Python不会写入文件 [英] Python won't write to file
问题描述
这个部分是这个部分的内容我的代码：
result，data = mail.uid（'search'，None，（FROM'tiffany @ e。 tiffany.com'））＃搜索并返回uid而不是
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，但我无法将它写入文件。我知道这些数据是正确的存储在pretty_email变量中，因为我可以在控制台中打印出来。
有什么想法吗？
我的更新代码依然不起作用：
result，data = mail.uid（'search'，无，（FROM'tiffany@e.tiffany.com'））＃搜索并返回uid而不是
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）$ b $ pretty_email = soup.prettify（'utf-8'）
with open（da_email.txt，w）as f：
f.write（pretty_email）
您需要调用close方法来提交更改文件。添加（）到最后：
f.close（）
甚至更好的办法是使用 with ：
<$ p $开放（da_email.txt，w）为f：
f.write（pretty_email）
它会自动关闭文件给你
I am attempting to write a pretty printed email to a .txt file so i can better view what I want to parse out of it.
Here is this section of my code:
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
I am not running into any errors, but I can't get it to write the data to the file. I know that the data is properly stored in the pretty_email variable because I can print it out in console.
Any thoughts?
MY UPDATED CODE THAT STILL DOESN'T WORK:
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)
You need to invoke the close method to commit the changes to the file. Add () to the end:
f.close()
Or even better would be to use with:
with open("da_email.txt", "w") as f:
f.write(pretty_email)
which automatically closes the file for you
