python - 在 python 中向 csv 数据添加新行

Question

我正在尝试从 http://www.hoopsstats.com/basketball/fantasy/nba/opponentstats/16/12/eff/1-1 抓取数据使用 Python 3.5 创建 CSV 文件。我已经弄清楚了如何执行此操作，但是当我在 Excel 中打开文件时，所有数据都位于同一行中。

    import sys
import requests
from bs4 import BeautifulSoup
import csv

r = requests.get('http://www.hoopsstats.com/basketball/fantasy/nba/opponentstats/16/12/eff/1-1')


soup = BeautifulSoup(r.text, "html.parser")

stats = soup.find_all('table', 'statscontent')

pgFile = open ('C:\\Users\\James\\Documents\\testpoop.csv', 'w')

for table in soup.find_all('table', 'statscontent','a'):
    stats = [ stat.text for stat in table.find_all('center') ]
    team = [team for team in table.find('a')]


    p = (team,stats)

    z = str(p)



    a = z.replace("]",'') 
    b = a.replace("'", "")
    c = b.replace(")", "")   #Only way I knew how to clean up extra characters
    d = c.replace("(", "")
    e = d.replace("[", "")

    print(e)                 #printing while testing

    pgFile.writelines(e)
pgFile.close()

数据在 python shell 中显示得很好:

但是当在 Excel 中打开时，每个值都在它自己的单元格中，但它们都在第一行中。我想要为每个团队添加一个新行。

Answer 1

使用csv.writer将 CSV 数据写入 CSV 文件:

import csv

import requests
from bs4 import BeautifulSoup

r = requests.get('http://www.hoopsstats.com/basketball/fantasy/nba/opponentstats/16/12/eff/1-1')
soup = BeautifulSoup(r.text, "html.parser")

with open("output.csv", "w") as f:
    writer = csv.writer(f)

    for table in soup.find_all('table', class_='statscontent'):
        team = table.find('a').text
        stats = [team] + [stat.text for stat in table.find_all('center')]

        writer.writerow(stats)

现在，在 output.csv 中将写入以下内容:
