Answer:

The answer is "Option a"

Explanation:

Range-based for loop performs a sequence for a loop. It's more accessible as the conventional loop, for example, all components in the array, running more than a range of possibilities. In the given question "option a" is correct because it follows the correct syntax and other choices were wrong, which can be described as follows:

  • In option b, It's not correct, because in this code the range declaration is wrong.
  • In option c, It is wrong, because in this code the datatype is missing.  
  • In option d, It is illegal syntax, that's why it is wrong.

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integer
dalvyx [7]

Answer:

The program is as follows:

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

   for i in user_values:

       if i <= upper_threshold:

           print(i,end=" ")

           

def get_user_values():

   user_values = []

   n = int(input())

   for i in range(n):

       num = int(input())

       user_values.append(num)

   

   upper_threshold = int(input())

   output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold)

get_user_values()

Explanation:

This defines the output_ints_less_than_or_equal_to_threshold method

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

This iterates through user_values

   for i in user_values:

For every item in user_values

       if i <= upper_threshold:

This prints all items less than or equal to the upper threshold

           print(i,end=" ")

           

This defines get_user_values method

def get_user_values():

This creates an empty list

   user_values = []

This gets the number of inputs

   n = int(input())

This iterates through n

   for i in range(n):

This gets input for every item of the list

       num = int(input())

This appends the input to the list

       user_values.append(num)

This gets input for upper threshold    

   upper_threshold = int(input())

This calls output_ints_less_than_or_equal_to_threshold method

   output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold)

The main begins here; This calls get_user_values method

get_user_values()
