import datetime

def dateRange(beginDate, endDate):
    dates = []
    dt = datetime.datetime.strptime(beginDate, "%Y-%m-%d")
    date = beginDate[:]
    while date <= endDate:
        dates.append(date)
        dt = dt + datetime.timedelta(1)
        date = dt.strftime("%Y-%m-%d")
    return dates

if __name__ == '__main__':
    for date in dateRange('2018-02-01', '2018-02-10'):
        print date
