以下代码有效,但是在2月29日之后停止。网站返回“您输入的日期无效。请重新输入搜索结果”,这需要单击“确定”。我该如何解决?
country_search("United States")
time.sleep(2)
date_select = Select(driver.find_element_by_name("dr"))
date_select.select_by_visible_text("Enter date range...") #All Dates
select_economic_news()
#btnModifySearch
for month in range(1,9):
for day in range(1,32):
try:
set_from_month(month)
set_from_date(day)
set_from_year("2020")
set_to_month(month)
set_to_date(day)
set_to_year("2020")
time.sleep(5)
#select_economic_news()
time.sleep(5)
search_now()
time.sleep(8)
export_csv()
modify_search()
time.sleep(5)

如果您只能使用初始文章中介绍的方法,那么我会尝试以下方法:
set_from_year('2020')
set_to_year('2020')
for month in range(1, 9):
# 1 to 9 for Jan to Aug
month_str = '0' + str(month)
set_from_month(month_str)
set_to_month(month_str)
for day in range(1, 32):
# Assuming an error is thrown for invalid days
try:
# Store data as needed
except Exception as e:
# print(e) to learn from error if needed
pass
如果事实证明您自己编写这些方法,并且需要遍历HTML并找到每日数据的模式,那么还有很多其他事情。

我相信您希望动态获取一个月中的天数,以便可以循环使用该天数以获取每个日期的数据。您可以按照以下步骤进行操作:
from datetime import datetime
currentDay = datetime.today()
# You can set the currentDay using this if you want the data till the current date or
# whenever your scheduler runs the job.
# Now you need to get the number of days in each month from the chosen date, you can
# have the corresponding function like getStartMonth() in your program which will
# return the starting month.
from calendar import monthrange
daysPerMonth = {}
year = currentDay.year #TODO : change this to getStartYear()
startMonth = 3 # TODO : Implement getStartMonth() in your code.
for month in range(startMonth, currentDay.month+1):
# monthrange returns (weekday,number of days in that month)
daysPerMonth[month] = monthrange(year, month)[1]
for month in daysPerMonth.items():
print(month[0], '-',month[1])
这将输出如下内容(从2020年3月到2020年8月的一个月中的天数):
3 - 31
4 - 30
5 - 31
6 - 30
7 - 31
8 - 31
然后您可以运行一个天数循环,同时从您获得的字典中引用范围。 注意:在运行循环以获取每个日期数据的函数中,添加一个if条件以检查它是否是一年中的最后一天,并相应地修改年份。

也许您可以使用以下功能来获取每月的天数:
import datetime
def get_month_days_count(year: int, month: int) -> int:
date = datetime.datetime(year, month, 1)
while (date + datetime.timedelta(days=1)).month == month:
date = date + datetime.timedelta(days=1)
return date.day
