Re: [Tutor] Interacting with stderr

Ok, i understand the dangers of using root. I will bring this to the attention of the CTO of the company, which he should know already, but none the less. You must know though, I do not have the power to change the way things are done. If he says "ahhh, dont worry about it," then what am I to do

Re: [Tutor] PySide 1.2.2 and Python 3 - "native Qt signal is not callable"

As the error message suggests, the problem might be near line 40. Look at lines 40 and 41 in your program. print(rates[row[0]] + " / VALUE : " + str(value)) rates[row[0]] = value Look at it very carefully, and try to explain to yourself what those two lines mean.

Hi Juan, Wait, you are working with a CSV file, right? You should not be trying to parse this by hand if you can avoid it: there's a 'csv' parser library in the Standard Library. https://docs.python.org/3.1/library/csv.html So: import codecs import urll

Re: [Tutor] PySide 1.2.2 and Python 3 - "native Qt signal is not callable"

Hi Juan, Take out your try/except block. It's "lying" in the sense that what's problematic isn't the failure to download. The exception handling is not doing well: it's hiding the true cause of the problem. After you take the exception handler out, try again. The error message should be a lot

[Tutor] interacting with stderr

Here is my working code. It works great in the lab, but I still need to test it on a live system. I also need to add the email notifications to it, but I purposely left them out for now; I will also adjust the sleep time to a more appropriate amount. Anyone see any issues with it or ways to make it

Re: [Tutor] PySide 1.2.2 and Python 3 - "native Qt signal is not callable"

I analyzed the code and found two mistakes: 1. I wrote 'startsWith', and not 'startswith' 2. I forgot to encode, I needed to use '.read().decode("utf-8")' rather than '.read()' only. This way I get the text correctly (http://pastebin.com/qy4SVdzK). I'm still analyzing the code and fixing things,

Ops, I'm sorry, didn't know about that, anyway I already fixed the issue. I was doing 'self.fromComboBox.currentIndexChanged().connect(self.update_ui)' instead of 'self.fromComboBox.currentIndexChanged.connect(self.update_ui)' - no parenthesis. Now the problem is another one... And NOT related to
