Answer #1

1.

CODE

lis1 = [10, 21, 30, 14, 5]

is_even = lambda x: x % 2 == 0

# using filter

lis2 = list(filter(is_even, lis1))

print(lis2)

2.

CODE

def is_list(p):

return isinstance(p, list)

def deepReverse(mylist):

result = []

for e in mylist:

if isinstance(e, list):

result.append(deepReverse(e))

else:

result.append(e)

result.reverse()

return result

print(deepReverse([1,2,[3,4,5],6]))

Write a Python function to count the number of even numbers from a list of numbers. Write a Python function that takes a list and returns a new list with unique elements of the first list. Sample List : [1,2,3,3,3,3,4,5] Unique List : [1, 2, 3, 4, 5]

Python Mutable Sequences Implement a function reverse that takes a list as an argument and reverses the list. You should mutate the original list, without creating any new lists. Do NOT return anything. Do not use any built-in list functions such as reverse(). def reverse(lst):    """Reverses lst in place (i.e. doesn't create new lists).     >>> L = [1, 2, 3, 4]     >>> reverse(L)     >>> L     [4, 3, 2, 1]     """

Python, using recursion Given an list of ints, compute recursively the number of times that the value 11 appears in the list. We'll use the convention of considering only the part of the list that begins at the given index. In this way, a recursive call can pass index+1 to move down the array. The initial call will pass in index as 0. array11([1, 2, 11], 0) → 1 array11([11, 11], 0) → 2 array11([1, 2, 3, 4], 0) →...

Assignment 1. Console Application IN PYTHON For this assignment you are to create a class called Lab1. Inside the class you will create three methods that will modify a three-digit whole number: sumNums - This method takes as input a three digit int and returns the sum of the three numbers. For instance, 123 would return 6 because 3 + 2 + 1 is 6 reverseNums - This method takes as input a three digit whole number and returns the...

PYTHON------------ Task 1- Remove Number Complete the function remove_number such that given a list of integers and an integer n, the function removes every instance of n from the list. Remember that this function needs to modify the list, not return a new list. Task 2- Logged List The log2() function is one of an algorithm designer’s favourite functions.
