escaping - Getting correct string length in Python for strings with ANSI color codes -


I got some Python code that will print a set of automatic data in a column format, with appropriate readability ASCII escake action sequence to paint different pieces of data

I finally put each line in the form of a list, each item is columned with spacepad so that each line always has the same length in the same column. Unfortunately, when I actually print it, all the columns do not line up. I suspect it has to do with the ASCII escape sequences - because len function does not seem to recognize these: 

  & gt; & Gt; & Gt; A = '\ x1b [1m0.0 \ x1b [0m' & gt; & Gt; & Gt; Lane (A) 11> gt; & Gt; Print a 0.0

, and whenever every column has the same length according to the lane , then when printed on the screen, they are not exactly the same length.

There was no way to save some hackery with regular expression (which I did not rather have it) to avoid the string and to figure out what printed length then the space pad I have to do it appropriately? Maybe someone brought it back to "string" and traced its length?

Paipring wiki including matching the ANSI escape sequences: 

 < code> ESC = literal ( '\ x1B') = integer word (nums) escapeSeq = Combine (ESC + '[' + optional (delimitedList (int, ';')) + oneof (list (alphas)))

how to thus escape-sequence-stripper here: 

  from pyparsing import * ESC = literal ( '\ x1B') = integer word (nums) escapeSeq = Combine (ESC + '[' '+ optional (delimitedList (integer,'; ')) + oneof (list (alphas)) nonAnsiString = lambda Issues: Pressing (escapeSeq) .transformString (s) unColorString = nonAnsiString ( '\ x1B [1m0.0 \ x1B [0m') print unColorString, Lane (unColorString)

Print:

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
