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

') and a protocol (such as 'tcp 'or 'udp '), return the port number used by the service: >>> Socket. getservbyname ('http ', 'tcp ') 80 >>> Socket. getservbyname ('telnet ', 'tcp) 23 Generally, non-Python programs store and use IP addresses in a 32-bit byte package. The inet_aton (ip_addr) and inet_ntoa (packed) functions are Converted to IP addresses in this form: >>> Socket. inet_aton ('2017. 76.216.16 ') '\ XdeL \ xd8 \ x10' >>> Socket. inet_nto

Implement Hill sorting by python programming and python Hill sorting Observe "insert sort": in fact, it is not difficult to find that she has a disadvantage: If the data is "5, 4, 3, 2, 1", we insert the records in the "unordered block" into the "ordered block", it is estimated that the records will crash, each insert operation must move its position. The efficie

I translated from "Exper Python Programming"' Premature optimization is the root of all evil in programming '-donald KnuthThree Principles of optimization Let it run, first. One of the most common mistakes is that we begin to optimize the code at the beginning of the code. The sad thing is that this is usually done useless work, a lot of software on

Initial knowledge of socket programmingFirst, prefaceThe socket is based on the programming model of the C\S architecture (client \ Server), which is present in Python as a socket module.A socket is an intermediate software abstraction layer that the application layer communicates with the TCP/IP protocol family, which is a set of interfaces. In design mode, thesocket is actually a façade mode, it is the co

There is no independent function in C #, only the concept of a class (dynamic or Static) method, which refers to a member of a class that performs calculations or other behavior. In Python, you can define a dynamic or static member method of a class in a way similar to C #, because it supports full object-oriented programming as it does in C #. You can also write Python
