在python中将信息写入csv

我正在尝试将信息写入csv，这样每个信息都有自己的单元格。我玩的代码越多，要么出现缩进错误，要么第一行打印到csv，就是这样

缩进错误：预期缩进块

我认为首先要考虑的是打开文件并在循环外创建CSV写入器。我认为您在每次通过

for

循环时都会覆盖CSV文件（

'w'

）。所以试试这个：

import requests
from bs4 import BeautifulSoup
import csv
from urlparse import urljoin
import urllib2

base_url = 'http://www.baseball-reference.com/' # base url for concatenation
data = requests.get("http://www.baseball-reference.com/teams/BAL/2014-schedule-scores.shtml") #website for scraping
soup = BeautifulSoup(data.content)
b=5

for link in soup.find_all('a'):

    if not link.has_attr('href'):
        continue

    if link.get_text() != 'boxscore':
        continue

    url = base_url + link['href']

    response = requests.get(url)
    html = response.content
    soup = BeautifulSoup(html)

    # Scores
    table = soup.find('table', attrs={'id': 'BaltimoreOriolespitching'})
    for row in table.findAll('tr'):
        list_of_cells = []
        for cell in row.findAll('td'):
            text = cell.text.replace(' ', '')
            list_of_cells.append(text)
        for list in list_of_cells:
            with open('test1.csv', 'w', newline='') as fp:
                a = csv.writer(fp, delimiter=',')
                a.writerows(list)

具体来说，您会遇到什么错误？缩进错误：预期为缩进块最有可能出现空白错误。检查所有空格是否等于制表符（不推荐）或每个缩进级别是否正好匹配四个空格（推荐）。如果继续出现缩进错误，请指出行号。

with open('test1.csv', 'w', newline='') as fp:
    csvw = csv.writer(fp, delimiter=',')

    for link in soup.find_all('a'):

        if not link.has_attr('href'):
            continue

        if link.get_text() != 'boxscore':
            continue

        url = base_url + link['href']

        response = requests.get(url)
        html = response.content
        soup = BeautifulSoup(html)

        # Scores
        table = soup.find('table', attrs={'id': 'BaltimoreOriolespitching'})
        for row in table.findAll('tr'):
            list_of_cells = []
            for cell in row.findAll('td'):
                text = cell.text.replace(' ', '')
                list_of_cells.append(text)
            for list in list_of_cells:
                    csvw.writerows(list)
