Python string to attribute

Question

Hello, How can I achieve such job:

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

IE:

if I do get_foo(obj, "name") it should be calling obj.name (see input as string but I call it as an attritube.

Thanks

Answer 1

You should use setattr and getattr:

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

Answer 2

Use the builtin function getattr

getattr(...)
    getattr(object, name[, default]) -> value

    Get a named attribute from an object; getattr(x, 'y') is equivalent to x.y.
    When a default argument is given, it is returned when the attribute doesn't
    exist; without it, an exception is raised in that case.

Answer 3

if someobject has attribute foostring then

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

or if u want to set attribute to supplied object then:

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

Try it

Thanks
