[PyQt] to display cotent of database between two dates

[atlass218]

I modify the code like you say but does'nt work.

and for information the variables 'start_date' and 'end_date' are recovered respectively from functions

def join_start_date(self):
    try:
        start_day = int(self.lineEdit_start_day.text())
        start_month = int(self.lineEdit_start_month.text())
        start_year = int(self.lineEdit_start_year.text())
        start_date = dt.date(start_year, start_month, start_day)
         
    except ValueError:    
        print("error")
         
    else:
        self.lineEdit_start_date_writted.setText("{:%Y-%m-%d}".format(start_date))
        print("OK")

	
def join_end_date(self):
    try:
        end_day = int(self.lineEdit_end_day.text())
        end_month = int(self.lineEdit_end_month.text())
        end_year = int(self.lineEdit_end_year.text())
        end_date = dt.date(end_year, end_month, end_day)
         
    except ValueError:    
        print("error")
         
    else:
        self.lineEdit_end_date_writted.setText("{:%Y-%m-%d}".format(end_date))
        print("OK")
