In PYTHON, when copying "LISTS", what is the difference between the following: first_list =new_list[:] versus first_list = new_list What would be the better code so that if I make a change in 'first_list', the changes will also reflect 'new_list' and vice versa?

- Using Python This assignment is about temperatures and requires the main function and a custom value-returning function. The value-returning function takes a list of random Fahrenheit temperatures as its only argument and returns a smaller list of temperatures that are below freezing. The main function needs these steps in this sequence: create an empty list that will the hold Fahrenheit temperatures. use a loop to add 25 random integertemperatures to the list. All temperatures should be between 5 and 75, inclusive. use another loop to display all 25 temperatures on one line separated by spaces. report the highest and lowest temperatures in the list. 32 might be in the list. Report the index of the first instance of 32 or report that it didn't make the list. using slice syntax: print the first 10 temperatures in the list. print the middle 5 temperatures in the list. print the final 10 temperatures in the list. execute the custom value-returning function with the complete list as…Using Python This assignment is about temperatures and requires the main function and a custom value-returning function.

Write a function called "zero_triples" to return all triples in a list of integers that sum to zero.

- HELP PYTHON Write a program that takes a list of S integers and performs the following functions. Create two functions, and each function takes a single parameter my_list, which is a Python list: delete_prime(my_list) - returns a list with all prime numbers removed. The function returns a new list, and the parameter input my_list is not modified. Input: list Return value: list reverse_list(my_list) - reverses my_list. The parameter input my_list is modified. Input: list Return value: None Notes: Since a list is a mutable object, you may need to make a copy of the original list to pass as input parameter to the function. Modern mathematicians define a number as prime if it is divided by exactly two numbers. To keep things simple for this exercise, assume all elements of the list have a value greater than 1. Constraint: You are not allowed to use my_list[::-1], my_list.reverse(), or reversed(my_list). Input Format Assume the inputs are integers. The first line contains the…in python Integer num_samples is read from input, representing the number of data samples to be read from input. List data_list contains the data samples read from the remaining input. For each element in data_list: If the element is greater than 25, output the element followed by ' at index ', the element's index in the list, and ' is flagged'. Otherwise, output the element followed by ' at index ', the element's index in the list, and ' is normal'.Code in python Given a list, L, the function front_two creates a new list of length 2 out of the first two items in L as follows: In the new list, the second item becomes the first item, and the first item becomes the second. If L contains only one item, the first item in the new list should be the value None. If L is empty, both items in the new list should be value None. The function returns the new list. For example: Test Result L = ['a', 'b', 'c', 'd'] print(front_two(L)) ['b', 'a'] L = [] print(front_two(L)) [None, None] L = [5, 2] print(front_two(L)) [2, 5] L = [7] print(front_two(L)) [None, 7]
- Can I get some help writing this? Write a Python program that counts the number of words in a list that have a minimum length. The list and the minimum length will be entered by the user. Your program should contain one function: (1) min_len_count(word_list, min_length): This function takes in two parameters, a word_list as a list of words and min_length as the minimum word length (integer). This function will loop over the list elements and return the total number of words in the list that have a length greater than or equal to min_length. Hint: This function should not contain any print statement. (2) Outside the function, your program should do the following: a. Prompt the user to enter 4 string elements and add them to a list called word_list. (Use a for loop) b. Prompt the user to enter an integer value called min_length. c. Call the function min_len_count(word_list, min_length) with two arguments: word_list, min_length d. Print the output that the function returns.Using Python: This assignment requires the main function and a custom value-returning function. The value-returning function takes a list of random Fahrenheit temperatures as its only argument and returns a smaller list of only the temperatures above freezing. This value-returning function must use a list comprehension to create the list of above freezing temperatures.In the main function, code these steps in this sequence: create an empty list that will the hold random integer temperatures. use a loop to add 24 random temperatures to the list. All temperatures should be between 10 and 55, inclusive. Duplicates are okay. sort the list in ascending order. use another loop to display all 24 sorted temperatures on one line separated by spaces. 32 could be in the list. If it is, report the index of the first instance of 32. if 32 isn't in the list, add it at index 4. assign a slice consisting of the first six temperatures to a new list. Then print it. execute the custom value-returning…The function swap_list_ends in python takes one parameter, L, which is a list. The function then swaps the first and last items in L and returns the object None. Notice that since L is mutable, the changes the function makes to L are visible back in the calling program. SPECIAL CASE: If the list 'L' is empty, then the function does nothing to L and returns None. For example: Test Result L = [1, 3, 9, 2] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [2, 3, 9, 1] L = ['super', 'awesome', 'excellent'] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) ['excellent', 'awesome', 'super'] L = [True, False] if not(swap_list_ends(L) is None): print("Error: function should return None") print(L) [False, True]
- Need help with python problem Create two lists of your friends that you found in 2017 and 2018. For example: friends_2017 = ["Joe", "Lily"] friends_2018 = ["Bob", "Tom"] Concatenate the two lists and then show (print) them to the user. Ask the user to enter a name of a friend. Then show that you found the friend in 2017 or 2018, or they don't have any friend with this name in their friends' list. Ask the user to enter a new friend name to be added to the 2017 or 2018 lists (Also, you need to ask the user what year they want to add the friend name). Then append the entered friend name to the related list (2017 or 2018 friend lists) Print the 2017 friends list and also the 2018 friends list on the screen. For this exercise, you don't need to check the user inputs. Also, you don't need to use loops. Put at least two outputs (results after you run your code) at the end of your code as a multi-line comment. Don't forget to put your name and a short description of…The Python function fourthMultLast below should take a list of numbers as input and return the sum of the third element and the last element of the list.
