Question

Selector

Answer 1

Answer:

See explaination

Explanation:

# Import required the module.

import random

# Define a function selector() which accepts the

# input_list, check_list, and return_list and

# returns a string named output.

def selector(input_list,check_list,return_list):

# Assign None to string variable output.

output=None

# Use for loop to traverse through input_list.

for i in range(len(input_list)):

# Check if element of an input_list is present

# in check_list.

if input_list[i] in check_list:

# Assign a random value from return_list

# to output.

output=random.choice(return_list)

# break out of the loop if input_list

# element is present in check_list.

break

#

return output

# Use assert statement to test a condition.

# If the condition is true, then program continues to

# execute, otherwise raises an AssertionError.

assert callable(selector)

assert selector(['is','in','of'],['of'], ['Yes']) == 'Yes'

assert selector(['is','in'],['of'], ['Yes','No']) == None

# Display the output.

print(selector(['is','in','of'],['of'], ['Yes']))

print(selector(['is','in'],['of'], ['Yes','No']))
