The Python programming language already has many followers. Why? Many people cannot understand this problem. Next, let's look at the reason why the Python programming language is so phantom. I hope you will have some gains.
Despite this, most Internet projects still need to be built by the Perl "hero. But there is no c

SocketSockets are also commonly referred to as "sockets," which describe IP addresses and ports, and are a handle to a chain of communication, where applications usually make requests to the network through "sockets" or respond to network requests.Sockets originate from UNIX, and one of the basic philosophies of unix/linux is "Everything is file", and the file is operated with "open" "Read and Write" "Off" mode. Socket is an implementation of this pattern, the socket is a special kind of file, s

Other arithmetic operations are performed before the boolean operator
Python supports comparisons such as:aint = 50 while Booleanexpression:#suite 1#else:#suite2When the while loop Boolean expression is false, the Else statement is entered. Note: A while inside of a break out of the loop also skips the Else statement.

When we are programming, some of the code is fixed, such as socket connection code, read the file contents of the code, generally I will search the Internet and then directly paste down to change, of course, if you can remember all the code that more powerful, but their own writing is not as fast as pasting, and write their own code to test, and a test of the code can be used many times, so here I summed up a few of the common
From C # To Python -- 3 function and function programming,
In C #, there is no independent function. Only the class (dynamic or static) method is used. It refers to the member used to execute computing or other behaviors in the class. In Python, you can use a method similar to C # To define the dynamic or static member methods of a class, because it supports full
