Python逐行写入CSV

我有通过http请求访问的数据,并由服务器以逗号分隔格式发回,我有以下代码:

site= 'www.example.com'
hdr = {'User-Agent': 'Mozilla/5.0'}
req = urllib2.Request(site,headers=hdr)
page = urllib2.urlopen(req)
soup = BeautifulSoup(page)
soup = soup.get_text()
text=str(soup)

文字内容如下:

april,2,5,7
may,3,5,8
june,4,7,3
july,5,6,9

如何将此数据保存到CSV文件中。我知道我可以按照以下方式做一些事情来逐行迭代:

import StringIO
s = StringIO.StringIO(text)
for line in s:

但我不确定如何正确地将每一行写入CSV

编辑--->感谢您提供的反馈意见,解决方案相当简单,可以在下面看到。.

解:

import StringIO
s = StringIO.StringIO(text)
with open('fileName.csv', 'w') as f:
    for line in s:
        f.write(line)

一般方式:

##text=List of strings to be written to file
with open('csvfile.csv','wb') as file:
    for line in text:
        file.write(line)
        file.write('\n')

OR

使用CSV编写器:

import csv
with open(<path to output_csv>, "wb") as csv_file:
        writer = csv.writer(csv_file, delimiter=',')
        for line in data:
            writer.writerow(line)

OR

最简单的方法:

f = open('csvfile.csv','w')
f.write('hi there\n') #Give your csv text here.
## Python will convert \n to os.linesep
f.close()

您可以像写入任何普通文件一样写入文件。.

with open('csvfile.csv','wb') as file:
    for l in text:
        file.write(l)
        file.write('\n')

如果以防万一,它是一个列表列表,你可以直接使用内置的csv模块

import csv

with open("csvfile.csv", "wb") as file:
    writer = csv.writer(file)
    writer.writerows(text)

我只想将每一行写入文件,因为它已经是CSV格式:

write_file = "output.csv"
with open(write_file, "w") as output:
    for line in text:
        output.write(line + '\n')

我不记得目前如何用换行符写行,但是:p

另外,您可能想看一下 这个答案 关于write()writelines()'\n'。.

那这个呢:

with open("your_csv_file.csv", "w") as f:
    f.write("\n".join(text))

str.join() 返回一个字符串,它是iterable中字符串的串联。元素之间的分隔符是提供此方法的字符串。.
