Decode Hex String in Python 3

Question

In Python 2  converting the hexadecimal form of a string into the corresponding unicode was straightforward   comments decode  hex     where the variable  comments  is a part of a line in a file  the rest of the line does not need to be converted  as it is represented only in ASCII   Now in Python 3  however  this doesn t work  I assume because of the bytes string vs  string unicode switch  I feel like there should be a one-liner in Python 3 to do the same thing  rather than reading the entire line as a series of bytes  which I don t want to do  and then converting each part of the line separately  If it s possible  I d like to read the entire line as a unicode string  because the rest of the line is in unicode  and only convert this one part from a hexadecimal representation

Something like    gt  gt  gt  bytes fromhex  4a4b4c   decode  utf-8    JKL    Just put the actual encoding you are using

The answers from  unbeli and  Niklas are good  but  unbeli s answer does not work for all hex strings and it is desirable to do the decoding without importing an extra library  codecs   The following should work  but will not be very efficient for large strings     gt  gt  gt  result   bytes fromhex  lambda s     s s00     len s   2     tuple s    4a82fdfeff00    decode  utf-16-le    gt  gt  gt  result      x4a x82 xfd xfe xff x00  True   Basically  it works around having invalid utf-8 bytes by padding with zeros and decoding as utf-16
