Secret Message - 1

Given a string, write a program to mirror the characters of the string in alphabetical order to create a secret message.

Note: Mirroring the characters in alphabetical order replacing the letters 'a' with 'z', 'b' with 'y', ... , 'z' with 'a'. You need to mirror both uppercase and lowercase characters. You can ignore mirroring for all characters that are not letters.

a b c d e f g h i j k l m n o p q r s t u v w x y z

z y x w v u t s r q p o n m l k j i h g f e d c b a

Explanation

Input

For example, if the given input is "python", "p" should replaced with "k", similarly "y" with "b", "t" with "g", "h" with "s", "o" with "l", "n" with "m". So the output should be "kbgslm".

Weekends

Given two dates D1 and D2, write a program to count the number of Saturdays and Sundays from D1 to D2 (including D1 and D2).

The date in string format is like "8 Feb 2021".Input

The first line of input will contain date D1 in the string format.

The second line of input will contain date D2 in the string format.

Output

The output should be a single line containing two integers separated by space

Explanation

For example, if the given dates are "25 Jan 2021" and "14 Feb 2021", the Saturdays and Sundays dates from "25 Jan 2021" to "14 Feb 2021" are

"30 Jan 2021" is a Saturday

"31 Jan 2021" is a Sunday

"6 Feb 2021" is a Saturday

"7 Feb 2021" is a Sunday

"13 Feb 2021" is a Saturday

"14 Feb 2021" is a Sunday

output

Saturday: 3

Sunday: 3

Sample Input 1

25 Jan 2021

14 Feb 2021

Sample Output 1

Saturday: 3

Sunday: 3

Sample Input 2

25 May 2019

22 Dec 2021

Sample Output 2

Saturday: 135

Sunday: 135

polinom = {}

for i in range(2):

n = int(input())

for item in range(n):

p, c = input().split(' ')

p, c = int(p), int(c)

if p in polinom:

polinom[p] += c

else:

polinom[p] = c

res = ''

if len(polinom) == 0:

pass

else:

flag = True

for p in polinom:

if polinom[p] == 0:

continue

if polinom[p] < 0:

if flag:

res += '-'

else:

res += ' - '

else:

if not flag:

res += ' + '

flag = False

if (abs(polinom[p]) == 1) and p == 0:

res += '1'

continue

if abs(polinom[p]) != 1:

res += str(abs(polinom[p]))

if p < 0:

res += 'x^({})'.format(p)

elif p == 1:

res += 'x'

elif p > 0:

res += 'x^{}'.format(p)

if len(res) == 0:

print('0')

else:

print(res)

Output:6 + 2x + 14x^2 + 6x^3
Expected output:6x^3 + 14x^2 + 2x + 6

n = int(input())

polinom_a =[0 for item in range(n)]                      

for item in range(n):

  p, c = input().split(' ')

  polinom_a[int(p)] = int(c)

m = int(input())

polinom_b =[0 for item in range(m)]

for item in range(m):

  p, c = input().split(' ')

  polinom_b[int(p)] = int(c)

pol_max , pol_min = polinom_a , polinom_b

if len(pol_min) > len(pol_max):

  pol_max , pol_min = polinom_b , polinom_a 

for item in range(len(pol_min)):

  pol_max[item] += pol_min[item]

for item in range(len(pol_max)-1,0,-1):

  if item == 0:

    continue

  print (f'{pol_max[item]}x^{item} + ',end='')

print(pol_max[0])

ouput:6x^3 + 14x^2 + 2x^1 + 6
the ouput should be like this:6x^3 + 14x^2 + 2x + 6 
after adding two polynomials when we get "0" as output and it should print output as:"0"

so,please can anyone make correct code?

All Possible Subsets

Given a sentence as input, print all the unique combinations of the words of the sentence, considering different possible number of words each time (from one word to N unique words in lexicographical order).Input

The input will be a single line containing a sentence.Output

The output should be multiple lines, each line containing the unique combination from one word to N words in lexicographical order.Explanation

For example, if the given sentence is "apple is a fruit".

All possible one-word unique combinations are

a
apple
fruit
is

All possible two words unique combinations are

a apple
a fruit
a is
apple fruit
apple is
fruit is

All possible three words unique combinations are

a apple fruit
a apple is
a fruit is
apple fruit is

All possible four words unique combinations are

You are designing a quiz game to help elementry school students with fraction calculations

Your games should have a set of 25 addition, subtraction, multiplication, division questions located in a file. Each question should be formatted to look like:

• 3/4+4/5
• 5/8*9/4

The questions should be displayed to the player 1 question at a time and reward the player points for gettting the answer to that question correct.

• Question was correct the first time (4 Points in Lowest Terms, 3 Points not in lowest terms)
• Question was incorrect the first time but correct on second guess (2 Points in Lowest Terms, 1 Point not in lowest terms)
• Question incorrect after second guess (0 Points)

Your program should always display the correct answer in lowest terms if the player didn't answer in lowest terms correctly

Your program should append the players name and score to a file when complete.

You must design and code a Fraction Object to complete this program

compute average numbers from 1 to n where n is a positiove integer value and assign it to the variable avg in python

inputString =input("");

sumDigits =0

numberDigits=0

# Looping through a string.

for character in inputString:

  if (character.isdigit()):

    # Calculate the sum of the digits of all numbers that appear in the string

    sumDigits+=int(character)

    numberDigits+=1

# Calculate the average of the digits of all numbers that appear in the string

average=sumDigits/numberDigits

# Print the sum of all digits(8) 

print(str(sumDigits))

# Print the average of all digits(2.0) in the new line.

print("%.1f" % average)

input:

for row in output:

print(*row)

input:

-50 20 3 25 -20

88 17 38 72 -10

output:-
50 -20 -10 3 17
-10 3 17 20 25
the output should be like this:-
50 -20 -10 3 17 
20 25 38 72 88

so can anyone please give correct code?

Given two polynomials A and B, write a program that adds the given two polynomials A and B.Input

If the add polynomials is euqal to zero it should print output:"0"
