Python String to Attribute

Python string to attribute

Use the builtin function getattr.

getattr(object, name[, default])

Return the value of the named attribute of object. name must be a string. If the string is the name of one of the object’s attributes, the result is the value of that attribute. For example, getattr(x, 'foobar') is equivalent to x.foobar. If the named attribute does not exist, default is returned if provided, otherwise AttributeError is raised.

The operator.attrgetter function does this:

import operator
print operator.attrgetter("bar.baz.quux")(f)     # prints "Found me!"
