How to ORDER BY DESCENDING the years in a selection

Question

I used this code for the data in the selection

def _get_years(self):
this_year = datetime.today().year

results = [(str(x), str(x)) for x in range(this_year - 40, this_year + 1)]
return results

year_selection = fields.Selection(_get_years, string="Select Year", default=current_year)

Just write following code and call this method into selection field like :
def _get_years(self):
this_year = datetime.today().year
results = sorted([(str(x), str(x)) for x in range(this_year - 40, this_year + 1)],reverse = True)
return results
year_selection : fields.Selection(_get_years,string="select year)

Hi Dee Yoj,

Try This Code
from datetime import datetime
from odoo import fields , models , api

class  YourClass (models.Model):
_inherit = 'your.model'
this_year = datetime.today().year
range_of_years = range(this_year - 40 , this_year + 1 )
descending_range = sorted(range_of_years ,  reverse = True )
_get_years = [(str(x) , str(x)) for x in descending_range]
year_selection = fields.Selection(_get_years ,  string = "Select Year" )
Thank you.
