Error "open is not defined" inside a python automated action

Question

I like to create a small automated action with this code:

attachment = env['ir.attachment'].search_read([['res_id', '=', record.id]])
pdf = attachment[0].get("datas")
file = open("/odoo/sample.pdf", "wb")
file.write(pdf)
file.close()

but i get the error "open is not defined". Why could i not use the build-in open() function?

Only the following libraries are available in Automated Actions:
datetime
time
timezone
dateutil
math
*open* is a built-in Python function, but not one that can be used in the automation framework.
To use it you need to build your own module and use it inside a public model method that you can then call with the automation framework.
