只在imaplib中显示特定数量的电子邮件 [英] Only show certain number of emails in imaplib
问题描述
我下面的代码工作很好,但我测试这个测试电子邮件,它只有大约5个电子邮件。
在我的实际电子邮件帐户中,我在收件箱中至少有4k封电子邮件。
The code I have below is working great but I am testing this on a test email and it only have around 5 emails. On my actual email account I have atleast 4k emails on my inbox.
我有一种方法可以显示一定数量的电子邮件。例如,只显示前20个最新的电子邮件?然后,后说,当一个按钮被点击它将显示下20个电子邮件...
Is there a way for me to show for a certain number of emails. For example, only show the first 20 most recent emails? And then after that say when a button is clicked it will show the next 20 emails...
import sys
import imaplib
import getpass
import email
import email.header
import datetime
email_address = "email@company.net"
password = "123456"
M = imaplib.IMAP4('mail.company.net')
rows = []
try:
M.login(email_address, password)
print "LOGIN SUCCESS!"
except imaplib.IMAP4.error:
print "LOGIN FAILED!!"
rv, data = M.select("INBOX")
rv, data = M.search(None, "ALL")
for num in data[0].split():
rv, data = M.fetch(num, '(RFC822)')
msg = email.message_from_string(data[0][1])
subj = msg['Subject']
to = msg['To']
frm = msg['From']
body = msg.get_payload()
print subj, " ", to, " ", frm, " ", body
M.close()
M.logout()
对不起,但我真的很难想出这个。最近我学到的是我可以得到电子邮件的总数
I'm sorry but I'm really having a hard time trying to figure this out. Most recent I learned is that I can get the total number of emails
num_msgs = int(data[0])
print 'You have a total of %d messages' % num_msgs
如果 id_list [-1]
可以得到最新的电子邮件ID,我可以做类似 id_list [-1] + 19
获取最近的20封电子邮件?
And if id_list[-1]
can get the latest email id, can i do something like id_list[-1] + 19
or something so it can get the 20 most recent email?
我真的很感激任何帮助,如何实现我想要的输出。
I would really appreciate any help on how to achieve my desired output. Thank You.
到目前为止,我有
ids = data[0]
id_list = ids.split()
latest_email_id = id_list[-1] #gets most recent email
for i in latest_email_id:
if i > 21:
rv, data = M.fetch(num, '(RFC822)')
msgrecent = email.message_from_string(data[0][1])
subjs = msgrecent['Subject']
print "only print 20 most recent email"
print subjs
else:
print "none"
我如何修改这个来获得我需要的输出?
谢谢
How can i modify this to get the output i need? Thank you
最新更新:
我将代码更新为以下内容:
I updated the code to the following:
ids = data[0]
id_list = ids.split()
for num in id_list[0:10]:
rv, data = M.fetch(num, '(RFC822)')
msg = email.message_from_string(data[0][1])
subj = msg['Subject']
to = msg['To']
frm = msg['From']
body = msg.get_payload()
print subj
first
second
third
fourth
.
.
.
.
tenth
所以我想我添加 -1
,以便按照降序排序
so i figured i add -1
so that it will sort in descending order
ids = data[0]
id_list = ids.split()
for num in id_list[0:10:-1]:
rv, data = M.fetch(num, '(RFC822)')
msg = email.message_from_string(data[0][1])
subj = msg['Subject']
to = msg['To']
frm = msg['From']
body = msg.get_payload()
print subj
但是当我这样做,我没有得到任何输出。
but when i did that, i didn't get any output.
有关如何解决这个问题的任何想法?
谢谢
Any idea on how i can fix this? Thank You
推荐答案
我只是意识到我已经有了我想要的输出,指定数量的电子邮件。
I just realized that I already have the output that I want, which is to only output a specified number of emails.
ids = data[0]
id_list = ids.split()
for num in id_list[0:10]:
rv, data = M.fetch(num, '(RFC822)')
msg = email.message_from_string(data[0][1])
subj = msg['Subject']
to = msg['To']
frm = msg['From']
body = msg.get_payload()
print subj
其中 id_list [0:10]:
将在我的收件箱中输出前10封电子邮件。如果我需要输出20,它可以修改为 id_list [0:20]
我有另一个问题,但我会问一个不同的职位。但到目前为止,我有一半的需要,所以我将在这里发布我的解决方案。
Wherein id_list[0:10]:
will output the first 10 email in my inbox. If i need to output 20, it can be modified to id_list[0:20]
I have another issue but I will ask that on a different post. But so far, I have half of what I need so I will post my solution here.
