Python string to attribute

Solution 1:

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.

Solution 2:

If someobject has an attribute named foostring then

def get_foo(someobject, foostring):
    return getattr(someobject,foostring)

or if you want to set an attribute to the supplied object then:

def set_foo(someobject, foostring, value):
    return setattr(someobject,foostring, value)

Try it

Solution 3:

You should use setattr and getattr:

setattr(object,'property',value)
getattr(object,'property',default)
