I have installed Python 3.4.4 on XPSP3 and am trying to work my way through this tutorial. A Complete Tutorial on Ridge and Lasso Regression in Python http://www.analyticsvidhya.com/blog/2016/01/complete-tutorial-ridge-lasso-r… In Step 2 "Why Penalize the Magnitude of Coefficients?" we are shown this code: #Importing libraries. The same will be used throughout the article. import numpy as np import pandas as pd import random import matplotlib.pyplot as plt %matplotlib inline I get an error on the last line. I am running this code in Idle Python 3.4.4 Shell... Python 3.4.4 (v3.4.4:737efcadf5a6, Dec 20 2015, 19:28:18) [MSC v.1600 32 bit (Intel)] on win32 Type "copyright", "credits" or "license()" for more information. >>> import numpy as np >>> import pandas as pd >>> import random >>> import matplotlib.pyplot as plt >>> %matplotlib inline SyntaxError: invalid syntax What am I doing wrong? Suggested reading? TIA, Mike

Here are snippets from my code, perhaps something will stand out to you? to = 'ed(a)domain.gov' cc = 'ed(a)gmailmail.com' bcc = 'ed(a)home.net' msg = MIMEMultipart() msg['To'] = to msg['Cc'] = cc msg['Subject'] = 'My Subject text here' msg['From'] = 'edsboss(a)domain.gov' smtp = SMTP("smtpserver") smtp.ehlo() smtp.sendmail(msg['From'], [to, cc, bcc], msg.as_string()) Thanks in advance..hope you're still out there!! ~Ed

Skip: being you a Python old timer, I think you are just grumbling for no good reason. :) Before anything else, people are already jumping into implementation details, optimization, syntax, etc. I am barely starting to look at whether there have been previous existing efforts, and if so, why were they discarded, etc. > > What exactly have you given me that I couldn't have done with > > x = 1 > x += 1 > I come back again to repeat it one more time: the compile() function already exists and works in Python. Before you do your posting, please think about the compile() function first. (Do I need to say it one more time? I don't mind.) So, let me try to pretend I am Skip Montanaro, and follow through with the process. (a) OK, I have been told that compile() function exists in Python. (b) I am complaining that I can do x = 1 x += 1 without resorting to codeblocks. So there is no need for codeblocks. Codeblocks are useless, good for nothing. (c) OK, one more time, I have been told that compile() function exists and works in Python. Everytime I talk about codeblocks, I need to think about the compile() function first. (d) Aha! So by analogy, there is no need for the compile() function in Python. I get it now! (e) Wait a second... searching through the Python newsgroup archive I find hundreds if not thousands of messages related to the usage of the compile() function. So the compile() function can't be useless. Either thousands of Python users are wrong, or I have not been careful in my thinking process. (f) Hmm... let me look at those messages and try to understand how people are using the compile() function. (g) Aha! The compile() function is not useless. I know how to use it, now. (h) Aha! Codeblocks are not useless. (i) Aha! So codeblocks are analogous to the compile() function, the only difference is that codeblocks are compiled at compile time. The compile function compiles the code string at runtime. (j) Wait, I think Hung Jung has said everything before in his messages. Bingo! Now you get it. Hung Jung

Pickle file and send via socket
by S.B Feb. 18, 2022

Feb. 18, 2022

Hello friends Does anyone know if it's possible to pickle and un-pickle a file across a network socket. i.e: First host pickles a file object and writes the pickled file object to a client socket. Second host reads the pickled file object from the server socket and un-pickles it. Can anyone provide a simple code example of the client and server sides? Thanks

Re: Compute working days

How about: from datetime import date, timedelta # Define the weekday mnemonics to match the date.weekday function (MON, TUE, WED, THU, FRI, SAT, SUN) = range(7) def workdays(start_date, end_date, whichdays=(MON,TUE,WED,THU,FRI)): ''' Calculate the number of working days between two dates inclusive (start_date <= end_date). The actual working days can be set with the optional whichdays parameter (default is MON-FRI) ''' delta_days = (end_date - start_date).days + 1 full_weeks, extra_days = divmod(delta_days, 7) # num_workdays = how many days/week you work * total # of weeks num_workdays = (full_weeks + 1) * len(whichdays) # subtract out any working days that fall in the 'shortened week' for d in range(1, 8 - extra_days): if (end_date + timedelta(d)).weekday() in whichdays: num_workdays -= 1 return num_workdays

Strange terminal behavior after quitting Tkinter application
by Chris Nov. 4, 2020

Nov. 4, 2020

Hi, I'm puzzled by some strange behavior when my Python/Tkinter application quits (on linux): the terminal from which I started Python is messed up. If start up python, then import the code below, then start the program with Application(), then click the Quit button, my terminal never prints anything again (such as commands I type). <code> import Tkinter import sys class Application(Tkinter.Tk): def __init__(self,**config): Tkinter.Tk.__init__(self,**config) Tkinter.Button(self,text="Quit",command=self.quit_application).pack() def quit_application(self): sys.exit() </code> Can anyone tell me what I'm doing wrong? Thanks for your help. Chris
