Error writing data to CSV due to ascii error in Python

问题

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


base_url = 'http://www.baseball-reference.com'
data = requests.get("http://www.baseball-reference.com/teams/BAL/2014-schedule-scores.shtml")
soup = BeautifulSoup(data.content)
outfile = open("./Balpbp.csv", "wb")
writer = csv.writer(outfile)

url = []
for link in soup.find_all('a'):

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

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

    url.append(base_url + link['href'])

for list in url:
    response = requests.get(list)
    html = response.content
    soup = BeautifulSoup(html)


    table = soup.find('table', attrs={'id': 'play_by_play'})

    list_of_rows = []
    for row in table.findAll('tr'):
        list_of_cells = []
        for cell in row.findAll('td'):
            text = cell.text.replace('&nbsp;', '')
            list_of_cells.append(text)
        list_of_rows.append(list_of_cells)
    writer.writerows(list_of_rows)

u'G.\xa0Holland', u'N.\xa0Cruz'...

Here is the error message:

Traceback (most recent call last):
  File "try.py", line 40, in <module>
    writer.writerows(list_of_rows)
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 57: ordinal not in range(128)

When I write the data to a csv I end up with data that contains \x... stuff in the data pieces which prevents the data from being written to a csv. How could I change the data to delete this part of the data or do something to circumvent this issue?

回答1:

You cannot use unicode with the csv module with python2, you need to encode the strings:

Note

This version of the csv module doesn’t support Unicode input. Also, there are currently some issues regarding ASCII NUL characters. Accordingly, all input should be UTF-8 or printable ASCII to be safe; see the examples in section Examples.

text = cell.text.replace('&nbsp;', '').encode("utf-8")

Output after encoding:
