite loop state, which would be unwise to run. The while loop continually decreases the value variable by 1. Your task is to fix the code so that the loop exits and returns the value variable when it is equal to x.

def while_loop_finisher:

value = -1

while value:

value -=1

• if value == x:

  return x

  break

• if value == 1:

  return value

  break

• if value = x:

  return x

  break

• if x == value:

  return x

  break

What is the purpose of the break statement in Python?

• Skip the remainder of the if body and transfer control to the if condition

• Terminate the loop and transfer control to the statement following the loop

• Skip the remainder of the loop body and transfer control to the loop condition

• Terminate the if statement and transfer control to the statement following the if

What does the “continue” Statement in Python do?

• it terminates the execution of statements while iterating the loop

• it breaks the loop

• None of these

• it does not break the loop

****Add the line of code needed to count the number of values generated for a and then print the result.

count = 0

for a in range(6)

# code goes here

print (count)

• count = count + a

• count = a+ 1

• count += 1

• count =+ 1

***Write a function that accepts two integers(a and b, where a < b) and returns the sum of all numbers between a and b (inclusive of a and b).

def looping_sum:

• return sum (range(a,b+1)

• return sum(range(a,b+1))

• return sum (range(a,b))

• return sum(a,b)

****Write a function that iterates over a tuple(tup) and returns the position of the first odd number.

def return_position_of_odd:

• for num in tup:

  if num%2==1:

  return tup.index(num)

• for num in range(len(tup)):

  if tup[num]%2==1:

  return num

• for num in tup:

  if num%2==0:

  return tup.index(num)

• for num in range(len(tup)):

  if tup[num]%2==0:

  return num
