Re: How do I extract individual values from pmt list and dict

[Marcus Müller]

Hi George,

first_element = pmt.vector_ref(P_list, 0)

and

spam_element = pmt.dict_ref(P_dict, pmt.to_pmt('spam'), pmt.PMT_NIL)

respectively.

Note that you must not put "payload" data into strings that you put into PMT. 
`pmt.to_pmt(str)` generates a PMT symbol, and these are saved for evermore in a global table.

Best regards,
Marcus
