Python不会写入文件

Question

我正在尝试将一个漂亮的打印电子邮件写入.txt文件,以便我可以更好地查看我要解析的内容.

这是我的代码的这一部分:

result, data = mail.uid('search', None, "(FROM 'tiffany@e.tiffany.com')") # search and return uids instead
latest_email_uid = data[0].split()[-1]
result, data = mail.uid('fetch', latest_email_uid, '(RFC822)')
raw_email = data[0][1]

html = raw_email
soup = BS(html)
pretty_email = soup.prettify('utf-8')

f = open("da_email.txt", "w")
f.write(pretty_email)
f.close

我没有遇到任何错误,但我无法将数据写入文件.我知道数据已妥善存储在pretty_email变量中,因为我可以在控制台中将其打印出来.

有什么想法吗？

我的更新代码仍然不起作用:

result, data = mail.uid('search', None, "(FROM 'tiffany@e.tiffany.com')") # search and return uids instead
latest_email_uid = data[0].split()[-1]
result, data = mail.uid('fetch', latest_email_uid, '(RFC822)')
raw_email = data[0][1]

html = raw_email
soup = BS(html)
pretty_email = soup.prettify('utf-8')

with open("da_email.txt", "w") as f:
    f.write(pretty_email)

Answer 1

您需要调用close方法来提交对文件的更改.添加()到最后:

f.close()

或者更好的是使用with:

with open("da_email.txt", "w") as f:
    f.write(pretty_email)

它会自动为您关闭文件
