## Binary Time :v:

As stated in the title **0s and 1s**, the provided text solely consists of 0s and 1s, which implies a binary string

{% hint style="info" %}
**Binary string** - Sequence of bytes (8 bits) where each byte represents a text character 
{% endhint %}

And the string is conveniently already split for us!

## Byte the Text

We can easily convert this string using online websites

{% embed url="<https://www.rapidtables.com/convert/number/binary-to-ascii.html>" %}

However, we could also code up a simple function in Python

```python
def binToText(binary):
    text = ""

    # Split the binary into bytes
    # Note this line may differ depending on the input
    binBytes = binary.split(' ')

    # Iterate over each byte
    for byte in binBytes:
        # Convert the base 2 byte into a base 10 number
        num = int(byte, 2)

        # Convert the number into its character counterpart
        char = chr(num)

        # Add to the string
        text += char
    
    return text
```
