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

(also, worth noting, that it's a bit annoying that you re-posted your question out of the original thread. Now I have two George-asks-about-PMT threads with identical content. Please don't re-post questions that you've asked not 24hrs ago; that's a bit of a waste of everyone's time.)

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.



Best regards,
Marcus

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.

Hello GNURadio Community,

Let's assume the following pmt definitions for a list and and dictionary in an 
OOT block:
P_list = pmt.to_pmt([1, 2, 3.45, 'eggs'])
P_dict = pmt.to_pmt({'spam': 20, 'eggs': 40})



Thank you!

George

How do I explicitly extract the first element in P_list and the value for 'spam' from P_dict?
