'str' object is not callable error while using 'Find an element' by link text or XPATH in Selenium Python

Question

我是编码新手，正在尝试通过 Python 学习 Selenium。我想点击下载按钮，但出现错误“'Str' object not callable”。使用 Python 3.10 和 Selenium 4.1.3

这是我的代码：

import os

from selenium import webdriver

from selenium.webdriver.common.by import By

os.environ['PATH'] += r"C:\SeleniumDrivers"

driver = webdriver.Chrome()

driver.get("https://www.python.org/downloads")

driver.implicitly_wait(10)

my_element = driver.find_element(By.XPATH("//a[contains(@href,'Download Python 3.10.4')]"))

my_element.click()

Answer 1

我假设您想单击“下载 Python”。如果是，那么这段代码就可以完成工作，

my_element = driver.find_element(by = By.XPATH, value = "//*[@id='touchnav-wrapper']/header/div/div[2]/div/div[3]/p/a")
my_element.click()

你的代码有两个问题-

你做到了 By.XPATH("//a[contains(@href,'Download Python 3.10.4')]")。这里By.XPATH其实不是一个函数，只是一个值为“XPATH”的变量，所以不能在里面传递参数。这就是为什么您会收到 'str' object is not callable 错误。对于 XPATH，您需要使用类似 driver.find_element(by = By.XPATH, value = <XPATH>).
的内容
即使您上面所做的是正确的，您传递的 XPATH 也是不正确的。正确的 XPATH 是 my_element = driver.find_element(by = By.XPATH, value = "//*[@id='touchnav-wrapper']/header/div/div[2]/div/div[3]/p/a").
