I've been trying to convert this string:

str = "68656c6c6f20776f726421"

to recover a ASCII value:

str = "hello word!"

I need some help with this please.

EDIT

Sorry for not giving more information, I'm a newbie, unfortunately.

but reading several pages of this wonderful site I found the solution.

the problem was that I got the string of a file, and a \n was printed, changing the length of the string.

Solution here: Python: binascii.a2b_hex gives "Odd-length string"

have you tried

codecs.decode(str, "hex").decode('utf-8')

You may need to assign this to a variable or print the results to see the output depending on your use case.

If I was doing this solution it would be the following:

data = bytes.fromhex(b'68656c6c6f20776f726421'.decode("ascii"))
print('The hex value converted to ascii is the following:',data.decode('utf-8'))

What is bytes here? What do you do with string?
well, the bytes here are the hex numbers. Hexadecimal numbers are defined as 0-9 and A-F. My apologies don't need string I thought I would. Thanks for keeping me on my toes with the answer.
