Mastering Python for Finance

Summary

In this chapter, we looked at the use of the Component Object Model (COM) to allow the reuse of objects across different software and hardware environments to interface with each other, without the knowledge of its internal implementation.

To build the server component of the COM interface, we used the pythoncom module to create a Black-Scholes pricing COM server with the three magic variables: _public_methods_, _reg_progid_, and _reg_clsid_. Using topics in Chapter 4, Numerical Procedures, we created COM server components using the binomial tree by the CRR model and trinomial lattice model. We learned how to register and unregister these COM server components with the Windows registry.

In Microsoft Excel, we can input a number of parameters ...
