# Convert List of 1s and 0s to a List of booleans in Python

This tutorial will discuss about unique ways to convert list of 1s and 0s to a list of booleans in Python.

## Introduction

Suppose we have a list of integers containing only 1s and 0s. Like this,

```listOfNums = [1, 0, 1, 1, 0, 0, 0, 1]
```

Now we want to convert this list of 1s and 0s to a List of booleans. Like this,

```[True, False, True, True, False, False, False, True]
```
• The 0 should be converted to False.
• The 1 should be converted to True.

Let’s how to do this.

## Method 1: Using List Comprehension

Iterate over elements of list, inside a List Comprehension, and call the `bool()` method on each element or number in the list. The `bool()` method will convert number `0` to `False`, and any other number to `True`. The List comprehension, will returned a new list containing these converted boolean values.

Let’s see the complete example,

```listOfNums = [1, 0, 1, 1, 0, 0, 0, 1]

# convert list of integers to list of bools
listOfBools = [bool(elem) for elem in listOfNums]

print(listOfBools)
```

Output

```[True, False, True, True, False, False, False, True]
```

## Method 2: Using NumPy Array

Create a `NumPy Array` from list of numbers, but pass the `dtype` as `bool` while constructing the NumPy Array. The array will have bools only i.e.

• The `0` will be converted to `False`.
• Anyother number will be converted to `True`.

Then convert this NumPy array to a list of booleans.

Let’s see the complete example,

```import numpy as np

listOfNums = [1, 0, 1, 1, 0, 0, 0, 1]

# create a NumPy Array of bool type from list
arr = np.array(listOfNums, dtype=bool)

# Convert numpy rray of bools to a Boolean list
listOfBools = arr.tolist()

print(listOfBools)
```

Output

```[True, False, True, True, False, False, False, True]
```

## Summary

We learned about two different ways to convert a list of 1s and 0s to list of bools in Python.
