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

In Python programming, the most common types of collections we use are: list,tuple,set,dict; let's talk about these types of collections in a few simple ways;List lists: Equivalent to an array, but the length of the list is automatically changed and the elements are free, without having to be the same type for each ele
