问题 I use a MS SQL express db. I can connect and fetch data. But inserting data does not work: cursor.execute("insert into [mydb].[dbo].[ConvertToolLog] ([Message]) values('test')") I get no error but nothing is inserted into the table. Directly after I fetch the data the inserted row is fetched. But nothing is saved. In MS SQL Server Management Studio the insertion does work. 回答1: You need to commit the data. Each SQL command is in a transaction and the transaction must be committed to write the

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 5 years ago . I'd like to parse a simple, small XML file using python however work on pyXML seems to have ceased. I'd like to use python 2.6 if possible. Can anyone recommend an XML parser that will work with 2.6? Thanks 回答1: If it's small and simple then just use the standard library: from xml.dom.minidom import parse doc =

问题 Is it possible to execute an arbitrary number of commands in sequence using the same subprocess command? I need each command to wait for the previous one to complete before executing and I need them all to be executed in the same session/shell. I also need this to work in Python 2.6, Python 3.5. I also need the subprocess command to work in Linux, Windows and macOS (which is why I'm just using echo commands as examples here). See non-working code below: import sys import subprocess cmds = [

问题 Does anyone have a simple example using ast.NodeVisitor to walk the abstract syntax tree in Python 2.6? The difference between visit and generic_visit is unclear to me, and I cannot find any example using google codesearch or plain google. 回答1: ast.visit -- unless you override it in a subclass, of course -- when called to visit an ast.Node of class foo , calls self.visit_foo if that method exists, otherwise self.generic_visit . The latter, again in its implementation in class ast itself, just

问题 I'm working on a project which involves sending data over TCP. Using the ThreadedTCPServer I'm able to do that already. The server thread only needs to read incoming strings of data and set the value of variables. Meanwhile I need the main thread to see those variables changing value. Here's my code so far, just modified from the ThreadedTCPServer example: import socket import threading import SocketServer x =0 class ThreadedTCPRequestHandler(SocketServer.BaseRequestHandler): def handle(self)

问题 This question already has answers here : Store output of subprocess.Popen call in a string (14 answers) Closed last year . I want to run a command in pythong , using the subprocess module, and store the output in a variable. However, I do not want the command's output to be printed to the terminal. For this code: def storels(): a = subprocess.Popen("ls",shell=True) storels() I get the directory listing in the terminal, instead of having it stored in a . I've also tried: def storels():

问题 How can I get the class that defined a method in Python? I'd want the following example to print " __main__.FooClass ": class FooClass: def foo_method(self): print "foo" class BarClass(FooClass): pass bar = BarClass() print get_class_that_defined_method(bar.foo_method) 回答1: import inspect def get_class_that_defined_method(meth): for cls in inspect.getmro(meth.im_class): if meth.__name__ in cls.__dict__: return cls return None 回答2: Thanks Sr2222 for pointing out I was missing the point...
