notready = [i for i in np3 if i not in np4]
print(f"not ready: {notready}")
The purpose is to use string format keyword in keyword list to examine its existence in all np2 elements.
If any element in np2 starts with any keyword, or keyword is the substring of any element in np2, get the index of element in expectation which also start with that keyword and form into np4.
Finally， get not ready which is made up of elements that are in np3 but not in np4.
To make my explanation more vividly, I have a bunch of rpm files to be installed, the list of expectation.
The keyword list catches the former two keywords of each rpm file name.
Result is the standard output of already installed rpm files.
Taking cpp-4.8.5 as an example, I can see cpp-4.8.5-44.el7.x86_64 in result, which means currently cpp-4.8.5-44.el7.x86_64 has been installed. So, cpp-4.8.5-39.el7.x86_64 in expectation can be removed, since cpp-4.8.5-*.rpm has been successfully installed. Next step, deal with the other left items in expectation.
My question is: there any easier or more efficient way to get the result equivalent to notready? maybe with any other numpy built-in methods, but not with for loop.
