Given two numbers and the task is to find the addition of two numbers.

Also, given a list and the task is to find the addition of all the elements in a given list.

**Examples:**

**Example1:**

**Input:**

Given first number = 2 Given second number = 3

**Output:**

The addition of given two numbers { 2 + 3 } = 5

**Example2:**

**Input:**

Given List = [4, 7, 3, 1, 5]

**Output:**

The sum of all the elements of a given list [4, 7, 3, 1, 5] = 20

## Program to Perform Addition in Python

### Method #1: Using + Operator (Static Input)

**1) Addition using Functions**

**Approach:**

- Create a function say Additionof_2numbers() which accepts the given two numbers as the arguments and returns the addition of given two numbers.
- Inside the function, add the given two numbers and store it in a variable.
- Return the above result.
- Give the first number as static input and store it in a variable.
- Give the second number as static input and store it in another variable.
- Pass the given two numbers as the arguments to the Additionof_2numbers() function and store it in another variable.
- Print the addition of given two numbers
- The Exit of the program.

**Below is the implementation:**

# Create a function say Additionof_2numbers() which accepts the given two numbers # as the arguments and returns the addition of given two numbers. def Additionof_2numbers(gvn_num1, gvn_num2): # Inside the function, add the given two numbers and store it in a variable. rsltsum = gvn_num1 + gvn_num2 # Return the above result. return(rsltsum) # Give the first number as static input and store it in a variable. gvn_num1 = 2 # Give the second number as static input and store it in another variable. gvn_num2 = 3 # Pass the given two numbers as the arguments to the Additionof_2numbers() function # and store it in another variable. fnl_summ = Additionof_2numbers(gvn_num1, gvn_num2) # Print the addition of given two numbers print("The addition of given two numbers {",gvn_num1,"+",gvn_num2,"} = ",fnl_summ)

**Output:**

The addition of given two numbers { 2 + 3 } = 5

**2)Addition of list Elements using for loop**

**Approach:**

- Give the list as static input and store it in a variable.
- Take a variable and initialize its value to 0.
- Loop in the given list using the for loop.
- Add the element of the given list to the above declared rslt_sum variable and store it in the same variable.
- Print the sum of all the elements of a given list.
- The Exit of the program.

**Below is the implementation:**

# Give the list as static input and store it in a variable. gvn_lst = [4, 7, 3, 1, 5] # Take a variable and initialize its value to 0. rslt_sum = 0 # Loop in the given list using the for loop. for elemnt in gvn_lst: # Add the element of the given list to the above declared rslt_sum variable # and store it in the same variable. rslt_sum = rslt_sum+elemnt # Print the sum of all the elements of a given list. print("The sum of all the elements of a given list", gvn_lst, "= ") print(rslt_sum)

**Output:**

The sum of all the elements of a given list [4, 7, 3, 1, 5] = 20

### Method #2: Using + Operator (User Input)

**Approach:**

- Create a function say Additionof_2numbers() which accepts the given two numbers as the arguments and returns the addition of the given two numbers.
- Inside the function, add the given two numbers and store it in a variable.
- Return the above result.
- Give the first number as user input using the int(input()) function and store it in a variable.
- Give the second number as user input using the int(input()) function and store it in another variable.
- Pass the given two numbers as the arguments to the Additionof_2numbers() function and store it in another variable.
- Print the addition of two numbers.
- The Exit of the program.

**Below is the implementation:**

# Create a function say Additionof_2numbers() which accepts the given two numbers # as the arguments and returns the addition of given two numbers. def Additionof_2numbers(gvn_num1, gvn_num2): # Inside the function, add the given two numbers and store it in a variable. rsltsum = gvn_num1 + gvn_num2 # Return the above result. return(rsltsum) # Give the first number as user input using the int(input()) fucntion and store it in a variable. gvn_num1 = int(input("Enter some random number = ")) # Give the second number as user input using the int(input()) fucntion and store it in another variable. gvn_num2 = int(input("Enter some random number = ")) # Pass the given two numbers as the arguments to the Additionof_2numbers() function # and store it in another variable. fnl_summ = Additionof_2numbers(gvn_num1, gvn_num2) # Print the addition of given two numbers print("The addition of given two numbers {",gvn_num1,"+",gvn_num2,"} = ",fnl_summ)

**Output:**

Enter some random number = 55 Enter some random number = 45 The addition of given two numbers { 55 + 45 } = 100

**2)Addition of list Elements using for loop**

**Approach:**

- Give the list as user input using list(),map(),input(),and split() functions.
- Store it in a variable.
- Take a variable and initialize its value to 0.
- Loop in the given list using the for loop.
- Add the element of the given list to the above declared rslt_sum variable and store it in the same variable.
- Print the sum of all the elements of a given list.
- The Exit of the program.

**Below is the implementation:**

# Give the list as user input using list(),map(),input(),and split() functions. # Store it in a variable. gvn_lst = list(map(int, input( 'Enter some random List Elements separated by spaces = ').split())) # Take a variable and initialize its value to 0. rslt_sum = 0 # Loop in the given list using the for loop. for elemnt in gvn_lst: # Add the element of the given list to the above declared rslt_sum variable # and store it in the same variable. rslt_sum = rslt_sum+elemnt # Print the sum of all the elements of a given list. print("The sum of all the elements of a given list", gvn_lst, "= ") print(rslt_sum)

**Output:**

Enter some random List Elements separated by spaces = 6 7 3 1 2 The sum of all the elements of a given list [6, 7, 3, 1, 2] = 19
