# Sequence from Python expression

This module allows to generate a sequence by a Python formula expression.

Besides common Python functions and operators, it provides several functions like ‘random’ and ‘uuid’ in the expression, as well as variables such as the next number in the sequence. These are also listed next to the input field on the sequence form view.

If you want to add more variables for use in the expression, you can extend this module.

Use cases for this module could be:

- You want to generate alphanumeric numbering
- You want to apply some math to the number to prevent customers from knowing their place in the sequence
- You want to use UUID

# Usage

To use this module, you need to:

- Go to the form view of an ir.sequence record
- Go to the Python tab
- Enable the ‘Use Python’ checkbox
- Change the default ‘number’ expression to something more fancy.

Examples:

    # To separate the Odoo-generated number with hyphens eg. 0-0-0-0-1
    '-'.join(number_padded)

    # To have an UUID as the sequence value
    uuid.uuid4().hex

    # To use an 8-digit binary number
    '{0:#010b}'.format(number + 300)[2:]

And so on.
