In this **python tutorial**, you will learn **how to Calculate Average Using Arrays** with the built in statements of the python programming language.

## How to Calculate Average Using Arrays?

Let’s take a look at the source code, here the values are assigned in the code, the built in statements carry out the function.

RUN CODE SNIPPET# Python program to get average of a list def Average(lst): return sum(lst) / len(lst) lst = [15, 19, 43, 31, 65, 24, 82, 59] average = Average(lst) print("Average of the list =", round(average, 2))

**OUTPUT:**

Average of the list = 42.25

- At the start, we use
`def Average(lst)`

where the`def`

keyword is used to define a function and the`Average(lst)`

is to call the average function to get the average of the values stored in the variable`(lst)`

- Using the
`return`

function and the built in functions`sum(lst)`

and`len(lst)`

, we return the sum of the values stored in the variable`(lst)`

divided by the length of the values stored in`(lst)`

- The formula for calculating the average of a list of values is the sum of all terms divided by the number of those terms as given above.
- We declare the variable
`(lst)`

equal to the values`[15, 19, 43, 31, 65, 24, 82, 59]`

, after which we declare the variable`average`

which is equal to the average of the variable`(lst)`

- Using the
`print`

function, we display the statement`("Average of the list =", round(average, 2))`

, where the`round`

function gives the rounded value of the obtained average value stored in the variable.

**NOTE:**

- The
**Sum() function**adds up all the numerical values in an iterable, such as a list, and returns the total of those values. - The
**Len() function**returns the length of an object. It is a built in function. - The
**Round()****function**returns a number that is a rounded version of the specified number, with the specified number of decimals. - The statement for the input function are enclosed in
**single quotes**and**parenthesis.** - The
**\n**in the code indicates a new line or the end of a statement line or a string. - The print statement/string to be displayed in enclosed in
**double quotes**.
