To build it locally, you'll need to setup your build environment. The packages build-essential, python3-dev, python3-setuptools, and libgmp-dev should suffice. Once everything is setup, simply run the following: sudo easy_install3 --verbose pycrypto On My Debian system it installs to /usr/local/lib/python3.2/dist-packages/. You can also run the self tests: >>> import sys >>> import Crypto.SelfTest >>> Crypto.SelfTest.run(verbosity=1, stream=sys.stdout) For me it ran 1078 tests (one dot per test). ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

[Tutor] Python Project
Hello Tutor, My name is darren and I'm new to this python subject but I'm a quick and persistent learner. I'm trying to do a presentation with rst2Reveal using html5 and to tell you the truth it's not that simple. So far I wrote the rst file and there is a rst2Reveal webpage with all the needed docs. [https://bitbucket.org/adimascio/rst2reveal/src] My problem is that I don't know what to do first. I'm using python 2.7. I have my repo on bitbucket. I have the images I want to use. I have my rst file. I need to know the steps I need to do to get this presentation up and running. I even started my python script??? I think??? #!c:/Python27/python.exe def main(): print "Content-type: text/html" print print "" print "Scrum Presentation" print "" print "Hello World" print "" #?? if _name_=="_main_":.0 Any way, I think this is all that I have as now. I've search the web and got lots of info. But still there is the fact that I need to know the steps exactly for me to finish this . Or at leat get the web page up and running. Any andall help will be appreciated.

[Tutor] Parsing a multi-line/record text file
Hello,
I am trying to parse a text file with a structure that looks like:
[record: Some text about the record]
Attribute 1 = Attribute 1 text
Attribute 3 = Attribute 3 text
Attribute 4 = Attribute 4 text
Attribute 7 = Attribute 7 text
[record: Some text about the record]
Attribute 1 = Attribute 1 text
Attribute 2 = Attribute 2 text
Attribute 3 = Attribute 3 text
Attribute 4 = Attribute 4 text
Attribute 5 = Attribute 5 text
Attribute 6 = Attribute 6 text
[record: Some text about the record]
Attribute 2 = Attribute 2 text
Attribute 3 = Attribute 3 text
Attribute 7 = Attribute 7 text
Attribute 8 = Attribute 8 text
Etc.for many hundreds of records
I am looking to create output that looks like:
Attribute 1 text | Attribute 3 text
Attribute 1 text | Attribute 3 text
Blank | Attribute 3 text
Treating each record as a record with its associated lines is the holy grail
for which I am searching, yet I seem to only be coming up with dead parrots.
It should be simple, but the answer is eluding me and Google has not been
helpful.
Pathetic thing is that I do this with Python and XML all the time, but I
can't seem to figure out a simple text file. I 'm missing something simple,
I'm sure. Here's the most I have gotten to work (poorly) so far - it gets
me the correct data, but not in the correct format because the file is being
handled sequentially, not by record - it's not even close, but I thought I'd
include it here:
for line in infile:
while line != '\n':
Attribute1 = 'Blank'
Attribute3 = 'Blank'
line = line.lstrip('\t')
line = line.rstrip('\n')
LineElements = line.split('=')
if LineElements[0] == 'Attribute1 ':
Attribute1=LineElements[1]
if LineElements[0] == 'Attribute3 ':
Attribute3=LineElements[1]
print("%s | %s\n" % (Attribute1, Attribute3))
Is there a library or example I could be looking at for this? I use lxml
for xml, but I don't think it will work for this - at least the way I tried
did not.
Thank you,
Marc

So the record delimiter starts with a left bracket, in first column?
And all lines within the record are indented? Use this fact.

I don't think any existing library will fit your format, unless you
happen to be very lucky.
What you probably want is to write a generator function that gives you a
record at a time. It'll take a file object (infile) and it'll yield a
list of lines. Then your main loop would be something like:
for record in records(infile):
attrib1 = attrib2 = ""
for line in record:
line = strip(line)
line_elements = line.split("=")
etc.
here you print out the attrib1/2 as appropriate
I'll leave you to write the records() generator. But the next() method
will probably play a part.
