% 
% Welcome! This EMT notebook demo uses my python script psql.py, which
% is inspired from chapter 3 of Bernt Arne Odegaard's book "Financial
% Numercial Recipes in  C++" April 2007 edition We will first call the
% underlying codes by import command
% 
% In this EMT notebook, we are calling python 3.8 commands Please check
% official website of EMT to know "How to call python 3.8 in EMT"
% 
>>> import psql
% 
% We can define data list for using them as function paramters
>>> CF = [-100, 75, 75]  
>>> time = [0, 1, 2]
>>> r4discount = 0.10
% 
% Now we are ready to call functions from psql script
% 
>// Example 1 : One interest with discrete discounting
>>> : psql.pv_discrete(CF,time,r4discount) 
30.165289256198328
% 
>// Example 2 : One interest with continous discounting
>>> : psql.pv_continous(CF,time,r4discount)
29.2676128335456
% 
>// Example 3 : Finding Internal rate of returns using discrete discounting 
>>> time = [0,1,2]
>>> CF = [-100,10,110]
>>> NPV = psql.pv_discrete(CF,time,0.05)
>>> r= psql.irr(CF,time)
>>> print("Present value, 5% discretely discounted interest = ", NPV ,"\n and Internal rate of return, discrete discounting = ", r )
Present value, 5% discretely discounted interest =  9.297052154195 
 and Internal rate of return, discrete discounting =  0.1
