Program to Find the Sum of Series 1+X+X^3…+X^N in Python

Below are the ways to find the sum of the given series (1+X+X^3…+X^N) for the given numbers in Python :

Method #1: Using While Loop (Static Input)

Approach:

  • Give the number N as static input and store it in a variable.
  • Give the value of X as static input and store it in another variable.
  • Take a variable say resltsum which gives the sum of the given series till N and initialize its value to 0.
  • Take another variable say k and initialize its value with 1.
  • Loop until the value of k is less than or equal to the given number using the while loop.
  • Inside the loop, calculate the value of X raised to the power k using the pow() function and store it in a variable say p.
  • Add the above value of p to the resltsum and store it in the same variable.
  • Increment the value of k by 2 and store it in the same variable k.
  • Print the resltsum value which is the result of the series till the given Number N.
  • The Exit of the Program.

Below is the implementation:

# Give the number N as static input and store it in a variable.
gvn_numb = 4
# Give the value of x as static input and store it in another variable.
gvn_x_val = 8
# Take a variable say resltsum which gives the sum of the given series till N and
# initialize its value to 0.
resltsum = 0
# Take another variable say k and initialize its value with 1.
k = 1
# Loop until the value of k is less than or equal to the given number using the while loop.
while(k <= gvn_numb):
    # Inside the loop, calculate the value of X raised to the power k using the pow() function
    # and store it in a variable say p.
    p = pow(gvn_x_val, k)
 # Add the above value of p to the resltsum and store it in the same variable.
    resltsum += p
 # Increment the value of k by 2 and store it in the same variable k.
    k += 2
# Print the resltsum value which is the result of the series till the given Number N.
print(
    "The total sum of the series till the given number N and x value {", gvn_numb, gvn_x_val, "} = ", resltsum)

Output:

The total sum of the series till the given number N and x value { 4 8 } =  520

Method #2: Using While loop (User Input)

Approach:

  • Give the number N as user input using the int(input()) function and store it in a variable.
  • Give the value of X as user input using the int(input()) function and store it in another variable.
  • Take a variable say resltsum which gives the sum of the given series till N and initialize its value to 0.
  • Take another variable say k and initialize its value with 1.
  • Loop until the value of k is less than or equal to the given number using the while loop.
  • Inside the loop, calculate the value of X raised to the power k using the pow() function and store it in a variable say p.
  • Add the above value of p to the resltsum and store it in the same variable.
  • Increment the value of k by 2 and store it in the same variable k.
  • Print the resltsum value which is the result of the series till the given Number N.
  • The Exit of the Program.

Below is the implementation:

# Give the number N as user input using the int(input()) function and
# store it in a variable.
gvn_numb = int(input("Enter some Random Number = "))
# Give the value of X as user input using the int(input()) function and
# store it in another variable.
gvn_x_val = int(input("Enter some Random Number = "))
# Take a variable say resltsum which gives the sum of the given series till N and
# initialize its value to 0.
resltsum = 0
# Take another variable say k and initialize its value with 1.
k = 1
# Loop until the value of k is less than or equal to the given number using the while loop.
while(k <= gvn_numb):
    # Inside the loop, calculate the value of X raised to the power k using the pow() function
    # and store it in a variable say p.
    p = pow(gvn_x_val, k)
 # Add the above value of p to the resltsum and store it in the same variable.
    resltsum += p
 # Increment the value of k by 2 and store it in the same variable k.
    k += 2
# Print the resltsum value which is the result of the series till the given Number N.
print(
    "The total sum of the series till the given number N and x value {", gvn_numb, gvn_x_val, "} = ", resltsum)

Output:

Enter some Random Number = 5
Enter some Random Number = 11
The total sum of the series till the given number N and x value { 5 11 } = 162393

Python Program to Read and Display a Matrix

Python / By

In the previous article, we have discussed Python Program to find the Sum of Series 1^1+2^2+3^3…+N^N
Given a matrix, the task is to scan and print the elements of the given matrix in Python

What is a matrix:

A matrix is a rectangular sequence of numbers divided into columns and rows. A matrix element or entry is a number that appears in a matrix.

Example:

Above is the matrix which contains 5 rows and 4 columns and having elements from 1 to 20.

In this order, the dimensions of a matrix indicate the number of rows and columns.

Here as there are 5 rows and 4 columns it is called a 5*4 matrix.

Program to Read and Display a Matrix in Python

Below are the ways to read and display the elements of the given matrix in Python:

Method #1: Using list Method

Approach:

  • Give the number of rows of the matrix as user input using the int(input()) function and store it in a variable.
  • Give the number of columns of the matrix as user input using the int(input()) function and store it in another variable.
  • Take a list and initialize it with an empty value using [] or list() to say gvnmatrix.
  • Loop till the given number of rows using the For loop
  • Inside the For loop, Give all the row elements of the given Matrix as a list using the list(),map(),int(),split() functions and store it in a variable.
  • Add the above row elements list to gvnmatrix using the append() function.
  • To print all the elements of the given matrix.
  • Loop till the given number of rows using the For loop.

  • Print the element of the matrix by printing gvnmatrix[n][m] value where n is the iterator value of the parent For loop and m is the iterator value of the inner For loop.
  • The Exit of the Program.

Below is the Implementation:

# Give the number of rows of the matrix as user input using the int(input()) function
# and store it in a variable.
mtrxrows = int(input('Enter some random number of rows of the matrix = '))
# Give the number of columns of the matrix as user input using the int(input()) function
# and store it in another variable.
mtrxcols = int(input('Enter some random number of columns of the matrix = '))
# Take a list and initialize it with an empty value using [] or list() to say gvnmatrix.
mtrx = []
# Loop till the given number of rows using the For loop
for n in range(mtrxrows):
    # Inside the For loop, Give all the row elements of the given Matrix as a list using
    # the list(),map(),int(),split() functions and store it in a variable.
    l = list(map(int, input(
        'Enter {'+str(mtrxcols)+'} elements of row {'+str(n+1)+'} separated by spaces = ').split()))
    # Add the above row elements list to gvnmatrix using the append() function.

    mtrx.append(l)

# To print all the elements of the given matrix.
# Loop till the given number of rows using the For loop.
for n in range(mtrxrows):

  • Inside the loop, check if the iterator value of the hexadecimal string is greater than or equal to 0 and less than or equal to 9 using the if conditional statement.
  • If it is true, then convert the iterator value of the hexadecimal string into an integer using the int() function.
  • Assign its value to the above-initialized rslt_val.

  • Inside the loop, check if the iterator value of the hexadecimal string is greater than 0 and less than 9 using the if conditional statement.
  • If it is true, then convert the iterator value of the hexadecimal string into an integer using the int() function.
  • Assign its value to the above-initialized rslt_val.
  • Check if the iterator value of the hexadecimal string is equal to ‘A’ or ‘a’ using the if conditional statement.
  • If it is true, then assign value 10 to the above-initialized rslt_val.
  • Check if the iterator value of the hexadecimal string is equal to ‘B’ or ‘b’ using the if conditional statement.
  • If it is true, then assign value 11 to the above-initialized rslt_val.
  • Check if the iterator value of the hexadecimal string is equal to ‘C’ or ‘c’ using the if conditional statement.
