Note: There is a space after each letter.
Explanation

For example, if the given number of rows is 4,
your code should print the following pattern.
A 
A B 
A B C 
A B C D

Sample Input 1
4
Sample Output 1
A 
A B 
A B C 
A B C D 

Sample Input 2

A B C D E 
A B C D E F 

You are given the temperature T of an object in one of Celsius, Fahrenheit, and Kelvin scales.
Write a program to print T in all scales viz Celsius, Fahrenheit, and Kelvin.
Formula to convert from Fahrenheit F to Celsius C is C = (F - 32) * 5 / 9.
Formula to convert from Kelvin K to Celsius C is C = K - 273.
Here "C", "F", "K" represent that the temperature scale is in Celsius, Fahrenheit and Kelvin scales respectively.
The input contains the temperature (a number) and the unit of the temperature scale (C, F, K) without any space.
The output contains temperature in Celsius, Fahrenheit and Kelvin scales in each line in the format similar to input and the value of the temperature is rounded to 2 decimal places.
Input

The first line of the input contain a temperature Value in one of Celsius, Fahrenheit, and Kelvin scales.
Output

The first line of output should contain the Celsius value and the unit of the Celsius without any space.
The second line of output should contain the Fahrenheit value and the unit of the Fahrenheit without any space.
The third line of output should contain the Kelvin value and the unit of the Kelvin without any space.
Explanation

For example, if the given temperature Value is 25C then Celsius value is 25.0C, Fahrenheit value is 77.0F, and Kelvin value is 298.0K.
Sample Input 1
25C
Sample Output 1
25.0C
77.0F
298.0K

Sample Input 2
37.5F
Sample Output 2
3.06C
37.5F
276.06K

Part 1

Write a Python program that does the following.

Create a string that is a long series of words separated by spaces. The string is your own creative choice. It can be names, favorite foods, animals, anything. Just make it up yourself. Do not copy the string from another source.

Turn the string into a list of words using split.

Delete three words from the list, but delete each one using a different kind of Python operation.

Sort the list.

Add new words to the list (three or more) using three different kinds of Python operation.

Turn the list of words back into a single string using join.

Print the string.

Part 2

Provide your own examples of the following using Python lists. Create your own examples. Do not copy them from another source.

Nested lists

The “*” operator

List slices

The “+=” operator

A list filter

A list operation that is legal but does the "wrong" thing, not what the programmer expects

Provide the Python code and output for your program and all your examples.

Part 3

Describe your experience so far with peer assessment of Programming Assignments.

How do you feel about the aspect assessments and feedback you have received from your peers?

How do you think your peers feel about the aspect assessments and feedback you provided them?

Describe the difference between objects and values using the terms “equivalent” and “identical”. Illustrate the difference using your own examples with Python lists and the “is” operator.

Describe the relationship between objects, references, and aliasing. Again, create your own examples with Python lists.

Finally, create your own example of a function that modifies a list passed in as an argument. Describe what your function does in terms of arguments, parameters, objects, and references.

Create your own unique examples for this assignment. Do not copy them from the textbook or any other source.

Matrix Rotations :-

You are given a square matrix A of dimensions NxN. You need to apply the below given 3 operations on the matrix A.

Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate the matrix A by angle S in the clockwise direction. The angle of rotation(S) will always be in multiples of 90 degrees.

Update: It is represented as U X Y Z. In initial matrix A (as given in input), you need to update the element at row index X and column index Y with value Z.

After the update, all the previous rotation operations have to be applied to the updated initial matrix.

Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A. Input

The first line contains a single integer N.

Next N lines contain N space-separated integers Aij (i - index of the row, j - index of the column).

Next lines contain various operations on the array. Each operation on each line (Beginning either with R, U or Q).

-1 will represent the end of input.Output

For each Query operation print the element present at row index K and colum index L of the matrix in its current state.

The below code is successful code for the question, but only one case is running successfully. sample inputs and outputs are given below :

def ReadMatrix():

  matrix = []

  for i in range(int(input())):

    row = [int(j) for j in input().split()]

    matrix.append(row) 

  return matrix

def RotateMatrix(matrix, degrees):

  n = len(matrix[0])

  rotations = (degrees // 90) % 4

  for r in range(rotations):

    temp_matrix = []

    for i in range(n):

      column = [row[i] for row in matrix]

      column.reverse()

      temp_matrix.append(column)

    matrix = temp_matrix

  return matrix

matrix = ReadMatrix()

rotation = 0

while True:

  line = input().split()

  if line[0] == "-1":

    break;

  elif line[0] == "R":

    rotation += int(line[1])

    matrix = RotateMatrix(matrix, int(line[1]))

  elif line[0] == "U":

     matrix[int(line[1])][int(line[2])] = int(line[3])

     matrix = RotateMatrix(matrix, rotation)

  elif line[0] == "Q":

    print(matrix[int(line[1])][int(line[2])])

  else:

    print("Error: unexpected command '" + line[0] + "'")

    exit(1)

Matrix Rotations

After the update, all the previous rotation operations have to be applied to the updated initial matrix.

Querying: It is represented as Q K L. You need to print the value at row index K and column index L of the matrix A.

Input

The first line contains a single integer N.

Next N lines contain N space-separated integers Aij (i - index of the row, j - index of the column).

Next lines contain various operations on the array. Each operation on each line (Beginning either with R, U or Q).

-1 will represent the end of input.

Output

For each Query operation print the element present at row index K and colum index L of the matrix in its current state.

Initial Matrix

3 4

For R 90, clockwise rotation by 90 degrees, the matrix will become

3 1

4 2

For Q 0 0, print the element at row index 0 and column index 0 of A, which is 3.

For Q 0 1, print the element at row index 0 and column index 1 of A, which is 1.

Again for R 90, clockwise rotation by 90 degrees, the matrix will become

4 3

2 1

For Q 0 0, print the element at row index 0 and column index 0 of A, which is 4.

For U 0 0 6, update the value at row index 0 and column index 1 in the initial matrix to 6. So the updated matrix will be,

6 2

3 4

After updating, we need to rotate the matrix by sum of all rotation angles applied till now(i.e. R 90 and R 90 => 90 + 90 => 180 degrees in clockwise direction).

After rotation the matrix will now become

4 3

2 6

Next for Q 1 1, print the element at row index 1 and column index 1 of A, which is 6.
