in python 3.7.2 i am trying to test bitcoin testnet code. 
i am trying to convert odd length testnet private key to byte format but no matter what i try i cannot do it there is always some error mainly because all the functions i tried cannot Handel odd length address.
any suggestions guys? so far i have tried

```
import codecs 
odd_len_str = "93AZYqkwkPsKAjHg7FqjXVMukwRrXkzGXYFNUsov2zFhDdfH8DT" #length=51
decode_hex = codecs.getdecoder("hex_codec") 
decode_hex(odd_len_str)[0]

import binascii
binascii.hexlify(odd_len_str) #doesn't work

bytes.fromhex(odd_len_str) #doesn't work

```

error msg from the first method is:

```
_codec.py", line 19, in hex_decode
    return (binascii.a2b_hex(input), len(input))
binascii.Error: Odd-length string

```
