python - Work with tuple of dictionaries -
i have following tuple of dictionaries:
td=({'associatedframe': none, 'cyclicmodenumber': none, 'description': 'increment 10: arc length = 7.2813e-02', 'domain': 'arc_length', 'fieldoutputs': 'repository object', 'frameid': 10, 'framevalue': 0.0728124976158142, 'frequency': none, 'incrementnumber': 10, 'isimaginary': false, 'loadcase': none, 'mode': none}) i'd value associated key frameid. don't have many experience tuples , dictionaries , questions i've found dictionaries of tuples, ask help. thanks
edit: had tried solution forgot mention i'm using python results program. program has specific organisation in order work had write td.frameid.
if have, dictionary.
td['frameid'] will work. parenthesis don't make tuple. comma makes tuple.
foo = (1) #integer foo = (1,) #1 element tuple foo = 1, #1 element tuple parenthesis necessary in few situations syntax otherwise ambiguous (like function calls). clearly:
foo(1,2,3) is different than;
foo(1,(2,3)) if have tuple, need index dictionary can index item want.
td[0]['frameid']
