The sample code is below:

REFUND_STATUS = (('S', 'SUCCESS'),('F', 'FAIL')
)
refund_status = models.CharField(max_length=3, choices=REFUND_STATUS)

I know in the model I can retrieve the SUCCESS with method get_refund_status_display() method. However, if I want to do it reversely like: I have 'SUCCESS' I want to find the abbreviated form 'S'. How can I do that in django or python?

Convert it to a dict.

refund_dict = {value: key for key, value in REFUND_STATUS}
actual_status = refund_dict[display_status]
