Converting the received data into binary form in python

Question

I want to convert the received hex data into binary form. I get ValueError. For example, I want the first value in the output to be printed as 0000.

    received_data = " ".join("{:02x}".format(byte) for byte in (data))
    print(received_data)
    P_data = "{0:b}".format(received_data[0:1])

Output:

    01 04 04

Error:

    Traceback (most recent call last):
    File "C:\Users\User\eclipse-workspace\Try\test1\test2.py", line 22, in 
   <module>
    P_data="{0:b}".format(received_data[0:1])
    ValueError: Unknown format code 'b' for object of type 'str'

Why the intermediate hex representation? Going from from a stream of bytes to a stream of binary strings would be more straightforward. — NPE

You're probably looking for '{0:b}'.format(byte).zfill(8) ? You said binary form not hex? — Torxed

You should first convert your string into an integer

P_data = '{0:b}'.format(int(received_data[0:1], 16)).zfill(4)

If I receive hex in alphabets, it shows some error ValueError: invalid literal for int() with base 10: 'e'

Effectively, you should use base 16 instead (as it is hexadecimal), I edited my answer.
