反应式编程将结果存储在变量中

Question

quick (trivial) question: I cannot find a way to store the output of a series of operation on an observable in an external variable. For instance something like that:

mylist = []
Observable.from_([1, 2, 3]).to_list().store(mylist)

Not sure this is very "reactive", but should be trivial.

Thanks in advance

Answer 1

Here is a solution i found:

mylist = []

def store(value):
    mylist.append(value)

Observable.from_([1, 2, 3]).do_action(store).subscribe()

print(mylist)

Comments?

Thanks

Turn your observable into a blocking one via .to_blocking() . Now you can iterate over it.

mylist=list(Observable.from_([1, 2, 3]).to_blocking())                                                                   

print(mylist)
