# Convert base-2 binary number string to int

To convert a binary string to an integer, Python's `int()`

function paired with `2`

as the base easily does the job:

This enjoyable little one-liner effectively turns binary code, the language of computers, into human-readable numbers. But why stop here? Let's dive deeper.

## Elementary conversion methods

### The Python way: str-prefix

Python has its own binary literal representation — the prefix `'0b'`

. With this, you can tell Python directly that a string is a binary number:

### The champ: bitstring

When you need to do more than just convert, the `bitstring`

module is your knight in shining armor with its additional features:

### The big player: numpy

Got a large heap of binary numbers? Fear not, `numpy`

is there to make your conversion efficient and fast:

### The artisan way: zip and bitwise

Want to convert binary strings the hard way because why not? You have `zip`

and bitwise operations:

## Bitwise operations and potential errors

While performing conversions, you may need to use bitwise operations and cater to potential errors:

### The bitwise playbook

Bitwise operations are the James Bond gadgets of binary manipulation:

### An unexpected guest - ValueError

Binary strings can sometimes carry invalid data (`'2021'`

). In such scenarios, Python raises a `ValueError`

:

## Performance considerations

Lastly, ensure smooth performance. While Python's `int()`

function is your trusty steed for binary-to-integer conversions, `numpy`

is your warhorse when dealing with large binary datasets.
