[Tutor] python + sharepoint
Can someone assist in a very basic task of retrieving a '.txt' file from a sharepoint document library using Python 2.4 standard libraries? I'm certain, I need to build up some form of authentication to pass, but do not know where to begin. Also, I do not want to attempt to customize or install additional packages to the server for this (Solaris).

[Tutor] number of mismatches in a string
Hi: I have the following table and I am interested in calculating mismatch ratio. I am not completely clear how to do this and any help is deeply appreciated. Length Matches 77 24A0T9T36 71 25^T9^T37 60 25^T9^T26 62 42A19 In length column I have length of the character string. In the second column I have the matches my reference string. In fist case, where 77 is length, in matches from left to right, first 24 matched my reference string following by a extra character A, a null (does not account to proble) and extra T, 9 matches, extra T and 36 matches. Totally there are 3 mismatches In case 2, I lost 2 characters (^ = loss of character compared to reference sentence) - TOMISAGOODBOY T^MISAGOOD^OY (here I lost 2 characters) = I have 2 mismatches TOMISAGOOODBOOY (here I have 2 extra characters O and O) = I have two mismatches In case 4: I have 42 matches, extra A and 19 matches = so I have 1 mismatch How can that mismatch number from matches string. 1. I have to count how many A or T or G or C (believe me only these 4 letters will appear in this, i will not see Z or B or K etc) 2. ^T or ^A or ^G or ^C will also be a mismatch desired output: Length Matches mismatches 77 24A0T9T36 3 71 25^T9^T37 2 60 25^T9^T26 2 62 42A19 1 10 6^TTT1 3 thanks Hs. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Length Matches
77 24A0T9T36
71 25^T9^T37
60 25^T9^T26
62 42A19
In length column I have length of the character string.
In the second column I have the matches my reference string.
In fist case, where 77 is length, in matches from left to right, first 24
matched my reference string following by a extra character A, a null (does
not account to proble) and extra T, 9 matches, extra T and 36 matches.
Totally there are 3 mismatches
In case 2, I lost 2 characters (^ = loss of character compared to reference
sentence) -
TOMISAGOODBOY
T^MISAGOOD^OY (here I lost 2 characters) = I have 2 mismatches
TOMISAGOOODBOOY (here I have 2 extra characters O and O) = I have two
mismatches
In case 4: I have 42 matches, extra A and 19 matches = so I have 1 mismatch
How can that mismatch number from matches string.
1. I have to count how many A or T or G or C (believe me only these 4
letters will appear in this, i will not see Z or B or K etc)
2. ^T or ^A or ^G or ^C will also be a mismatch
desired output:
Length Matches mismatches
77 24A0T9T36 3
71 25^T9^T37 2
60 25^T9^T26 2
62 42A19 1
10 6^TTT1 3
It looks like all you need to do is count the number of A, T, C, and G
characters in your Matches column. Maybe something like this:
differences = [
[77, '24A0T9T36'],
[71, '25^T9^T37'],
[60, '25^T9^T26'],
[62, '42A19']
]
for length, matches in differences:
mismatches = 0
for char in matches:
if char in ('A', 'T', 'G', 'C'):
mismatches += 1
print length, matches, mismatches
which produces the following output:
77 24A0T9T36 3
71 25^T9^T37 2
60 25^T9^T26 2
62 42A19 1

Ah.
Well that explains why your version using urllib2 failed -- you don't give a
username or password, and sharepoint (whatever that is!) requires one.
You might have said.
You can read the Fine Manual, which describes how to fetch Internet resources:
http://docs.python.org/howto/urllib2.html
That is written for Python 2.7, here's one for 2.4:
http://docs.python.org/dev/howto/urllib2.html
Since you need to authenticate, this will probably be helpful:

[Tutor] mentorship
Hello folks - I'm a little lost and seek a mentor to accelerate the learning curve associated with open-source development, with python in particular but not exclusively. I've been an computer enthusiast / amateur programmer for 20 years. Too, in the past few years I've researched a variety of related topics: historical computer culture, modern security and cryptography, Linux administration and the philosophy of software development. I also have some working knowledge of apache, website design and a compsci degree from 10 years ago. NOW WHAT? HELP! I've got some free time and I feel like I should pick an open source project and begin contributing, but the options are just staggering. I've narrowed things down to the Python language - maybe the Plone project? maybe helping with documentation at first? Maybe testing? I welcome any suggestions on any point or question given. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
