Answer: option b

Explanation:

The global keyword inside the my_function function indicates that the variable x refers to the global variable with the same name. The function increments the global variable x by 1, so its new value is 6.

19.		What is the output of the following code? def my_function(x, y):return x ** y result = my_function(2, 3) print(result)

A. 5

B. 8

C. 6

D. 1

Answer: option b

Explanation:

The ** operator is used to calculate the power of a number. The my_function function takes two arguments x and y, and returns x raised to the power of y. In this case, 2 raised to the power of 3 is 8.

20.		What is the output of the following code? def my_function(x, y=2):return x ** y result1 = my_function(2) result2 = my_function(2, 3) print(result1, result2)

A. 2 8

B. 4 8

C. 4 6

D. 2 6

Answer: option b

Explanation:

The my_function function takes two arguments x and y, with a default value of 2 for y. If only one argument is passed, y takes the default value. The function returns x raised to the power of y. In this case, result1 is 2 raised to the power of 2, which is 4, and result2 is 2 raised to the power of 3, which is 8.
