finding the start date end day in python

S = dt.datetime(2022, 3, 2).date()
E = dt.date(2023, 7, 31)
startyear = S.year
startmonth = S.month
while (startyear, startmonth) <= (E.year, E.month):
    print(dt.date(startyear, startmonth, 1))
    if startmonth == 12:
        startyear = startyear + 1
        startmonth = 1
    else:
        startmonth = startmonth + 1
