Odoo hide edit and more buttons if not admin - python-2.7

Question

I'm trying to hide the edit and more button in user form if the connected user is not the admin.
Here is my code
<xpath expr='//form[#string="Users"]' position='attributes'>
<attribute name="edit" >{'false':[('id', '!=', '1')]}</attribute>
<attribute name="more">{'false':[('id', '!=', '1')]}</attribute>
</xpath>
i get the following error:
SyntaxError: JSON.parse: expected property name or '}' at line 1 column 2 of the JSON data

Answer 1

Unfortunately, what you trying achive is not possible using expression, rather I would advise to user "Customized Views"
Make out of user form edit="false" this will make edit button go away for all users (res.users.form).
Now go to Customized Views under Settings/Technical/User Interface/Customized Views, you need to be in debug mode to be able to see this menu.
Under Customized Views create a new record and choose User : Admin and in original view choose : res.users.form and in View Architecture
copy and pare original view View Architecture and just remove edit='false'
This should help, I believe.

Expanding #shodowsjedi's answer, To achieve what you want you have to create two views (They're essentially the same just that one is attached to a specific group and will be displayed for a user that belongs to that group)
This is a mockup of how your xml file should look
<!--original form view-->
<record id="model_form_view" model="ir.ui.view">
<field name="name">your.model</field>
<field name="model">your.model</field>
<field name="arch" type="xml">
<form string="Users">
<!--whatever is in your form -->
</field>
</record>
<!--inherited formview to hide edit option -->
<record id="model_form_view_noedit" model="ir.ui.view">
<field name="name">your.model</field>
<field name="model">your.model</field>
<field name="inherit_id" ref="model_form_view"/>
<field name="groups_id" eval="[(6, 0, [ref('base.group_user') ])]"/>
<field name="arch" type="xml">
<xpath expr='//form[#string="Users"]' position='attributes'>
<attribute name="edit">false</attribute>
</xpath>
</field>
</record>
It's always better to know how things work from the backend in Odoo
