• prints the sequence less than 50, increasing by 3 each time.

• prints the sequence outside 50, summing the elements of the sequence.

• prints the sequence three times the sequence of 50.

What is the result of the following program: for k in range(10): print(k,end= “ ”) if k==5: break

• 0,1,2,3,4,5

• 0,1,2,3,4,5,6,7,8,9

• 0,1,2,3,4,5,6,7,8,9,10

What is the command to get the length of the list K?

• len(K)

Given the list H=[5,7,9,6,4], what is the command to access the element with the value 9 in that list H?

• H[2]

• H[3]

• H[9]

• H(2)

In a list, we can access each element of the list through:

What is the meaning of the following command: H=[1,2,3,4] for k in H: print(k)

• prints each element of the list H.

• prints each position of the list H.

• prints the sequence of characters k.

• prints from 0 to the length of the list minus 1.
