获取间隔均匀的日期列表

from datetime import datetime, timedelta

def get_date_list(start_date, end_date, interval):
    date_list = []
    current_date = datetime.strptime(start_date, "%Y-%m-%d")
    end_date = datetime.strptime(end_date, "%Y-%m-%d")

    while current_date <= end_date:
        date_list.append(current_date.strftime("%Y-%m-%d"))
        if interval == "day":
            current_date += timedelta(days=1)
        elif interval == "week":
            current_date += timedelta(weeks=1)
        elif interval == "month":
            current_date = current_date.replace(day=1)
            current_date += timedelta(days=31)
        elif interval == "year":
            current_date = current_date.replace(month=1, day=1)
            current_date += timedelta(days=365)

    return date_list

# 示例用法
start_date = "2022-01-01"
end_date = "2022-12-31"
interval = "month"
date_list = get_date_list(start_date, end_date, interval)
print(date_list)
