Convert binary to string using Python - GeeksforGeeks
July 12, 2025 - This method breaks the binary string into chunks of 8 bits and converts each chunk into a character using int() and chr() functions. It’s a clean and readable way to convert binary to text and works well for small to medium-length strings.

How to convert an integer into a binary number without the specific function?
The idea is to repeatedly divide your number by 2, keeping track of the remainder each time, eg. def to_binary(n): assert n >= 0, 'Must be positive' binary = '' while n: # while n is not 0 n, r = divmod(n, 2) # the same as: n, r = n//2, n%2 binary = str(r) + binary # prepend the remainder to the output return binary or '0' # if the string is still empty, n must have been 0 More on reddit.com

Otherwise, the bytes object underlying the buffer object is obtained before calling bytes.decode(). See Binary Sequence Types — bytes, bytearray, memoryview and Buffer Protocol for information on buffer objects. Passing a bytes object to str() without the encoding or errors arguments falls under the first case of returning the informal string representation (see also the -b command-line option to Python).

December 27, 2021 - If we open up a file with the mode of rb, we're opening that file not in the default read-text mode, but instead in read-binary mode. >>> with open("avatar.jpg", mode="rb") as jpg_file: ... jpg_data = jpg_file.read() ... So when we read from that file, the data that we get out of it will not be a string, it'll be a bytes object. ... In fact in this case where we're opening up a jpg file, we get a bytes object with a lot of bytes in it, because it takes a lot of bytes to represent an image: ... If you end up with a bytes object in Python, and you know that the object represents text, you can turn it into a string by calling its decode method:

is there any proper method to convert a string in utf-8 encoded formant to binary string format and the reverse too. like example
data = "this string".encode("utf-8")
data = func(data)
print(data) #want to have a string as output like "0101010101111010101010......."

Something like this?
>>> st = "hello world"
>>> ' '.join(format(ord(x), 'b') for x in st)
'1101000 1100101 1101100 1101100 1101111 100000 1110111 1101111 1110010 1101100 1100100'
#using `bytearray`
>>> ' '.join(format(x, 'b') for x in bytearray(st, 'utf-8'))
'1101000 1100101 1101100 1101100 1101111 100000 1110111 1101111 1110010 1101100 1100100'

If by binary you mean bytes type, you can just use encode method of the string object that encodes your string as a bytes object using the passed encoding type. You just need to make sure you pass a proper encoding to encode function.
In [9]: "hello world".encode('ascii')
Out[9]: b'hello world'
In [10]: byte_obj = "hello world".encode('ascii')
In [11]: byte_obj
Out[11]: b'hello world'
In [12]: byte_obj[0]
Out[12]: 104
Otherwise, if you want them in form of zeros and ones --binary representation-- as a more pythonic way you can first convert your string to byte array then use bin function within map :
>>> st = "hello world"
>>> map(bin,bytearray(st))
['0b1101000', '0b1100101', '0b1101100', '0b1101100', '0b1101111', '0b100000', '0b1110111', '0b1101111', '0b1110010', '0b1101100', '0b1100100']
Or you can join it:
>>> ' '.join(map(bin,bytearray(st)))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'
Note that in python3 you need to specify an encoding for bytearray function :
>>> ' '.join(map(bin,bytearray(st,'utf8')))
'0b1101000 0b1100101 0b1101100 0b1101100 0b1101111 0b100000 0b1110111 0b1101111 0b1110010 0b1101100 0b1100100'
You can also use binascii module in python 2:
>>> import binascii
>>> bin(int(binascii.hexlify(st),16))
'0b110100001100101011011000110110001101111001000000111011101101111011100100110110001100100'
hexlify return the hexadecimal representation of the binary data then you can convert to int by specifying 16 as its base then convert it to binary with bin.

Python question: string of binary to an actual binary number | Ars OpenForum
January 7, 2014 - Oddly (considering Python's "include all the things!" mentality), there actually isn't a succinct inverse to int(x, base) which will take an int and output a string of an arbitrary base (so, if for some strange reason you're trying to do base 5 math in python, you'll have to do a bit more work to convert into a base 5 string).

Python 3.X Strings Tutorial by Mark Lutz
If you deal with binary data—for example, in the form of image or audio files, network transfers, or packed data processed with the struct module—you will need to understand 3.0's new bytes object and its different and sharper distinction between text and binary data and files. If you fall into neither of the prior two categories, you can generally use strings in 3.0 much as you would in 2.6: with the general str string type, text files, and all the familiar string operations.
