Question

What possible output from the given options is expected to be displayed when the following Python code is executed?

import random 
Signal = ['RED', 'YELLOW', 'GREEN'] 
for K in range (2, 0, -1): 
R = random.randrange (K) 
print (Signal [R], end = '#') 

पर्याय

• YELLOW # RED #

• RED # GREEN #

• GREEN # RED #

• YELLOW # GREEN # 

Answer 1

YELLOW # RED #

Explanation:

The numbers 2, 1 can be assumed by the variable K. In the first iteration, R can have values of 0,1; hence, "RED" or "YELLOW" can be the values of Signal [R]. Signal [R] may have the value "RED" since the possible values for R in the second iteration are 0.
