In each case, you can use Python lists. For instance, the third case
would be:
coupons = [ 0.0200, 0.0225, 0.0250, 0.0275, 0.0300,
0.0325, 0.0350, 0.0375, 0.0400, 0.0425,
0.0450, 0.0475, 0.0500, 0.0525, 0.055 ]
In the first two cases, you don't need separate initialization. You can
create the list using list comprehension; for example, 1) would be:
quote = [ SimpleQuote(cleanPrice[i]) for i in range(len(cleanPrice)) ]
or better yet
quote = [ SimpleQuote(p) for p in cleanPrice ]
In general:
- shared_ptr is hidden in the SWIG interfaces, so you can just omit it
and use the pointed class directly;
- for vectors, use Python lists.
