USING PYTHON, write a function that takes a list of integers as input and returns a list with only the even numbers in descending order (Largest to smallest)

Example: Input list: [1,6,3,8,2,5] List returned: [8, 6, 2].

DO NOT use any special or built in functions like append, reverse etc.

source code:


def bubbleSort(arr):
n = len(arr)
  
# Traverse through all array elements
for i in range(n-1):
# range(n) also work but outer loop will repeat one time more than needed.
  
# Last i elements are already in place
for j in range(0, n-i-1):
  
# traverse the array from 0 to n-i-1
# Swap if the element found is greater
# than the next element
if arr[j] < arr[j+1] :
arr[j], arr[j+1] = arr[j+1], arr[j]
  
def even(l):
for i in l:
if(int(i)%2==1):
l.remove(i)
bubbleSort(l)
return l


print(even( [1,6,3,8,2,5] ))

1.Write a function div7(lst) which takes in a list of integers, and returns a list of booleans of the same length, such that for each integer in the original list, the boolean in the output list is True if that integer was divisible by 7, or False if not. Use list comprehensions in python, the function only could be at most two lines long. Here is some examples: >>> div7([14, 5, 7, 3, 29, 28, 10]) [True, False, True, False,...

Write a PYTHON function CommonLetters(mystring) that takes mystring as input and returns the number of letters in mystring that also occur in the string ‘Python’. Using above function, write a program that repeatedly prompts the user for a string and then prints the number of letters in the string that are also in string ‘Python’. The program terminates when the user types an empty string.

All functions are written in python Write a function cube_evens_lc(values) that takes as input a list of numbers called values, and that uses a list comprehension to create and return a list containing the cubes of the even numbers in values (i.e., the even numbers raised to the third power). For example: >>> cube_evens_lc([2, 5, 6, 4, 1]) result: [8, 216, 64] This version of the function may not use recursion. Write a function cube_evens_rec(values) that takes as input a...

(Python) a) Using the the code below write a function that takes the list xs as input, divides it into nss = ns/nrs chunks (where nrs is an integer input parameter), computes the mean and standard deviation s (square root of the variance) of the numbers in each chunk and saves them in two lists of length nss and return these upon finishing. Hint: list slicing capabilities can be useful in implementing this function. from random import random as rnd...

Python: Write a function that receives a one dimensional array of integers and returns a Python tuple with two values - minimum and maximum values in the input array. You may assume that the input array will contain only integers and will have at least one element. You do not need to check for those conditions. Restrictions: No built-in Python data structures are allowed (lists, dictionaries etc). OK to use a Python tuple to store and return the result. Below...
