# Convert a String to Binary in Python

When a string is converted to binary, it generates a list of binary values representing the original characters. Each character must be iterated over and converted to binary.

This article will discuss some methods to convert a string to its binary representation in Python.

## Convert a String to Its Binary Representation in Python Using the `format()` Function

We use the `ord()` function that translates the Unicode point of the string to a corresponding integer. The `format()` function converts an integer to a number in base two using the `b` binary format.

The complete example code is given below.

``````string = "Python"
binary_converted = ' '.join(format(ord(c), 'b') for c in string)
print("The Binary Representation is:", binary_converted)
``````

Output:

``````The Binary Represntation is: 1010000 1111001 1110100 1101000 1101111 1101110
``````

## Convert a String to Its Binary Representation in Python Using the `bytearray` Method

A byte array is a set of bytes that may store a list of binary data. Instead of iterating over the string explicitly, we can iterate over a byte sequence. It can be achieved without using the `ord()` function, but using the `bytearray()` function.

The complete example code is given below.

``````string = "Python"
binary_converted = ' '.join(format(c, 'b') for c in bytearray(string, "utf-8"))
print("The Binary Represntation is:", binary_converted)
``````

Output:

``````The Binary Representation is: 1010000 1111001 1110100 1101000 1101111 1101110
``````

## Convert a String to Its Binary Representation in Python Using the `map()` Function

We can also use the `map()` function in replacement of the `format()` function. `map()` convert string to a byte array using the `bytearray()` function and then use `bin` to convert the array of bytes in binary representation.

The complete example code is given below.

``````string = "Python"
binary_converted = ' '.join(map(bin, bytearray(string, "utf-8")))
print("The Binary Represntation is:", binary_converted)
``````

In Python 3, we must define an encoding scheme like `utf-8`; otherwise, an error will be raised.

Output:

``````The Binary Represntation is: 0b1010000 0b1111001 0b1110100 0b1101000 0b1101111 0b1101110
``````

## Convert a String to Its Binary Representation in Python Using the `ASCII` Method

In Python 3, `utf-8` is the default encoding scheme. But this method will use an `ASCII` encoding scheme instead of `utf-8`. For basic alphanumeric strings, the variations between `UTF-8` and `ASCII` encoding are not noticeable. But they will become significant if we are processing text that incorporates characters that are not part of the `ASCII` character collection.

The complete example code is given below:

``````st = "Python"
a_bytes = bytes(st, "ascii")
binary_converted=(' '.join(["{0:b}".format(x) for x in a_bytes]))
print("The Binary Represntation is:", binary_converted)
``````

Output:

``````The Binary Representation is: 1010000 1111001 1110100 1101000 1101111 1101110
``````
