how to convert data in a log file to ASCII string by Python?

I got some log files from a search engine. The following is supposed to be country names but I failed to converted it to ASCII in Python. Any help will be appreciated. 

Data: 505a44facaa3e758845f6e101f4e21f9d99acf63

Code: 

ascii_string = str(base64.b16decode(hex_data))[2:-1]

Error: Non-base16 digit found

If you want to decode the hex from the Data string:

s = "Data: 505a44facaa3e758845f6e101f4e21f9d99acf63"
print( s.split()[1].decode("hex")

For python3 use unhexlify:

print(binascii.unhexlify(s.split()[1]))

But neither will return a country name.

Your string is actually "GB" sha1 hashed.

In [9]: import sha

In [10]: sha.new("GB").hexdigest()
Out[10]: '505a44facaa3e758845f6e101f4e21f9d99acf63'

Are you sure that 505a44facaa3e758845f6e101f4e21f9d99acf63 represents an encoded country? It looks suspiciously like the hex digest of a SHA1 hash.

hex_data implies that the data is hex encoded. It can be decoded like this:

>>> hex_data = '505a44facaa3e758845f6e101f4e21f9d99acf63'
>>> hex_data.decode('hex')
'PZD\xfa\xca\xa3\xe7X\x84_n\x10\x1fN!\xf9\xd9\x9a\xcfc'

Where to go from there is anyone's guess.

I think that you just need to convert hex_data to upper case:

ascii_string = str(base64.b16decode(hex_data.upper()))[2:-1]
