How to concatenate strings with binary values in python?

Question

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".

Answer 1

I think

joined = '\x01'.join(data) 

should do it. \x01 is the escape sequence for a byte with value 0x01.
