Pandas' loading a CSV file problem
Hi All---
I am new to Pandas. I am trying to load a csv file into pandas using
import pandas as pd
f = pd.read_csv(OSATemp.csv')
Even though I was able to read and manipulate the file in Python343, in
Pandas the file could not be loaded. When I run the above statement, I get
a series of massages such as
Traceback (most recent call last):
File "C:\Users\EK Esawi\Anaconda3\Scripts\file1.py", line 3, in
f = pd.read_csv('c:/Users/EK Esawi/My Documents/Temp/GOSATemp.csv')
File "C:\Users\EK
Esawi\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 474, in

Any help/suggestion is greatly appreciated—EKE

UNABLE TO GET IDLE TO RUN
Hello... I have tried installing both Python 2.7 and 3.5, and in both cases I cannot get IDLE to work. I received the following message both times: IDLE’s subprocess didn’t make connection. Either IDLE can’t start a subprocess or personalfirewall software is blocking the connection. I am running Norton, and disabled it, but still IDLE will not run. Any suggestions? Thank you...

Re: variable scope of class objects
On 20/10/15 22:33, jon...@mail.python.org wrote:
In your comment you mentioned that convention is to declare variables
(and constants?) in the construction (__ini__).
I would suggest that 'constants' are not 'declared' in the __init__
method body, but either as class variables or (see later) at module scope.
I am concerned that the sheer number of varialbe / constants would
make it difficult to read.
Remember that "instance variables" in Python are just name bindings to
another object which are placed in the object's dictionary.
Python is not like some other languages where you declare your object's
member variables statically and they all magically exist when you create
the object (whether you initialise them or not): none of the bindings
exist until an assignment is executed.
Therefore, you _must_ have a set of assignments which are executed to
create the object with the bindings (or "instance variables") that you
require. This is _usually_ done in __init__ with a set of assignments to
'self' - either using default values or values passed in to __init__.
You may be getting to the point where the best way to structure this is
to write your own module (rather than just a class) which you then
import from your main script. For example, you might do something like this:
mymodule.py:
CONSTANT_X = 0x99
CONSTANT_Y = 0xF00
CONSTANT_Z = "Spam"
class MyObject(object):
def __init__(self, foo, bar):
# 'foo' can be anything. 'bar' must be one of
# a specific set of values:
if bar not in (CONSTANT_X, CONSTANT_Y):
raise ValueError("Parameter 'bar'")
self.foo = foo
self.bar = bar
Then, in your main script you might do something like:
import mymodule
obj = mymodule.MyObject(100, mymodule.CONSTANT_X)
... then start calling methods on 'obj'.
So you just define your address and variable constants at module level
and import them along with any class and function definitions.

The location of upload, hosting etc is irrelevant, although the uploader and the host can both be liable along with the author.

You've missed off the critical line at the end, where it says what the
actual error is. Can you copy and paste the whole error text, please?
Also, I suspect something might have become mangled in transmission;
if you can copy and paste your code as well, and make sure you post as
plain text (not "rich text" or "HTML" or "formatted text" or anything
like that), that would help.

Is that really how this works? Ouch. > It does seem harsh, and that Gutnick case I linked to was greeted with great alarm around the world back in 2002 for the same reasons as you've raised. In fact, some predicted a new age of "libel tourism", where people would travel to countries with especially harsh laws in order to sue, and the subsequent "death of the internet". But it hasn't turned out as badly as all that. The only noticeable change has been some cautious online publishers requiring readers to register. As I mentioned, it's only an issue if the defamed has reputation and the defamer has assets in the same jurisdiction. Once you think it through, it's pretty logical. If I write a defamatory letter about you and put it in a mailbox (upload it to a server), no defamation has happened yet. If someone reads it later (downloads it) in a country where no-one has heard of you, still no defamation. If someone reads it in a country where everyone knows you, but where I have no property, then technically there is defamation but you have no way to make me pay. It's only a civil claim so it's not like I'll have a criminal record or Interpol on my tail or anything. The other reason it makes sense is the alternative. If server location determined the jurisdiction, you'd have Cayman-style "libel-havens" with super-lax laws, stacked with servers people could use to defame anyone anywhere with impunity.

Is that really how this works? Ouch. Yeah the idea of national laws being subject to some kind of internationally agreed jurisdiction is nice but has never been implemented. Since you mention the US it's worth noting that some US federal laws effectively have global jurisdiction. This means that someone anywhere in the world can be deemed to have committed a criminal offence under certain US laws even if their actions are entirely legal under local law. I have a feeling that something may have changed recently but certainly until a few years ago we used to have lots of cases of "libel tourism" in the UK. This is where someone decides to bring a libel case which has nothing to do with the UK before the UK courts because libel law here is steeped in favour of the litigant. UK law requires the case to have a connection to the UK but the courts were apparently prepared to accept very tenuous connections (presumably because the whole business could function as an "export" bringing loads of money to all the lawyers involved). AFAIK these cases usually concerned foreign newspaper websites rather than something like the archive here though. Leaving aside the issue of "defamation" the posts that have been removed here are IMO "spam" and it's entirely reasonable to remove them regardless of any legal issues. -- Oscar -- https://mail.python.org/mailman/listinfo/python-list

Thanks, but I think this is already covered in my original post: I couldn't use it directly due to the pip installation restriction. I've now created a working Windows implementation, so I don't need another mapping for win32. More generally, as these posts begin to show, there was no _simple_ way for me to get a cross-platform console API that "just worked" out of the box. I've had to jump through various hoops to get to where I am and don't think that other people should have to go through the same pain as I have. This is one of the reasons why I've been tidying up my package to make this as simple as possible for the next person. I've now got to the stage where I have something that works for me, but it is almost certainly missing something. Maybe it's not good enough documentation, maybe there's some clunkiness left in the API due to the history of the project, maybe there's an even better way to represent terminals than what I've come up with so far?

One thing to recall is that 'who/what can be defamed' varies a lot. In Sweden you cannot defame a corporation. The defamation regulations in the Penal Code only apply to private individuals. If you cannot bleed, you cannot be defamed. In certain situations the Swedish Marketing Act may be used to stop defamation of a corporate entity -- if a rival has, without basis, tainted a rival's reputation -- but this sort of protection is limited. This makes Sweden an attractive place to discuss Mosanto, and their evil practices, even though, like a lot of places Sweden's defamation law does not have a clause saying roughly 'if it is true, it isn't defamation'. Just 'intent to villify' is enough. Laura -- https://mail.python.org/mailman/listinfo/python-list

They are used to fix naive signal handling in a main loop: while not signaled: select.poll(...) ... The loop suffers from a race condition: the "signaled" flag, which is set by a signal handler, might change between "while" and "select.poll". The standard, classic way to solve the race condition is to replace the "signaled" flag with an internal pipe. The signal handler writes a byte into the pipe and select.poll() wakes up when the pipe becomes readable. IOW, ppoll() and pselect() are not needed.

From Wikipedia: """ A court does not have jurisdiction to hear and determine any action, unless the court is satisfied that, of all the places in which the statement complained of has been published, England and Wales is clearly the most appropriate. """ https://en.wikipedia.org/wiki/Defamation_Act_2013#Jurisdiction Libel tourism cases often would occur for a foreign publication that was not distributed in printed form in the UK but had a website that was globally accessible. A case might be brought on the strength of say a hundred UK downloads from the website despite the publication having a printed circulation of hundreds of thousands in some other country (and the authors and complainants all being in the same other country). I can't recall any specific cases right now though... If the court needs to be satisfied that England and Wales is the _most_ appropriate place to hear the case then this would rule out the libel tourism cases I used to hear about. Apparently this only applies to England and Wales though leaving Northern Ireland as a new preferred location for libel tourism. -- Oscar -- https://mail.python.org/mailman/listinfo/python-list

I guess you're on Windows and your CSV file is encoded as Windows-1252. Unless
you tell Pandas this it'll assume your file is utf-8 encoded.
Try this:
f = pd.read_csv('c:/Users/EK Esawi/My Documents/Temp/GOSATemp1.csv',

For example, the US explicitly prohibits their courts from enforcing foreign libel or defamation suits unless the other country provides at least as much protection for free speech as does the US. Oh, and for what it's worth, I remember that case very well, and I think the judges were terribly naive in some of their comments. Specifically, they poo-pooed the suggestion that the ruling could lead to a flurry of defamation actions in Australia against publications all over the world. If they were right, it was more by good luck than by good reasoning: the UK, not Australia, was the go-to place for "libel tourism". https://en.wikipedia.org/wiki/Libel_tourism > On the specific point, I think it's possible to agree with both > Steven and Laura.

Standards vary greatly. It is hard to prove defamation in the US, it was ridiculously easy in the UK (things are better since the Simon Singh case inspired the UK government to change the law), and in places like Singapore defamation is a thinly disguised weapons for the ruling party to use to attack political opponents and critics, and protect themselves from having their corrupt activities revealed. http://singaporepress.pbworks.com/w/page/11489265/Defamation%20Act http://www.irrawaddy.org/asia/in-singapore-the-economics-of-defamation.html http://singaporedissident.blogspot.com.au/2012/02/lee-family-will-not-sue-for-defamation.html http://www.singapore-window.org/sw02/020926au.htm Including ordinary bloggers: http://blogs.wsj.com/indonesiarealtime/2014/06/04/libel-suit-turns-singapore-blogger-into-underdog-for-pensioners/ -- Steven -- https://mail.python.org/mailman/listinfo/python-list

This is my code:* print "Installing APK" for apk in glob.glob(self.apkfolder + '/*.apk'): try: self.device.installPackage(apk) except IOError, error: print "Error Message " print(error) But It’s not working. Some ideas? I'm using Ubuntu 14.04 Thanks! -- Att. *Isabel Karina* -- https://mail.python.org/mailman/listinfo/python-list

See if the program works anyway without _fastmath. It would use the built-in Python arithmetic which is slower but usable unless you have high performance requirements. According to my benchmarks (a long time ago on a 32-bit x86) GMP was about 4x faster than Python's bigints. But your program isn't likely to spend that much of its time doing bignum math. -- https://mail.python.org/mailman/listinfo/python-list
