#93087 — Why does the unit test fail of the pyPDF2 package?

Hi,
I want to learn some coding on PDF. After I download and install pyPDF2,
it cannot pass unit test, which is coming from the package.

I put a screen shot link here to show the console message:

http://tinypic.com/view.php?pic=fbdpg0&s=8#.VYre8_lVhBc

[IMG]http://i57.tinypic.com/fbdpg0.png[/IMG]


This Windows 7 PC has both Python 2.7 and Enthought Canopy (3.4?) installed.

I don't know whether it has conflicts or not.


Thanks,

Please don't use screen shots:

(1) We cannot copy and paste text from a screen shot.

(2) Blind people and those with poor vision may not be able to see the
screen shot, and their screen readers do not work on images.

(3) People may be reading your post via email or news, and not be able to
access the website containing the screen shot.

Instead, copy and paste the text from the console and include it in the body
of your message. Do you know how to copy text from the Windows console?

Have you read the test failure? It is obvious why it failed. Your test
expects to get:

"TheCrazyOnesOctober14,1998Herestothecrazyones..."

but instead gets:

"TheCrazyOnes\nOctober14,1998\nHerestothecrazyones..."

The difference is obvious. Your expected output doesn't include newlines.

Thanks, Steven. I don't know how to copy command console window contents 
to the forum post. I even try redirection hoping to screen contents to a 
text file, but it fails.


Yes, there are extra '\n' in the extracted, but I don't know how to suppress
it. Does anyone know how to make it the same of the expected?

Thanks,

You can make a rectangular selection by dragging over the console
window the mouse pointer.

An alternative is to install ConEmu and set up a startup.txt file.  My 
heavily encrypted :) version follows

cmd /F:ON /T:02 /K cd C:\Users\Mark\Documents\MyPython 
"-new_console:t:MyPython"
cmd /F:ON /T:02 /K cd c:\Users\Mark\pythonissues "-new_console:t:Python 
Issues"
cmd /F:ON /T:02 /K cd c:\cPython\PCBuild "-new_console:t:cPython"
cmd /F:ON /T:02 /K cd C:\Users\Mark\Documents\Cash\Python 
"-new_console:t:Cash Python"
C:\Python34\Scripts\ipython.exe --matplotlib "-new_console:t:iPython"

Once you've overcome the encryption life is far, far easier on Windows. 
  You can do really advanced concepts like cut and paste relatively 
easily, but please don't take my word for it, try it yourself.

I don't know either, because I don't use Windows, but you can google for
instructions:

https://duckduckgo.com/html/?q=copy+text+windows+console

https://startpage.com/do/search?q=copy+text+windows+console

http://www.bing.com/search?q=copy+text+windows+console

http://au.search.yahoo.com/search?p=copy+text+windows+console

Even Google works:

Where you enter the expected output, instead of entering:

"TheCrazyOnesOctober14,1998Herestothecrazyones..."

instead enter:

"TheCrazyOnes\nOctober14,1998\nHerestothecrazyones..."


The point is that your expected output should contain the text actually in
the PDF file. If your expected output is different from the actual
contents, then the expectations are wrong, not your code. The test itself
is buggy.

You can make a rectangular selection by dragging over the console 
 window the mouse pointer. 

Excuse me. I don't understand your idea. On the command window, there is
no content copied through a mouse click/drag (even no screen difference).
Do you mean using Snipping Tool? That will be an image, which is not
advised as a previous poster.
Thanks,

Right-click the command window title bar and select Edit -> Mark.
Then use the mouse to select a rectangular area of text.
Then right-click the title bar again and select Edit -> Copy.

Click on the icon at the top-left of the command window.
Choose "Edit->Mark". Drag to select the text you want.
Click the menu again, and choose "Edit->Copy".

Thanks for the trick! I know now how new I am to the Windows.

Below is the installation message, and the unittest message.

Suspecting there are differences between Linux and Windows on '\n', I
 install pyPDF2 on Ubuntu. It has the same error. What the hell of pyPDF2
 is? I don't know what use/purpose of its test script for. This process is
 also for my learning on Python. Does anyone have the same or different 
 experiences on pyPDF2?

Thanks again.
