我是 python 新手，我正在尝试使用它来自动化工作中的手动表单填写任务。

我正在利用mechanicalsoup 功能来浏览网站并使用csv 文件中的值填写相同的表格。我可以确认下面的代码适用于我的 csv 中的第一行值，但在那之后会中断。我的 csv 文件有三列。

我真的很感激这方面的任何帮助。谢谢你。

这是我的代码：

#login
import mechanicalsoup
browser = mechanicalsoup.StatefulBrowser()
browser.open("<some website url>")
browser.select_form('form[action="/logins"]')
browser["username"] = "***"
browser["password"] = "*****"
browser.submit_selected()

#navigate to form and fill
def myfunction(esp, supnum, mid):
    url_esp = "<some website url>" + esp
    browser.open(url_esp)
    browser.follow_link("<some link>")
    url_facility = browser.get_url()
    url_facility_edit = url_facility + "<some link>"
    browser.open(url_facility_edit)
    browser.select_form('form[id="edit_facility"]')
    browser["facility[oracle_identifier]"] = supnum
    browser["facility[ffc_identifier]"] = mid
    response = browser.submit_selected()

#import values from csv to pass into function
import csv
with open('biweekly_oracle_esp_test.csv', 'r') as csv_file:
    reader = csv.reader(csv_file)
    for row in reader:
        esp = row[0]
        supnum = row[1]
        mid = row[2]
        myfunction(esp, supnum, mid)

这是错误：

Traceback (most recent call last):
  File "open_file_test2.py", line 32, in <module>
    myfunction(esp, supnum, mid)
  File "open_file_test2.py", line 19, in myfunction
    response = browser.submit_selected()
  File "C:\Python\lib\site-packages\mechanicalsoup\stateful_browser.py", line 232, in submit_selected
    *args, **kwargs)
  File "C:\Python\lib\site-packages\mechanicalsoup\browser.py", line 213, in submit
    response = self._request(form, url, **kwargs)
  File "C:\Python\lib\site-packages\mechanicalsoup\browser.py", line 155, in _request
    data.setdefault(name, []).append(value)
AttributeError: 'str' object has no attribute 'append'
