Question

Which of the following range functions would give the following sequence:

8, 5, 2

		range(8,2)
		range(2,10,3)
		range(8,1,-3)
		range(8,3,-2)

hat is the result of the following expression, assume x = 5?

((x <= 5) and (x!=0))

		False
		Syntax error
		True
		5

What statement is used to exit out of a loop?

		pass
		continue
		break
		exit

Which of the following is not a Python logical operator?

		not
		and
		or
		nor

Answer 1

SOL:

1) The range functions which give the sequence 8,5,2 is

range(8,1,-3)

so option 3rd is correct

Explanation:

range(8,1,-3) says that it gives the numbers from 8 to 1 with an offset of -3

First it will given 8

next it will give 8-3 = 5

next it will give 5-3 = 2

next 2-3 = -1 so -1 is not in range of 8 to 1 so it will stop there

so range(8,1,-3) is correct

2) TRUE

Explanation:

Given x=5

The expression is ((x<=5) and (x!=0))

The First one is x<=5 --> 5<=5 is TRUE because 5 is equal to 5 here

and next one x!=0 ---> 5!=0 is TRUE because 5 is not equal to 0

so TRUE and TRUE = TRUE

so The answer is TRUE

3) Break is the correct answer

Explanation:

Break statement is used to exit from the Loop

4) nor is not a python logical operator

so option 4 is correct

Explanation:

ALL three operators and,or, not are used as logical operators in python but nor is not used
