Write a function called 'average' that receives a list of numbers like parameter and return the average of those numbers. The list that receives the function must be entered by the user, but it must be validated that only numbers are entered. Whether enter a different value, the function should print 'ERROR' on the screen.

Complete the get_sum_of_evens (lower_bound, upper_bound) function that takes two integer parameters, lower bound and upper bound. The function returns the sum of all the even numbers between the two bounds, both included, passed to the function. You can assume that lower bound will always be smaller than or equal to upper_bound. For example: Test result get sum_of_evens (2, 4) print("The sum of all even numbers are:", result) print (get_sum_of_evens (9, 17)) Result The sum of all even numbers are: 6 52
Common Time Zones Function Name: commonTimeZones() Parameters: code1( str ) , code2( str ) Returns: list of common time zones ( list ) Description: You and your friend live in different countries, but you figure there's a chance that both of you might be in the same time zone. Thus, you want to find out the list of possible time zones that you and your friend could both be in. Given two country codes, write a function that returns a list of the time zones the two countries have in common. Be sure not to include any duplicate time zones. If the two country codes do not have any common time zones, return the string 'No Common Time Zones' instead. Note: You can assume that the codes will always be valid. example test cases: >>> commonTimeZones('can', 'usa') ['UTC-08:00', 'UTC-07:00', 'UTC-06:00', 'UTC-05:00', 'UTC-04:00'] >>> commonTimeZones('rus', 'chn') ['UTC+08:00'] For this assignment, use the REST countries API…
A prime number is an integer value that is only divisible by 1 and itself. 2, 3, 5, 7, and 11 are examples of prime numbers. You have been provided with two function definitions: The is_prime () function takes an integer parameter number, and returns True if number is prime and False otherwise. The get_next_prime () function also takes a single integer parameter number, and returns the first prime number larger than it. You must not change the implementation of these 2 functions. Complete the get_primes_list() function that takes a single list of integers called numbers as parameter. You can assume that the integer items in this list will be non-negative. The function must update this list so that items that are not prime numbers are updated to the first prime number larger than them. To implement this function you must call both the is_prime () and get_next_prime () functions. Some examples of the function being called are shown below. Note: the get_primes_list() function does not…

that takes 3 integers as an input from the user and display them in ascending order (slai y ). For example, if the input is 2, 3 and 1, this program should display 1, 2 and Write program a 3. To resolve this problem, you should write 3 void functions: inputNumbers, sortNumber and displayNumbers. inputNumbers : the aim of this function to read 3 numbers from the user. sortNumber : the aim of this function to sort three numbers. displayNumbers : print the results. easy code
ii. Add a function named count_all() to this program that takes two parameters, a list of characters (e.g., x) and a character (e.g., y), in this order. This function must return the total number of times y appears in x. You must NOT use the built-in count() method to solve this problem.
5. A prime number is a number that is only evenly divisible by itself and 1. For example, the number 5 is prime because it can only be evenly divided by 1 and 5. The number 6, how- ever, is not prime because it can be divided evenly by 1, 2, 3, and 6. Write a Boolean function named is_prime which takes an integer as an argument and returns true if the argument is a prime number, or false otherwise. Use the function in a program that prompts the user to enter a number then displays a message indicating whether the number is prime. 6. In another program, use the function you wrote in question 5 to print the prime numbers between 1 and 100 using for loop.
In C++ write a program that generates three random numbers and then find the min number among the generated values, using these three functions: void getrandnum(int &n1, int &n2, int &n3), int findMin(int n1, int n2, int n3), and void printResult(int n1, int n2, int n3, int min). Make the main function drive all these functions.
Write a function called substring that uses the leftmatch and rightmatch functions to remove a pattern from the left and right side of a value. It should take three arguments as shown: $ substring /usr/ /usr/spool/uucppublic /uucppublic spool $ substring s. s.main.c .c main $ substring s. s.main.c .o Only left match main.c $ substring x. s.main.c .o No matches s. main.c
Q2: Write a function that, when you call it, displays a message telling how many times it has been called: “I have been called 3 times", for instance. Write a main() program that calls this function at least 10 times. HInt: use a global variable to store the count
please code in python Assume you own a small cafeteria with very limited menu and you want to automate the orders. You have a list of menu items, a list with the price of these items. The number of elements in both lists should be the same. The program then asks the customer how many elements he wants from each item, then it should summarize the order of the customer and announce the price to pay. You can use the function from the previous exercise to check that the user enters a non-negative quantity each time.Assuming that we have:MENU_ITEMS=['karak','tea','coffee']PRICE_LIST=[2,1,5]You should get a sample run similar to that:How many karak do you want? 3How many tea do you want? 2.5Please enter valid quantity.How many tea do you want? -2Please enter valid quantity.How many tea do you want? 0How many coffee do you want? 1Your order is: - 3 karak - 0 tea - 1 coffeeYour total bill is 11 QAR.
