Converting the received data into binary form in python

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:UsersUsereclipse-workspaceTrytest1test2.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.

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

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 errorValueError: invalid literal for int() with base 10: 'e'

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