# How to Find the Sum of Elements in List in Python | Python Program

In this article, we will learn to find the sum of the elements in a List using the python program.

We find the sum of the elements in the list using 3 methods:

1. Using loop
2. Using Recursion
3. Using sum() function

## Using loop

### Explanation

Using iteration of the list, we add the elements one by one in a variable and lastly print the sum of the elements.

### Program

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14``` ```# List List = [1, 2, 3, 4, 5, 6] # init the sum variable sum = 0 # iterate the list for ele in List: # update the sum with elements of the list # add all the elements in sum variable sum += ele # prin the sum of the elements print("The sum of the elements is:",sum) ```

### Output

```The sum of the elements is: 21
```

## Using Recursion

### Explanation

Using recursion we find the sum of the elements of the list. Ada last elements and update the size value to -1 and add one by one.

### Program

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19``` ```# List list = [1, 2, 3, 4, 5, 6] # size of the list size = len(list) # make a function sum_of_elements def sum_of_elements(list, size): if size == 0: return 0 else: # add all the elements by recursion return list[size-1] + sum_of_elements(list, size-1) sum = sum_of_elements(list, size) # prin the sum of the elements print("The sum of the elements is:",sum) ```

### Output

```The sum of the elements is: 21
```

## Using sum() function

### Explanation

The sum() function is used to find the sum of all elements.

### Program

 ```1 2 3 4 5 6 7 8``` ```# List list = [1, 2, 3, 4, 5, 6] # use sum() functon to add all the elements total = sum(list) # prin the sum of the elements print("The sum of the elements is:",total) ```

### Output

```The sum of the elements is: 21
```
