python - 尝试使用 selenium Python 循环搜索查询时在 find_element_by_partial_link_text() 中出错

Question

我想做的是在 .csv 中为搜索查询和解析数据创建一个循环。但是，代码在此行 driver.find_element_by_partial_link_text(query).click() 上给出错误，Selenium 停止工作。无法弄清楚发生了什么。

from selenium import webdriver
from bs4 import BeautifulSoup 
import html5lib
import lxml.html
import csv 
import time

driver = webdriver.Chrome()
driver.get("url"


with open('your_csv.csv','r') as csvfile:
    with open('log.csv','wb') as csv_out:
        writer=csv.writer(csv_out)
        spamreader = csv.reader(csvfile)
        for query in spamreader:            
            username = driver.find_element_by_name("p_name")
            username.send_keys(query)
            driver.find_element_by_xpath("html/body/form/table[6]/tbody/tr/td[2]/input").click() #this will take you on new link
            time.sleep(4)
            driver.find_element_by_partial_link_text(query).click()

            html = driver.page_source
            soup = BeautifulSoup(html, 'html.parser')
            words = soup.find_all("td")
            ralph =  soup.get_text().encode('utf-8')

            a = list()
            for jav in words:
                    a.append((jav.text).encode('utf-8'))

            with open('data.csv', 'w') as csvfile:
                spamwriter = csv.writer(csvfile,delimiter=',')
                spamwriter.writerow(a)

这里是错误:

我发现 csv.reader() 返回每一行，作为字符串列表。带方括号。例如，如果 CSV 文件中的一行包含。 “贾维斯”。它将返回完全不符合语法的 ["jarvis"] 。这是我所做的。只是去掉方括号...

with open('your_csv.csv','r') as csvfile:
    with open('log.csv','wb') as csv_out:
        writer=csv.writer(csv_out)
        spamreader = csv.reader(csvfile)
        for query in spamreader:            
            username = driver.find_element_by_name("p_name")
            username.send_keys(str(query).strip('[').strip(']')
