python - 从 for 循环附加列表

问题描述

我正在尝试使用从网页收集的链接填充列表。该列表出现了意想不到的结果。我使用的代码有什么问题？

def get_contact_id(self):
    wd = self.app.wd
    elements = wd.find_elements_by_xpath("//a[contains(@href, 'edit.php?id')]")
    print(elements)
    links = []
    for i in elements:
        link = i.get_attribute('href')
        links.append(link)
        print(links)

我希望得到：

links = ['//192.168.1.22:8080/addressbook/edit.php?id=9','//192.168.1.22:8080/addressbook/edit.php?id=11','//192.168.1.22:8080/addressbook/edit.php?id=13','//192.168.1.22:8080/addressbook/edit.php?id=10','//192.168.1.22:8080/addressbook/edit.php?id=14']

相反，我得到：

links = ['//192.168.1.22:8080/addressbook/edit.php?id=9']
['//192.168.1.22:8080/addressbook/edit.php?id=9','//192.168.1.22:8080/addressbook/edit.php?id=10']
['//192.168.1.22:8080/addressbook/edit.php?id=9', '//192.168.1.22:8080/addressbook/edit.php?id=10', '//192.168.1.22:8080/addressbook/edit.php?id=11']
['//192.168.1.22:8080/addressbook/edit.php?id=9', '//192.168.1.22:8080/addressbook/edit.php?id=10', '//192.168.1.22:8080/addressbook/edit.php?id=11', '//192.168.1.22:8080/addressbook/edit.php?id=13']
['//192.168.1.22:8080/addressbook/edit.php?id=9', '//192.168.1.22:8080/addressbook/edit.php?id=10', '//192.168.1.22:8080/addressbook/edit.php?id=11', '//192.168.1.22:8080/addressbook/edit.php?id=13', '//192.168.1.22:8080/addressbook/edit.php?id=14']

解决方案

您需要links在 for 循环之外打印。

def get_contact_id(self):
    wd = self.app.wd
    elements = wd.find_elements_by_xpath("//a[contains(@href, 'edit.php?id')]")
    print(elements)
    links = []
    for i in elements:
        link = i.get_attribute('href')
        links.append(link)
    print(links)
