# Convert List of Tuples to List of Lists in Python (3 Examples)

Hi! This tutorial will show you 3 examples of how to transform a list of tuples to a list of lists in the Python programming language.

First, though, here is a quick overview of this tutorial:

Let’s get right into the Python code!

## Create Sample List of Tuples

Here, we will create the sample list of tuples that will be turned into a list of lists in this tutorial. So, in your preferred Python programming IDE, run the line of code below to create the sample list of tuples containing integer pairs.

`tuple_list = [(1, 2), (3, 4), (5, 6)]`

## Example 1: Transform List of Tuples to List of Lists with map() Function

In this first example, we will use Python’s map() function to turn the list of tuples to a list of lists.

```list_list = list(map(list, tuple_list))
print(list_list)

# [[1, 2], [3, 4], [5, 6]]

print(type(list_list))

# <class 'list'>```

In the above code, we used the `map()` function to iteratively apply the `list()` constructor to the tuples in the original list of tuples tuple_list, and a list of lists is returned as the output.

## Example 2: Transform List of Tuples to List of Lists with For Loop

In this next example, we will use a for loop to transform the list of tuples to a list of lists.

```list_list = []
for t in tuple_list:
list_list.append(list(t))
print(list_list)

# [[1, 2], [3, 4], [5, 6]]

print(type(list_list))

# <class 'list'>```

In the above example, we used a for loop to iterate over the tuples in the original list of tuples tuple_list and converted each tuple to a list using the `list()` constructor, and appended the resulting list to a new list list_list.

## Example 3: Transform List of Tuples to List of Lists with List Comprehension

In this third and final example, we will use list comprehension to convert the list of tuples to a list of lists.

```list_list = [list(t) for t in tuple_list]
print(list_list)

# [[1, 2], [3, 4], [5, 6]]

print(type(list_list))

# <class 'list'>```

In the code above, we used a list comprehension to iterate through the tuples in the original list, then converted each tuple into a list, using the `list()` constructor, and then appended the resulting lists to a new list. It works exactly like the for loop in the previous example; just more concise.

With that, we have demonstrated 3 simple ways to turn a list of tuples into a list of lists in Python. I hope you found this tutorial helpful!
