Is there any module or function in python I can use to convert a decimal number to its binary equivalent? I am able to convert binary to decimal using int('[binary_value]',2), so any way to do the reverse without writing the code to do it myself?

Without the 0b in front:
"{0:b}".format(int_value)
Starting with Python 3.6 you can also use formatted string literal or f-string, --- PEP:
f"{int_value:b}"
For the sake of completion: if you want to convert fixed point representation to its binary equivalent you can perform the following operations:
Get the integer and fractional part.
from decimal import * a = Decimal(3.625) a_split = (int(a//1),a%1)Convert the fractional part in its binary representation. To achieve this multiply successively by 2.
fr = a_split[1] str(int(fr*2)) + str(int(2*(fr*2)%1)) + ...
