[Tutor] Query about getattr used as a dispatcher
i am following 'dive into python' for learning. i come across a term getattr() which gives reference about a function.Its written it can be used as a dispatcher. Below example given for that builtin function: import statsout def output(data,format='text'): output_function = getattr(statsout,"output_%s" % format) return output_function(data) Actually i installed python 2.5 i ran this script and its showing error it could not import statsout.why is it so?could any one explain this script briefly. i dont know whether i am following the right book. as i am a beginner is it right to follow this book?or is there any other book which is best for beginners? -- Vanam ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Difference between 'yield' and 'print'
Is there any difference between yield and print in python script?i have written a script based on fibonacci series where in i used yield and print in two different scripts: the script is given below: def fib(n): a,b = 0,1 while a<=n: print a a,b = b,a+b for x in fib(4): print x. When i executed this script i am getting this error: Typeerror:"nonetype" is not iterable But the same script if 'print' is replaced with 'yield' inside while loop it is executing properly without any type errors could any one reply why print cant be used instead of yield and why error is generated? -- Vanam ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Question on joining out of order dictionary elements
Hi everyone,
I have a quick quick question joining out of order dictionary values.
For example:
I created an empty
config={}
Added some key/value pairs
config["test1"]="elem1"
config["test2"]="elem2"
config["test3"]="elem3"
etc
Dumped the values and joined them at the same time.
print "\\".join(config.values())
elem1\elem3\elem2
This is fine but it doesn't entirely solve the issue.
Only some of the key/value pairs in the dictionary are needed so a
dump of all values does not work.
Also, the order in which the values are joined is important so walking
through and joining all values does not work either.
The simplest way would be to do something like:
print "\\".join((config["val2"],config["val1"],config["val3"]))
elem2\elem1\elem3
or
print "%s\\%s\\%s" % (config["val2"],config["val1"],config["val3"])
elem2\elem1\elem3
but this seems somehow uneligent.
Are there a more efficient/compact ways of doing this kind of
operation or is this it?
The key/value pairs in these examples are contrived for purposes of
this discussion but the end goal is to piece together server and
directory path information for use with pysvn.
I have a Perl programmer who is learning Python and he is griping that
this kind of operation is far simpler in Perl.
To print or to retain individual values from a list,it has to be written in
the form of
config={'test1':'elem1','test2':'elem2','test3':'elem3'}
config['test4'] = 'elem4'
print config.values()
print config['test1']- To get individual values from a list
If we want to retrieve all the values or say 2 from 4 its not possible to
put in a while loop and get that as a list only takes one argument at a time
better way is to extract individually and respective keys could not be
obtained if corresponding values are given.

Hi All,
I am playing with reportlab and I would like to make a directory where I
can place all of my projects as ___.py files.
A project file should be like this:
test.py
title="Test project"
duedate = '2007-02-28'
description = "description _"
detailed="""
detaileddetaileddetaileddetaileddetaileddetaileddetailed
detaileddetaileddetaileddetaileddetaileddetaileddetailed
detaileddetaileddetaileddetaileddetaileddetaileddetailed
detaileddetaileddetaileddetaileddetaileddetaileddetailed
detaileddetaileddetaileddetaileddetaileddetaileddetailed
"""
test.py
I plan to make a python script, that collect all the projectfiles from
that folder and render them as a report summary.
I planned to import these files as modules like
for filename in glob.glob('*.py'):
if '_' in filename: continue
import filename
render(filename)
Probably you have better ideas to do that.
Yours sincerely,
__

This won't work, the import statement does not take a variable as an
argument. You need something like
module = __import__(filename)
render(module)
You will want to take care that your modules don't have any side effects
on import.

You might want to look at the existing Python document generation tools.
There is a summary here (be sure to read the comments and the original
post just below this one):
http://www.voidspace.org.uk/python/weblog/arch_d7_2006_12_30.shtml#e599
In particular PythonDoc supports structured comments that are similar to
what you outlined and has pluggable output generators that could be used
to drive ReportLab.

... my many apologies to the readers of the tutor
list. I went away for a week without suspending delivery
just as my company changed name - and decided to send
an irritating response to anything directed at the
old name. The list admin has very properly unsubscribed
the old address (otherwise you'd be seeing loads more
of the things!). Sorry again. Hope it didn't spoil your
new year.
