You don't encrypt the string, you hash it. Therefore, it can't be "decrypted" - hashes are meant to be one way functions, i.e. there is no simple way to "calculate" the input from the output.
See e.g. here for more detailed definitions of encrypting and hashing: Difference between Hashing a Password and Encrypting it

Oh !! thanks...is there any way of encrypting and decrypting a string
codeling
hm searching for that ("python encryption" or similar) on the search engine of your choice should give plenty results... what about this: stackoverflow.com/a/16761459/671366 or this: eli.thegreenplace.net/2010/06/25/… ?
You are creating a hash of the input string. You can use this hash to check if another input string is the same as the original input string.
You are not supposed to be able to decrypt a hash. That would defeat the whole purpose.
