[Artificial intelligence series] python Quepy library learning, pythonquepy Article 1 What is Quepy? Quepy is a Python framework to transform natural language problems in database query language queries. It can easily customize different types of problems for queries in natural languages and databases. Therefore, with very little code, you can build your own system and access your database in natural langua

.communicate () print (out)Subprocess. Pipe actually provides a buffer for text flow.The child1 stdout the text out to the buffer, and then Child2 's stdin reads the text from the pipe.The output text of the child2 is also stored in the pipe until the communicate () method reads the text from the pipe.Note that communicate () is a method of the Popen object that blocks the parent process until the child process finishes.We can also use the communicate () method to input a child process using a p

. Httperror as E: print (e.reason,e.code,e.headers) except error. Urlerror as E: print (E.reason) Else: print (' Request successfully ')Sometimes it is possible to use the socket library when reason returns a string or an object.The socket is the network connection endpoint. For example, when your Web browser requests a home page on www.jb51.net , your Web browser creates a socket and commands it to connect to the www.jb51.net Web server host

process sends itself a SIGALRM signal, and then the signal handler function MyHandler begins execution.The core of the send signal signal packet is to set the signal processing function.In addition to the Signal.alarm () sends a signal to itself, there is no other function to send the signal.In the OS package, however, there are functions similar to the Linux Kill command, respectivelyOs.kill (PID, sid)OS.KILLPG (Pgid, sid)Send signals to process and process groups (see Linux process Relationsh

element at the same time using the specified variable. For example, for the following statement from listing 16.9 of the program:For_each (Books.begin (), Books.end (), Showreview);You can replace it with the following range-based for loop:for (auto X:books) Showreview (x);Depending on the type of book (vectorUnlike For_each (), a range-based for loop modifies the contents of a container, and the trick is to develop a reference parameter. For example, suppose you have the following function:voi

Nested use of volist 1. An important feature is that if the volist name corresponds to an array, it will traverse the array.For example XxxWhile $ Comments [0] = $ comment1;$ Comments [1] = $ comment2;Then the above Code will first treat $ comment1 as vo and execute the code XXX again;Then, use $ comment2 as vo and execute XXX again.So when you draw a comment box, as long as the above code, it will automatically draw all the comment boxes. 2. If nested, use the following method to obtain the n
