What's the easiest way in python to concatenate string with binary values ?
sep = 0x1
data = ["abc","def","ghi","jkl"]
Looking for result data "abc0x1def0x1ghi0x1jkl"
with the 0x1 being binary value not string "0x1".
I think
joined = '\x01'.join(data)
should do it. \\x01
is the escape sequence for a byte with value 0x01.
The chr() function will have the effect of translating a variable into a string with the binary value you are looking for.
>>> sep = 0x1
>>> sepc = chr(sep)
>>> sepc
'\x01'
The join() function can then be used to concat a series of strings with your binary value as a separator.
>>> data = ['abc']*3
>>> data
['abc', 'abc', 'abc']
>>> sepc.join(data)
'abc\x01abc\x01abc'
I know this isn't the best method, but another way that could be useful in different context for the same question is:
>>> x=(str(bin(0b110011000)))
>>> b=(str(bin(0b11111111111)))
>>> print(x+b)
0b1100110000b11111111111
And if needed, to remove the left-most two bits of each string (ie 0b pad) the slice function [2:]
with a value of 2 works:
>>> x=(str(bin(0b110011000)[2:]))
>>> b=(str(bin(0b11111111111)[2:]))
>>> print(x+b)
11001100011111111111
