In the HelloWorld project, a simple two-sum program was written, how to use Python to invoke it after compiling it into a shared library? Use the LL command to list the shared libraries under the current directory, where the shared library name is libhelloworld.so.0.0.0 Copy Code code as follows: ufo@ufo:~/helloworld/.libs$ LL Total Dosage 32
