"for" loops always need a variable (like "x") defined to iterate with different values. for x in range (7, 10): makes x to take values 7, 8, 9 and 10 successively and execute print(x) each time.

Question 5

The expression x in range (7, 16) makes x to take values from 7 up to 16 inclusive. So for each iteration it will execute print x*2 which prints the double of the actual value for x. Starting with x=7, it will print 14, then with x=8 will print 16, and so on. All values are shown on the table below:

X Prints

7 14

8 16

9 18

10 20

11 22

12 24

13 26

14 28

15 30

16 32

The code segments are illustrations of loops.

4: The first line should be for x in range(7,10):
5: The output is 14 16 18 20 22 24 26 28 30

The syntax of a for loop is:

for variable in range (begin,end+1):

The loop in question (4) is given as:

for range (7,10)

This means that, the variable is missing.

So, the first line of the code segment should be

for x in range(7,10):

For question 5, the value of x would range from 7 to 15.

The print statement prints twice x, followed by a space.

So, the output would be 14 16 18 20 22 24 26 28 30
