In the previous article, we have discussed Python Program to Find Sum of Series 1/2!+2/3!+3/5!+…..N/(N+1)!

Given a number N and the task is to find the sum of series** (1^1/1+2^2/2+3^3/3…+N^N/N)** till the given number N in Python.

**Examples:**

**Example1:**

**Input:**

Given Number (Limit) = 4

**Output:**

The above series sum till the given number N{ 4 } = 76.0

**Example2:**

**Input:**

Given Number (Limit) = 9

**Output:**

The above series sum till the given number N{ 9 } = 45269999.0

## Program to Find Sum of Series 1^1/1+2^2/2+3^3/3…+n^n/n in Python

Below are the ways to find the sum of series** (1^1/1+2^2/2+3^3/3…+N^N/N)** till the given number N in Python:

### Method #1: Using For Loop (Static Input)

**Approach:**

- Import math module using the import keyword.
- Give the number N (Limit) as static input and store it in a variable.
- Take a variable to say
**rsltseries_summ**and initialize its value to 0.0 (Floating point number). - Loop from 1 to the given number using the for loop.
- Inside the loop, calculate the value of the iterator raised to the power itself and divided by the iterator value using the pow() function.
- Store it in another variable.
- Add the above result to the
**rsltseries_summ**and store it in the same variable. - Print the sum of series till the given number N.
- The Exit of the Program.

**Below is the implementation:**

# Import math module using the import keyword. import math # Give the number N(limit) as static input and store it in a variable. gvn_numb = 4 # Take a variable to say rsltseries_summ and initialize its value to 0.0 # (Floating point number) rsltseries_summ = 0.0 # Loop from 1 to the given number using the for loop. for itr in range(1, gvn_numb+1): # Inside the loop, calculate the value of the iterator raised to the power itself and # divided by the iterator value using the pow() function. # Store it in another variable. a = pow(itr, itr) / itr # Add the above result to the rsltseries_summ and store it in the same variable. rsltseries_summ += a # Print the sum of series till the given number N. print( "The above series sum till the given number N{", gvn_numb, "} = ", rsltseries_summ)

**Output:**

The above series sum till the given number N{ 4 } = 76.0

### Method #2: Using For loop (User Input)

**Approach:**

- Import math module using the import keyword.
- Give the number N (Limit) as user input using the int(input()) function and store it in a variable.
- Take a variable to say
**rsltseries_summ**and initialize its value to 0.0 (Floating point number). - Loop from 1 to the given number using the for loop.
- Inside the loop, calculate the value of the iterator raised to the power itself and divided by the iterator value using the pow() function.
- Store it in another variable.
- Add the above result to the
**rsltseries_summ**and store it in the same variable. - Print the sum of series till the given number N.
- The Exit of the Program.

**Below is the implementation:**

# Import math module using the import keyword. import math # Give the number N (Limit) as user input using the int(input()) function and # store it in a variable. gvn_numb = int(input("Enter some Random Number = ")) # Take a variable to say rsltseries_summ and initialize its value to 0.0 # (Floating point number) rsltseries_summ = 0.0 # Loop from 1 to the given number using the for loop. for itr in range(1, gvn_numb+1): # Inside the loop, calculate the value of the iterator raised to the power itself and # divided by the iterator value using the pow() function. # Store it in another variable. a = pow(itr, itr) / itr # Add the above result to the rsltseries_summ and store it in the same variable. rsltseries_summ += a # Print the sum of series till the given number N. print( "The above series sum till the given number N{", gvn_numb, "} = ", rsltseries_summ)

**Output:**

Enter some Random Number = 9 The above series sum till the given number N{ 9 } = 45269999.0
