• How efficient is Python substring extraction?

  - by Cameron

  I've got the entire contents of a text file (at least a few KB) in string myStr. Will the following code create a copy of the string (less the first character) in memory? myStr = myStr[1:] I'm hoping it just refers to a different location in the same internal buffer. If not, is there a more efficient way to do this? Thanks! Note: I'm using Python 2.5.

• Data aggregation mongodb vs mysql

  - by Dimitris Stefanidis

  I am currently researching on a backend to use for a project with demanding data aggregation requirements. The main project requirements are the following. Store millions of records for each user. Users might have more than 1 million entries per year so even with 100 users we are talking about 100 million entries per year. Data aggregation on those entries must be performed on the fly. The users need to be able to filter on the entries by a ton of available filters and then present summaries (totals , averages e.t.c) and graphs on the results. Obviously I cannot precalculate any of the aggregation results because the filter combinations (and thus the result sets) are huge. Users are going to have access on their own data only but it would be nice if anonymous stats could be calculated for all the data. The data is going to be most of the time in batch. e.g the user will upload the data every day and it could like 3000 records. In some later version there could be automated programs that upload every few minutes in smaller batches of 100 items for example. I made a simple test of creating a table with 1 million rows and performing a simple sum of 1 column both in mongodb and in mysql and the performance difference was huge. I do not remember the exact numbers but it was something like mysql = 200ms , mongodb = 20 sec. I have also made the test with couchdb and had much worse results. What seems promising speed wise is cassandra which I was very enthusiastic about when I first discovered it. However the documentation is scarce and I haven't found any solid examples on how to perform sums and other aggregate functions on the data. Is that possible ? As it seems from my test (Maybe I have done something wrong) with the current performance its impossible to use mongodb for such a project although the automated sharding functionality seems like a perfect fit for it. Does anybody have experience with data aggregation in mongodb or have any insights that might be of help for the implementation of the project ? Thanks, Dimitris

• Counting longest occurence of repeated sequence in Python

  - by user248237

  What's the easiest way to count the longest consecutive repeat of a certain character in a string? For example, the longest consecutive repeat of "b" in the following string: my_str = "abcdefgfaabbbffbbbbbbfgbb" would be 6, since other consecutive repeats are shorter (3 and 2, respectively.) How can I do this in Python? thanks.

• Removing non-breaking spaces from strings using Python

  - by dontsaythekidsname

  Hello: I am having some trouble with a very basic string issue in Python (that I can't figure out). Basically, I am trying to do the following: '# read file into a string myString = file.read() '# Attempt to remove non breaking spaces myString = myString.replace("\u00A0"," ") '# however, when I print my string to output to console, I get: Foo **<C2><A0>** Bar I thought that the "\u00A0" was the escape code for unicode non breaking spaces, but apparently I am not doing this properly. Any ideas on what I am doing wrong?

• Perl vs Python but with more style than normally

  - by user350571

  I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?

• Get Cygwin installation path in a Python script

  - by chris.nullptr

  I'm writing a cross-platform python script that needs to know if and where Cygwin is installed if the platform is NT. Right now I'm just using a naive check for the existence of the default install path 'C:\Cygwin'. I would like to be able to determine the installation path programmatically. The Windows registry doesn't appear to be an option since Cygwin no longer stores it's mount points in the registry. Because of this is it even possible to programmatically get a Cygwin installation path?
