First, we'll want to split the input (192.168.1.1/24) into the CIDR and the IP address for individual processing. addrString,cidrString = sys.argv[1].split('/') The string split method always returns a list. In this case, our list will have two values: the IP address (which we ...
The following two examples show how to use the split function to break a string into a list of the substrings that make up the original string. (The list is another built-in data type in Python that we’ll discuss later in this chapter.) The split function can take up to two addition...
Installation: Install all the required pre-requisites libraries (see Appendix I for a complete list). Input loading: Load the input data in the input//case_study folder. Make sure that the dependent variable is in the last column of your csv file. In particular, the protocol communicates wit...
