What you are actually saying is that you have a value in a hexadecimal representation, and you want to represent an equivalent value in binary. The value of equivalence is an integer. But you may begin with a string, and to view in binary, you must end with a string. First, before we can do any binary manipulation at all, convert to int I presume this is in a string format, not as a literal:.
This uses the formatting specification's mini-language. If you actually just wanted to encode the data as a string of bytes in memory or on disk, you can use the int.
This is a slight touch up to Glen Maynard's solution, which I think is the right way to do it. It just adds the padding element. Pulled it out of a class. Just take out self, if you're working in a stand-alone script. The number 50 will tell zfill that you want to complete the string with zeros until the string length is I added the calculation for the number of bits to fill to Onedinkenedi's solution.
For solving the left-side trailing zero problem: Onedinkenedi 6 2. Doesn't provide leading zeros if hex string starts with This returns "binary" as in the actual bytes, but it does not convert it to a printable representation as "0" and "1". Doesn't that mean it returns a string? Yes, it returns a string containing the bytes represented, e. Any idea how to return ""? Oh, this also omits any leading '0's so it may need padded for this use. If the input is "1a" this gives "", not "" which may or may not be what you want.
There are an infinite number of leading zeroes on every number, so I'd hope it omits them. It's unfortunate that it's a global builtin. It should have been int. It's quite reasonable to need the leading zeros and to not need them. You might want the null byte 0x00 to be eight zero bits for example - this is important for some applications. Also the OP has a leading zero in his example but I suspect that's just random in this case!
Simple 2 3. John La Rooy k 33 Markus 1, 1 10 The new f-strings in Python 3. Convert hex to binary, 42 digits and leading zeros? We have several direct ways to accomplish this goal, without hacks using slices. First, before we can do any binary manipulation at all, convert to int I presume this is in a string format, not as a literal: Use the builtin function, format Then pass to format: To break that down, here's the grammar form of it: They use the same mini-language formatting rules: And since 42 bits divided by 8 bits per byte equals 6 bytes: Here's a fairly raw way to do it using bit fiddling to generate the binary strings.
The key bit to understand is: John Montgomery 5, 1 24 I know this is old, but what exactly is the point of the "and 1"? It's for the old days of python before the ternary operator.
We only want a one or zero, so that "and 1" is there to ensure that. This script worked best for me to convert a crypto private key in hex to binary for testing purposes. Does anyone know how to split the binary string into 8 bit chunks and print it out?
