1. ModuleWhen writing the module, try not to have the same name as the module that comes with the system.When the module is called, it is looked up in the current directory for the module, and then it looks like a python environment variable.A. Module 1:sysThe code is as follows:1 Import sys2 print (Sys.path) The purpose of this code is to print out the Python environment variables as follows:D:\\python Training \\s14\\day2D:\\python Training \\s14D

We can see that S0 (5.00) = S1 (2.00) + S2 (3.00 ).The second case is to add a group of vectors and a scalar (fadds S8, S24, S0). The result is:S8 (26.00) = S24 (25.00) + S0 (1.00)S10 (28.00) = s26 (27.00) + S0 (1.00)S12 (30.00) = s28 (29.00) + S0 (1.00)S14 (32.00) = S30
