如何使Python循环以不同的行写入CSV？

我是Python新手，我有一个脚本，可以根据我想要的代码获取雅虎金融公司的名称、行业和行业信息，所有内容都会在不同的单元格中写入CSV，但只在一行中。如何使每个excel行按我输入的股票代码显示公司名称、行业和行业

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait
import csv

def get_all():
    results = []
    for x in tickers:
        try:
            website = "http://finance.yahoo.com/quote/{0}/profile?p={0}".format(x)
            driver = webdriver.Chrome()
            driver.get(website)
            wait = WebDriverWait(driver, 10)
            company = wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="main-0-Quote-Proxy"]/section/div[2]/section/div/div[1]/div/h3')))
            results.append(company.text)
            wait = WebDriverWait(driver, 10)
            sector = wait.until(EC.visibility_of_element_located((By.XPATH, "//span[. = 'Sector']/following-sibling::strong")))
            results.append(sector.text)
            wait = WebDriverWait(driver, 10)
            industry = wait.until(EC.visibility_of_element_located((By.XPATH, "//span[. = 'Industry']/following-sibling::strong")))
            results.append(industry.text)
            driver.close()
        except Exception as e: 
            error_msg = "Error on {0}-{1}".format(x,e) 
            results.append(error_msg)
            driver.close()
    print(results)
    out = csv.writer(open("yahoo_companies.csv","w"), delimiter=',',quoting=csv.QUOTE_ALL)
    out.writerow(results)

# Enter tickers below
tickers = ['COST', 'BBY']
get_all()

例如，我希望它给我（每个分号都是不同的单元格）：

第1行：好市多批发公司；服务；打折，杂货店

第二行：百思买股份有限公司。；服务；电子商店

第三行：等等

---

现在我得到（全部在第一排）：好市多批发公司；服务；折扣店、杂货店；百思买股份有限公司。；服务；Electronics商店

在每行末尾，您应该有一个换行符（\n\r），以便CSV编辑程序理解

如果将每一行添加到自己的列表中并将其附加到主“结果”列表中，writerows将为每个元素添加行终止

请参阅下面的代码

def get_all():
    results = []
    for x in tickers:
        # declare a new list to hold the values in each row
        newRow = []
        try:
            website = "http://finance.yahoo.com/quote/{0}/profile?p={0}".format(x)
            driver = webdriver.Chrome()
            driver.get(website)
            wait = WebDriverWait(driver, 10)
            company = wait.until(EC.visibility_of_element_located((By.XPATH, '//*[@id="main-0-Quote-Proxy"]/section/div[2]/section/div/div[1]/div/h3')))
            # appending to newRow list
            newRow.append(company.text)
            wait = WebDriverWait(driver, 10)
            sector = wait.until(EC.visibility_of_element_located((By.XPATH, "//span[. = 'Sector']/following-sibling::strong")))
            # appending to newRow list
            newRow.append(sector.text)
            wait = WebDriverWait(driver, 10)
            industry = wait.until(EC.visibility_of_element_located((By.XPATH, "//span[. = 'Industry']/following-sibling::strong")))
            # appending to newRow list
            newRow.append(industry.text)
            driver.close()
        except Exception as e: 
            error_msg = "Error on {0}-{1}".format(x,e) 
            # appending to newRow list
            newRow.append(error_msg)
            driver.close()
        # append the newRow list into 'results list'
        results.append(newRow)
    print(results)
    outFile = open("yahoo_companies.csv","w")
    out = csv.writer(outFile, delimiter=',',quoting=csv.QUOTE_ALL)
    # see the following line, its writerows (plural). different to your code.
    out.writerows(results)
    outFile.close()

检查缩进和

result

声明。问一个小问题，为什么要使用请求来代替selenium？顺便说一句，如果你使用API会更好谢谢你的提示！另外，我正在学习我听说要快得多的请求。@wu4m4n:您发布的链接以字典形式显示了所有公司信息。如何在新脚本中获取此信息？
