Re: IDLE won't run after installing Python 3.3 in Windows

I had a previous 2.7 installation that I uninstalled and carefully removed all traces of from the directory and the registry. It is not necessary to uninstall previous versions of Python. They can live happily together. Not only does it work, it's a supported configuration. That's what the launcher is for. Mucking with the registry is generally inadvisable. It's too easy to make a mistake. If you do decide to uninstall a Python version, do it through the Control Panel. If that results in problems, submit a bug report. I got the 'python-3.3.3.msi' from Python.org and installed it. From a command window I can run 'python' and I get the Python prompt. I have several Python programs on the machine. If I right click o one, I have the option of 'Edit in IDLE'. If I do that, the disk light blinks briefly, and then nothing. So I went into the \python33\lib\idlelib directory and from a CMD window, ran 'python idle.py'. That loads IDLE. but when I ask IDLE to load a file, it navigates to a FileOpen dialog and then closes everything when I actually open the file. I then tried the same thing but used 'pythonw' instead. Same deal. I also saw some other threads here about how Python can get befuddled by firewalls, so I disabled that with no effect. Any suggestions? Thanks in advance! I would reinstall Python2.7 and then reinstall Python3.3. That may straighten out your registry.

Re: Bytes indexing returns an int
treating bytes as chars considered harmful? I don't know the answer to your question but the behavior seems right to me. Python 3 grudgingly allows the abomination of byte strings (is that what they're called? I haven't fully embraced Python3 yet). If you want a substring you use a slice. b = b'xyz' b[1:2] = b'y' also, chr(121) = 'y' which is really what the Python 3 gods prefer.

The days of HT's usefulness in printer control are long gone, said Dr. Yishoki Makimi, chair of the subcommittee. Today tabs are only used in software source code. Our research revealed they serve no function in software engineering other than to provoke arguments and therefore waste time. We measured that HTs accumulated economic cost surpassed that of big vs. little-endian byte order in 2007 and started the committee work to deprecate it shortly after that. The width of a horizontal tab was originally adjustable in printer mechanism and was never standardized. Its subsequent use for indentation of instructions in the source code of block-oriented languages was economical when computer storage was expensive. Eventually many programmers adopted spaces leading to the contraversy that motivated the subcommittee. Microsoft has responded to ISO's move by announcing that HT will contunue be supported in Windows through Version 8, after which the code point will be repurposed for the Windows Key.

Re: I need help installing pypng in Python 3.3
On Mon, Oct 29, 2012 at 8:23 AM, ic...@tagyourself.com wrote:
Hello all,
I am very new to python. I am currently porting a little project of mine from
java to python and I need to be able to construct and write png images. I
naturally turned myself toward pypng to accomplish this.
I learned from the net that pypng 0.0.13 is supposed to work in Python 3.x
when run through '2to3'. However, in my case, it apparently does not.
You haven't shown that.
I ran into various problems when trying to install it, some of them I could
fix myself. First I attempted to install pip but I couldn't get Windows to
recognize pip as an internal command as the prompt informs me.
No, it's not an internal command, but you don't need that. I'm
assuming your python is installed under C:\Python33. If not, adjust as
needed. Try:
C:\Python33\Scripts\pip install pypng
[You didn't say what you did to install pip so I don't know if pip.exe
actually exists in C:\Python33\Scripts]
Then I tried to directly run setup.py install from the pypng folder. It
didn't work as I got a syntax error. I noticed that in the beginning of the
installation process, the following warning was displayed: conf[use_2to3 =
true] unrecognized configuration option
The following works for me:
C:\Python33\python setup.py install
At that point I was already pretty pissed but I managed to make the warning
disappear by updating (installing?) distribute. After that there are no more
errors during the installation process and everything seems to work fine.
(This seems still strange to me as 2to3 was present in Tools/Script out of
the box)
It's not clear what you did here. setup.py should run 2to3 for you.
What command did you use to successfully? install it?
I use pydev in Eclipse and pydev reports several error in png.py anytime I
want to import or use it. When trying to import from IDLE I get:
except ValueError, e:
^
Syntax error, line 1863
It's clear that the install process didn't run 2to3.
that paricular error I was able to fix by changing it to except ValueError
as e: but I don't understand why 2to3 didn't do it automatically.
2to3 does do it automatically.
There are several more errors reported by pydev, here are a few:
line 1368 : raise ValueError('Chunk %s too short for checksum.', tag)
Undefined variable: tag
Looking at the code, this appears to be a bug.
line 2736 : rows = [map(numpy.uint16, range(0,0x1,0x))]
Undefined variable from import: uint16
The second one made me suspect I needed to install numpy too. As there are no
installers for numpy aimed toward Python3.3.
A few lines above there's a try/except for importing numpy. It should
skip this test if numpy is not available. I'm not sure how you were
able to execute that line [unless you've got a stray numpy.py file
somewhere somewhere]
I decided to install Python2.7 and retry the whole process. Unfortunately I
didn't get much more success. I get the exact same errors in pydev when using
the 2.7 version of the interpreter and I cannot install numpy either because
when I run the .exe file aimed toward Python 2.7 i get the error message:
Python version 2.7 required, which was not found in the registry
I then have the option to manually enter the path to Python 2.7 but the
textform is greyed out and I can't type in anything.
Do you have the file c:\Python33\Lib\site-packages\pypng-0.0.13-py3.3.egg ?
If not, you have not successfully installed pypng. Please try one of
the methods I gave above.

Because under Windows the first call will look for the python.exe first found in the PATH while the second call will find the python.exe associated with the .py extension. And it does not matter in either case what version of the multiple installed versions of Python which are on my system is currently executing that script. And please don't say that there is some sort of guarantee that no library or installation would invoke Python in such a way as opposed to the normal 'import AScript.py' method of using functionality in Python scripts.

It can collapse different blocks of code, such as functions, classes, etc. However, I never got used to it because of the bizarre key bindings.

The boolean expression part is already evaluating to a boolean, so I don't understand why a code author would feel compelled to beat this one over the head with the additional and True or False. I did a little code Googling and found a few other Python instances of this, but also many Lua instances. I'm not that familiar with Lua, is this a practice that one who uses Lua frequently might carry over to Python, not realizing that the added and True or False is redundant? Other theories? -- Paul -- http://mail.python.org/mailman/listinfo/python-list True and False were added in Python 2.2.1 (PEP 285) Perhaps this was a silly way to ensure that the user wouldn't try to run it in earlier versions. -- http://mail.python.org/mailman/listinfo/python-list

That's because you need to promote one of them to a float so you get a floating-point result: 1/2 * 1/2 0 1/2 * 1/2.0 0.0 Oh...wait ;-) Tim, I'm sure you know the answer to this, but for the benefit of the Original Poster, the problem is that you need to promote *both* divisions to floating point. Otherwise one of them will give int 0, which gives 0.0 when multiplied by 0.5. 1.0/2 * 1/2.0 0.25 If you want an exact result when multiplying arbitrary fractions, you need to avoid floats and decimals and use Fractions: Fraction(1, 2)**2 Fraction(1, 4) I should have known he wouldn't get it. -- http://mail.python.org/mailman/listinfo/python-list
