## Program to find the Sum of Series 1^1+2^2+3^3…+N^N in Python

Below are the ways to find the sum of the given series** 1^1+2^2+3^3+…..+N^N** for the given number in Python:

- Using For loop and pow() function (Static Input)
- Using For loop and pow() function (User Input)
- Using For loop and ** operator (Static Input)
- Using For loop and ** operator (User Input)

### Method #1: Using For loop and pow() function (Static Input)

**Approach:**

- Give the number N as static input and store it in a variable.
- Take a variable say
**resltsum**which gives the sum of the given series till N and initialize its value to 0. - Loop from 1 to given number using the For loop.
- Inside the For loop, Calculate the value of iterator value ^ iterator value using the pow function and store it in a variable.
- Add the above variable to the
**resltsum**. - 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. gvnNumbr = 3 # Take a variable say resltsum which gives the sum of # the given series till N and initialize its value to 0. resltsum = 0 # Loop from 1 to given number using the For loop. for k in range(1, gvnNumbr+1): # Inside the For loop, Calculate the value of iterator value ^ iterator value # using the pow function and store it in a variable. powervl = pow(k, k) # Add the above variable to the resltsum resltsum = resltsum+powervl # Print the resltsum value which is the result of the series till the given Number N. print( 'The sum of the series till the given number {', gvnNumbr, '} is :', resltsum)

**Output:**

The sum of the series till the given number { 3 } is : 32

### Method #2: Using For loop and pow() function (User Input)

**Approach:**

- Give the number N as user input using the int(input()) function and store it in a variable.
- Take a variable say
**resltsum**which gives the sum of the given series till N and initialize its value to 0. - Loop from 1 to given number using the For loop.
- Inside the For loop, Calculate the value of iterator value ^ iterator value using the pow function and store it in a variable.
- Add the above variable to the
**resltsum**. - 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. gvnNumbr = int(input('Enter some random number N = ')) # Take a variable say resltsum which gives the sum of # the given series till N and initialize its value to 0. resltsum = 0 # Loop from 1 to given number using the For loop. for k in range(1, gvnNumbr+1): # Inside the For loop, Calculate the value of iterator value ^ iterator value # using the pow function and store it in a variable. powervl = pow(k, k) # Add the above variable to the resltsum resltsum = resltsum+powervl # Print the resltsum value which is the result of the series till the given Number N. print( 'The sum of the series till the given number {', gvnNumbr, '} is :', resltsum)

**Output:**

Enter some random number N = 7 The sum of the series till the given number { 7 } is : 873612

### Method #3: Using For loop and ** operator (Static Input)

**Approach:**

- Give the number N as static input and store it in a variable.
- Take a variable say
**resltsum**which gives the sum of the given series till N and initialize its value to 0. - Loop from 1 to given number using the For loop.
- Inside the For loop, Calculate the value of iterator value ^ iterator value using the ** operator and store it in a variable.
- Add the above variable to the
**resltsum**. - 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. gvnNumbr = 5 # Take a variable say resltsum which gives the sum of # the given series till N and initialize its value to 0. resltsum = 0 # Loop from 1 to given number using the For loop. for k in range(1, gvnNumbr+1): # Inside the For loop, Calculate the value of iterator value ^ iterator value # using the ** operator # and store it in a variable. powervl = k**k # Add the above variable to the resltsum resltsum = resltsum+powervl # Print the resltsum value which is the result of the series till the given Number N. print( 'The sum of the series till the given number {', gvnNumbr, '} is :', resltsum)

**Output:**

The sum of the series till the given number { 5 } is : 3413

### Method #4: Using For loop and ** operator (User Input)

**Approach:**

- Give the number N as user input using the int(input()) function and store it in a variable.
- Take a variable say
**resltsum**which gives the sum of the given series till N and initialize its value to 0. - Loop from 1 to given number using the For loop.
- Inside the For loop, Calculate the value of iterator value ^ iterator value using the ** operator and store it in a variable.
- Add the above variable to the
**resltsum**. - 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. gvnNumbr = int(input('Enter some random number N = ')) # Take a variable say resltsum which gives the sum of # the given series till N and initialize its value to 0. resltsum = 0 # Loop from 1 to given number using the For loop. for k in range(1, gvnNumbr+1): # Inside the For loop, Calculate the value of iterator value ^ iterator value # using the ** operator # and store it in a variable. powervl = k**k # Add the above variable to the resltsum resltsum = resltsum+powervl # Print the resltsum value which is the result of the series till the given Number N. print( 'The sum of the series till the given number {', gvnNumbr, '} is :', resltsum)

**Output:**

Enter some random number N = 6 The sum of the series till the given number { 6 } is : 50069
