How to resolve AssertionType error

fio_2 = fields.Integer('FIO₂(󠀥%)')
    a_gradient = fields.Integer('A-a gradient', states={
        'invisible': ~Eval('fio_2') >= 50 and ~Eval('fio_2') <= 100,
    }, depends=['fio_2'])
    a_gradient_point = fields.Function(
        fields.Integer('A-a gradient Points', states={

        }, depends=['a_gradient']),
        'on_change_with_a_gradient_point')

On executing above code error showing up below:
File “/home/khushboo/workspace/tryton/tryton50/src/trytond/trytond/pyson.py”, line 300, in init
‘statement must be an integer or a float’
AssertionError: statement must be an integer or a float

PYSON Eval uses the default value to determine the statement type. If no default value is set it uses an empty string. In your case the default value is a string (due to the empty string default value) which raises the AssertionError due to a comparision between char and integer.

You should specify a float default value for your code in order to resolve the ArrertionError. Something like:

fio_2 = fields.Integer('FIO₂(󠀥%)')
    a_gradient = fields.Integer('A-a gradient', states={
        'invisible': ~Eval('fio_2',0) >= 50 and ~Eval('fio_2',0) <= 100,
    }, depends=['fio_2'])
    a_gradient_point = fields.Function(
        fields.Integer('A-a gradient Points', states={
            'invisible': ~Eval('a_gradient'),
        }, depends=['a_gradient']),
        'on_change_with_a_gradient_point')

Note that I’ve converted Eval('fio_2') into Eval('fio_2', 0)

Hope it helps!

Sir, how will I specify a float default value for my code. Any guidance will be a great help.

Combine the word default and the field name into a function. Like:

fio_2 = fields.Integer('FIO₂(󠀥%)')
    a_gradient = fields.Integer('A-a gradient', states={
        'invisible': ~Eval('fio_2') >= 50 and ~Eval('fio_2') <= 100,
    }, depends=['fio_2'])


@staticmethod
def default_fio_2():
    return 40.0

I think on Pyson you should use ‘&’ instead ‘and’

I have coded the code like given below:

fio_2 = fields.Integer('FIO₂(󠀥%)')
    a_gradient = fields.Integer('A-a gradient', states={
        'invisible': ~Eval('fio_2', 0) >= 50 and ~Eval('fio_2', 0) <= 100,
    }, depends=['fio_2'])
    a_gradient_point = fields.Function(
        fields.Integer('A-a gradient Points', states={
            'invisible': ~Eval('a_gradient'),
        }, depends=['a_gradient']),
        'on_change_with_a_gradient_point')
@staticmethod
    def default_fio_2():
        return 0.0

But still the same error is coming:

Any further recommendation from your side will be helpful.

As @dabada83 said:

must use & instead of and like

'invisible': ~Eval('fio_2', 0) >= 50 & ~Eval('fio_2', 0) <= 100

Sir, i have written the code like this, as follows:

    a_gradient_point = fields.Function(
        fields.Integer('A-a gradient Points', states={

        }, depends=['a_gradient']),
        'on_change_with_a_gradient_point')

    @fields.depends('a_gradient')
    def on_change_with_a_gradient_point(self, name=None):

    pao2 = fields.Integer('PaO2', states={

    pao2_point = fields.Function(
        fields.Integer('PaO2 Points', states={
            'invisible': ~Eval('pao2'),
        }, depends=['pao2']),
        'on_change_with_pao2_point')

    @fields.depends('pao2')
    def on_change_with_pao2_point(self, name=None):

Indeed ~ is equivalent to “not” so it is a Boolean expression type which can not be compared to integers.
So I guess you want:

'invisible': (Eval('fio_2', 0) < 50) & (Eval('fio_2', 0) > 100)

Check the parenthesis because they are required as & operator has binary operator has precedence over comparison operators.
