program to count Even and Odd numbers in a List Using Python Lambda Expressions

list1 = [10, 21, 4, 45, 66, 93, 11]

odd_count = len(list(filter(lambda x: (x%2 != 0) , list1)))

even_count = len(list(filter(lambda x: (x%2 == 0) , list1)))

print("Even numbers in the list: ", even_count)

print("Odd numbers in the list: ", odd_count)

Break a list into chunks of size N

my_list = ['python', 'for', 'engineers', 'like',

'complete','solution', 'for', 'python',

'related','queries']

def divide_chunks(l, n):

for i in range(0, len(l), n):

yield l[i:i + n]

n = 5

x = list(divide_chunks(my_list, n))

print (x)

Matrix creation of n*n Using next() + itertools.count()

import itertools

N = 4

print("The dimension : " + str(N))

temp = itertools.count(1)

res = [[next(temp) for i in range(N)] for i in range(N)]

print("The created matrix of N * N: " + str(res))

Program for Find remainder of array multiplication divided by n

from functools import reduce

def find_remainder(arr,n):

   sum_1=reduce(lambda x,y: x*y,arr)

   remainder=sum_1%n

   print(remainder)

arr=[100,10,5,25,35,14]

n=11

find_remainder(arr,n)

Reconstruct the array by replacing arr[i] with (arr[i-1]+1) % M

def construct(n, m, a):

ind = 0

for i in range(n):

if (a[i]!=-1):

ind = i

break

for i in range(ind-1, -1, -1):

if (a[i]==-1):

a[i]=(a[i + 1]-1 + m)% m

for i in range(ind + 1, n):

if(a[i]==-1):

a[i]=(a[i-1]+1)% m

print(*a)

n, m = 6, 7

a =[5, -1, -1, 1, 2, 3]

construct(n, m, a)
