Looping through an Object's members and changing its values

[Apothem]

Say I have:

PHP Code:

obj.one = "Hello, World!"
obj.two = "Goodbye, World!"
obj.three = "Foo"
obj.four = "Bar" 


1. How do I loop through it and change "o" to "a"?
2. Make the changed value permanent (i.e. I changed it by reference)
In PHP you, it's basically this:

PHP Code:

$v = (object)array('one' => "foooo", 'two' => "bo");
for( $v => &$val ) {
$val = str_replace('o', $val);
}

You can use the object's internal dictionary (assuming "obj" is an instance of some object):

for o in obj.__dict__:
    obj.__dict__[o] = "some new value"

If you have a source, like another dictionary that contains the same keys as the object's properties:

sauce = {"one": "some", "two": "value", "three": "here" }
for k, v in sauce.items():
    # Do nothing if k is not a property of obj.
    if obj.__dict__.get(k):
        obj.__dict__[k] = v

More to address your problem:

for key, value in obj.__dict__.items():
    obj.__dict__[k] = value.replace("o", "replacement text")
