In Python, working with lists is a common task. Sometimes, we need to find the largest number in a list. This can be useful in a variety of applications, from data analysis to simple programming tasks. In this tutorial, we will explore different methods to find the biggest number in a list in Python. By the end of this tutorial, you will have a solid understanding of how to find the maximum value in a list and be able to apply this knowledge to your own Python projects.

## Methods to find the biggest number in a list in Python

There are multiple methods using which you can get the maximum value in a Python list. Let’s look at these methods in detail with the help of some examples.

### 1) Using the `max()`

function

`max()`

is a built-in function in Python that returns the largest item in an iterable or the largest of two or more arguments. To get the biggest number in a list, pass the list as an argument to the `max()`

function.

Let’s look at an example.

# create a list ls = [3, 5, 1, 9, 2] # find the biggest value in the list biggest_num = max(ls) print(biggest_num)

Output:

9

We get the maximum value in the list as 9, which is the correct answer.

### 2) By iterating through the list

In this method, we iterate through the list and keep track of the biggest value encountered in a separate variable. After we have gone through the entire list, the variable will have the biggest value in the list.

# create a list ls = [3, 5, 1, 9, 2] # find the biggest value in the list if ls: biggest_num = ls[0] for val in ls[1:]: if val > biggest_num: biggest_num = val print(biggest_num) else: print("list is empty")

9

You can see that we get 9 as the biggest value in the list, which is the correct answer.

### 3) Sort the list

The idea here is to sort the list in ascending order and get the last element in the list. In a sorted list, the largest number will be at the end of the list. You can use the built-in `sorted()`

function to sort a list in Python, it returns a new list that is sorted.

# create a list ls = [3, 5, 1, 9, 2] # sort the list ls_sorted = sorted(ls) # find the biggest value print(ls_sorted[-1])

Output:

9

We get the biggest value in the last as 9, which is the correct answer.

## Conclusion

In this tutorial, we looked at how to get the biggest number in a Python list using different methods. Using the `max()`

is the simplest and the recommended way to get the largest value in a list. The other methods, while being correct, are not as straightforward as the `max()`

function.
