sending email to distribution list using python

I'm trying to send emails to people in a distribution list in my company using python. My company uses outlook.

When I send to individual users specifying their email, it works perfectly. However I need to use the distribution list, since the recipients are updated by my IT department and I cant keep updating the email list whenever it changes.

Whomever has used outlook, you might recall that the distribution list starts with an exclamation mark like so: !groupdept@company.com

I am using the following method to send emails using python:

from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from smtplib import SMTP
import smtplib
import sys

subject = "Group Email"
fromm = 'me@company.com'
recipients = ['someone@company.com, someonelse@company.com'] 
emaillist = [elem.strip().split(',') for elem in recipients]

msg = MIMEMultipart()
msg['Subject'] = subject
msg['From'] = fromm

html = """\
<html>
<head>
</head>
<body style="font-size:18px;">
{0}
</body>
</html>
""".format(df2.style
       .set_properties(**{'border': '2.5pt solid green', 'color': 'magenta', 'font-size': '15pt'})
       .hide_index()
       .hide_columns()
       .render()
      )
message = MIMEText(html, 'html')
msg.attach(message)
server = smtplib.SMTP('00.0.0.00', 25)
server.sendmail(msg['From'], emaillist , msg.as_string())

The above method works well for comma separated recipients. However if I use !groupdept@company.com it doesn't work, which I can understand since that is an MS Outlook functionality.

Has anyone achieved this before?

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...

Sorting large arrays of big numeric stings

I was solving bigSorting() problem from hackerrank: Consider an array of numeric strings where each string is a positive number with anywhere from to digits. Sort the array's elements in non-decreasing, or ascending order of their integer values and return the sorted array. I know it works as follows: def bigSorting(unsorted): return sorted(unsorted, key=int) But I didnt guess this approach earlier. Initially I tried below: def bigSorting(unsorted): int_unsorted = [int(i) for i in unsorted] int_sorted = sorted(int_unsorted) return [str(i) for i in int_sorted] However, for some of the test cases, it was showing time limit exceeded. Why is it so? PS: I dont know exactly what those test cases were as hacker rank does not reveal all test cases. source https://stackoverflow.com/questions/73007397/sorting-large-arrays-of-big-numeric-stings
