In XML,

Eg:-

<record id="id" model="ir.ui.view">
        <field name="name">xxxx</field>
        <field name="model">xxxx.xx</field>
        <field name="arch" type="xml">
            <form string="string" version="7.0">
                <group col="4">
                    <field name="aaa"/>
                    <field name="bbb" on_change="onchange_bbb(bbb)"/>
                    <field name="ccc"/>
                    <field name="ddd"/>
                </group>
            </form>
        </field>
    </record>

We pass the value bbb to the py file.

In Python:

Eg:-

def onchange_email(self, cr, uid, ids, bbb, context=None):
        vals = {'aaa': bbb}        
        return {'value': vals}

So the value of bbb is returned onchage to the field aaa.

Below example shows one onchange function for age calculation from date of birth(dob)

The xml view will be

<field name="dob" on_change="onchange_getage_id(dob,context)"/>

<field name="age_text"/>

while the date field is filled the age will be seen in the another text field.

The python onchange function is

 def onchange_getage_id(self,cr,uid,ids,dob,context=None):
        current_date=datetime.now()
        current_year=current_date.year
        birth_date = parser.parse(dob)
        current_age=current_year-birth_date.year
        val = {
            'age_text':current_age
        }
        return {'value': val}

Like this you can do your function.
