 The Python API in gprMax allows users to access to gprMax functions directly from Python through importing the gprMax module. There are several advantages to using the API: 
 
-1. Users can take advantage of the Python language - for instance, the structural elements of Python can be utilised more easily.

-2. gprMax objects can be used directly within functions, classes, modules and packages. In this way collections of components can be defined, reused and modified. For example, complex targets can be imported from a separate module and combined with an antenna from another module.

 The syntax of the API is generally more verbose than the input file (hash) command syntax. However, for input file commands where there are an undefined number of parameters, such as adding dispersive properties, the user may find the API more manageable.
