• Idiomatic Python: 'times' loop

  - by perimosocordiae

  Say I have a function foo that I want to call n times. In Ruby, I would write: n.times { foo } In Python, I could write: for _ in xrange(n): foo() But that seems like a hacky way of doing things. My question: Is there an idiomatic way of doing this in Python?

• Python or Ruby for webbased Artificial Intelligence?

  - by Pieter Kubben

  A new web application may require adding Artificial Intelligence (AI) in the future, e.g. using ProLog. I know it can be done from a Java environment, but I am wondering about the opportunities with modern web languages like Ruby or Python. The latter is considered to be "more scientific" (at least used in that environment), but using Google there seems to be a preliminary ProLog implementation for both. Any suggestions on modern (open source) web languages (like Python or Ruby) in combination with AI?

• Using Complex datatype with python SUDS client

  - by sachin

  hi, I am trying to call webservice from python client using SUDS. When I call a function with a complex data type as input parameter, it is not passed correctly, but complex data type is getting returned correctly froma webservice call. Webservice Type: Soap Binding 1.1 Document/Literal Webserver: Weblogic 10.3 Python Version: 2.6.5, SUDS version: 0.3.9 here is the code I am using: Python Client: from suds.client import Client url = 'http://192.168.1.3:7001/WebServiceSecurityOWSM-simple_ws-context-root/SimpleServicePort?WSDL' client = Client(url) print client #simple function with no operation on input... result = client.service.sopHello() print result result = client.service.add10(10) print result params = client.factory.create('paramBean') print params params.intval = 10 params.longval = 20 params.strval = 'string value' #print "params" print params try: result = client.service.printParamBean(params) print result except WebFault, e: print e try: result = client.service.modifyParamBean(params) print result except WebFault, e: print e print params webservice java class: package simple_ws; import javax.jws.Oneway; import javax.jws.WebMethod; import javax.jws.WebService; import javax.jws.soap.SOAPBinding; public class SimpleService { public SimpleService() { } public void sopHello(int i) { System.out.println("sopHello: hello"); } public int add10(int i) { System.out.println("add10:"); return 10+i; } public void printParamBean(ParamBean pb) { System.out.println(pb); } public ParamBean modifyParamBean(ParamBean pb) { System.out.println(pb); pb.setIntval(pb.getIntval()+10); pb.setStrval(pb.getStrval()+"blah blah"); pb.setLongval(pb.getLongval()+200); return pb; } } and the bean Class: package simple_ws; public class ParamBean { int intval; String strval; long longval; public void setIntval(int intval) { this.intval = intval; } public int getIntval() { return intval; } public void setStrval(String strval) { this.strval = strval; } public String getStrval() { return strval; } public void setLongval(long longval) { this.longval = longval; } public long getLongval() { return longval; } public String toString() { String stri = "\nInt val:" +intval; String strstr = "\nstrval val:" +strval; String strl = "\nlong val:" +longval; return stri+strstr+strl; } } so, as issue is like this: on call: client.service.printParamBean(params) in python client, output on server side is: Int val:0 strval val:null long val:0 but on call: client.service.modifyParamBean(params) Client output is: (reply){ intval = 10 longval = 200 strval = "nullblah blah" } What am i doing wrong here??
