One day, using Centos7, when discovering the network configuration, the subnet mask needs to be converted manually, because the CENTOS7 network is configured as follows:NMCLI Connection Enp4s0 Modify Ipv4.methord manual ipv4.address "192.168.1.120/24" Ipv4.gateway "192.168.1.1" Ipv4.dns "2 23.5.5.5 "A configuration item with no subnet mask. Then, write a function that implements the mutual transformation of the subnet mask and the bit length.One: The subnet mask is converted to bit length:# Codi

ASCII is a character set, including uppercase and lowercase letters, numbers, control characters, and so on, which is represented in a single byte, and the range is 0-127 Unicode is divided into UTF-8 and UTF-16.UTF-8 variable length, up to 6 bytes, characters less than 127 are expressed in one byte, and as with the ASCII character set, the English text under ASCII encoding does not need to be modified to be processed as UTF-8 encoding.Python supports Unicode starting from 2.2, and function deco

Recently, a third-party called API has been developed for a self-developed software platform. If the returned result set is in JSON format, it is easier to develop it in other languages, I found a lot of information on the Internet and didn't find it very suitable. Finally, I decided to change my mind to write a general one based on the information on the Internet. The main application scenario of this method is to convert the query results of the
