Say I have a class:  class myM():     def __init__(self):         print("original")   I then instantiate this class  a=myM() From which I can call  a.__init__() However, if I use the class itself to call __init__, myM.__init__() results in an error.  These 2 options work however: myM.__init__(myM) and myM.__init__(a) where a=myM().  Question:  Why do I have to pass myM or a as an argument to __init__, for myM.__init__ to work?  Why dont I need to do that if I call a.__init__() instead?
What is the difference between the following class methods?  Is it that one is static and the other is not?  class Test(object):   def method_one(self):     print "Called method_one"    def method_two():     print "Called method_two"  a_test = Test() a_test.method_one() a_test.method_two()
It seems "See votes, expandable user card" goes on a second line on the activity page of the user profile resulting in a pretty bad look:    You can see it live on  (though of course that may change any day now depending on their rep-growth).

I'm studying molecular biology and I'm trying to understand an experiment which shows the importance of promoters in the relative transcription level (RT). The image below comes from Rolf Knippers' book "Molekulare Genetik" (8th edition).    The legend says (among other things):     Die erste Zeile gibt die normale "Wildtyp"-Sequenz der 5'-flankierenden Region wieder.   Which, in english, means something like:     The first line repeats the normal wild-type sequence of the 5' flanking region.   The column on the right gives the relative transcription (RT) level, 1.0 being the highest possible level of transcription. As we can see, the lines where some parts of the "5' region" have been deleted give quite low RT levels, since some regions of the promoter are missing.  My questions are the following:  1) According to  and , I understand that RNA polymerase reads and uses both coding and non-coding strands in order to synthesize RNA. Therefore, how did they manage to use the sequences strands regions had been deleted to make a polymerase "read them" and perform transcription?  2) If the polymerase reads the template strand in the 3' -> 5' sense, shouldn't we talk of "ATAT box" or "TAAC box" instead of "TATA" or "CAAT" boxes? Does it mean that the "promoter" regions they are using on the graphic above are actually on the coding strand?  Thanks a lot for your help. So I'm getting my listItems with a Camlquery, but i want to calculate the avg of the "price" rows  This is the code I've used so far:  function VisaLista() {     namn = document.getElementById("txtNamn");     var camlQuery = new SP.CamlQuery();     camlQuery.set_viewXml(     "&lt;Where&gt;" +     "&lt;And&gt;" +     "&lt;Eq&gt;&lt;FieldRef Name='Title'/&gt;&lt;Value Type='Text'&gt;" + namn + "&lt;/Value&gt;&lt;/Eq&gt;" +     "&lt;Or&gt;" +     "&lt;Eq&gt;&lt;FieldRef Name='Prioritet'/&gt;&lt;Value Type='Text'&gt;Hög&lt;/Value&gt;&lt;/Eq&gt;" +     "&lt;Eq&gt;&lt;FieldRef Name='Status'/&gt;&lt;Value Type='Text'&gt;Startad&lt;/Value&gt;&lt;/Eq&gt;" +     "&lt;/Or&gt;" +     "&lt;/And&gt;" +     "&lt;/Where&gt;");     listItems1 = list.getItems(camlQuery);     clientContext.load(listItems1);     clientContext.executeQueryAsync(OnSuccessVisa, OnFail); } function OnSuccessVisa() {     var listEnumerator = listItems1.getEnumerator();     var elmt = 0;     while (listEnumerator.moveNext()) {         var currentItem = listEnumerator.get_current();         elmt = (currentItem.get_item('_x0072_zb6'));          var sum = 0;         for (var i = 0; i &lt; elmt.length; i++) {             sum += parseInt(elmt[i], 10);         }          var avg = sum / elmt.length;          document.write("The sum of all the elements is: " + sum + " The average is: " + avg);     }     $("#Kategori1").text = "Medelvärdet för dessa ordrar: " + avg }   I am getting following error     "Cannot get the value length of null - at elmt, line 43 What is an alternative to execfile in Python 3?

What looks the most professional? How about special considerations for different areas of work (e.g. in academia)? Note: This question is specifically about installed, desktop software. There is  specifically about free cloud-based software and services.  What free programs should every GIS user have installed?  I'm not necessarily referring to ESRI extensions or open-source products, but others that increase your productivity and ability to handle GIS tasks.  For example:    for writing code snippets or editing XMLs.  or  for quick graphic editing. I use  daily and I think it's worth mentioning. It's not GIS-specific, but it's a great tool, especially if used independently and on multiple projects where purchasing time-management software isn't reasonable. While it's not focused on GIS development,  has proven to be very useful in terms of increasing productivity and monitoring system resources. I have created a GIS "sidebar" on my desktop that holds all of my development tools, as well as links to the online resources I used the most. It's nice to be able to use one location, rather than many (e.g. taskbar, bookmarks in browser, search engine). PDF upload silently fails I dunno since when, but upload of PDF images fails, this hurts especially on tex.SE.
