如何获取选定年份的所有日期表单？

def get_dates_of_year(year):
    # 判断是否为闰年
    if year % 4 == 0 and (year % 100 != 0 or year % 400 == 0):
        days_in_month = [31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
    else:
        days_in_month = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
    
    dates = []
    
    # 遍历每个月份
    for month in range(1, 13):
        # 遍历每一天
        for day in range(1, days_in_month[month-1] + 1):
            date = f"{year}-{month:02d}-{day:02d}"  # 格式化日期字符串
            dates.append(date)
    
    return dates

# 示例用法
year = 2022
dates = get_dates_of_year(year)
print(dates)
