identify checksum type?

[PK]

Given a checksum value, whats the best way to find out what type it is?

meaning. I can use hashlib module and compute a md5 or sha1 for a given data
etc..but given a checksum value say "d2bda52ee39249acc55a75a0f3566105" whats
the best way for me to identify if its a sha1 or md5 or anyother sum type
for that matter?

is there a nice way to do this in python?
