Regular string of hex values to binary string
Question: I am writing a file-data searching script and want to allow the user to search
for a string of hex values (via `argv`). I had to switch from PHP to Python
because the maximum value of integers are (too) limited on 32-bit
PHP/machines. In PHP I could just do:

    
    
    $SearchValue = pack('H*', $Input);
    

However, in Python there does not seem to be any equivalent for this format
character. What are some alternatives for this conversion in Python, if any?
The output needs to be a binary string (`b'...'`).

I am quite new to Python so please bare with me.


Answer: 
    3>> import binascii
    3>> binascii.unhexlify('deadbeef')
    b'\xde\xad\xbe\xef'
