Substitute class method with a string in Python

Question

Lets say that I want to do this

hashlibAlgo = "md5"
Hash= hashlib.**"hashlibAlgo"**("blah blah blah").hexdigest()

How can I do that. If I substitute the name of a method with a string it obviously does not work. How can I make it work? In powershell is easy, but I cannot figure it in Python.

Answer 1

You can get function to execute with getattr:

>>> import hashlib
>>> hashlibAlgo = "md5"
>>> getattr(hashlib, hashlibAlgo)("blah blah blah").hexdigest()
'55e562bfee2bde4f9e71b8885eb5e303'
