python - Output gets erased in a recursive function -


i have created recursive function in python down below calculates power reached node other , finding based on radius of coverage of nodes.

what want take output function , call recursive function on 1 more time without losing output got , don't know how that.

this function below:

def find_new_int(node_in_ex, old_inters):     global power_sensitivity     global copy_of_int_list     intersection_list_method = []     wall_coordinates in lines:         if intersection_rand_point(wall_coordinates[0], wall_coordinates[1], node_in_ex-1, old_inters) not false:             intersection_list_method.append(intersection_rand_point(wall_coordinates[0], wall_coordinates[1], node_in_ex-1, old_inters))     intersection_list_method = sorted(list(itertools.chain(*intersection_list_method)), key=cal_distance_av)     points in intersection_list_method:         if cal_pow_rec_plndwall(node_in_ex, points) > power_sensitivity:             return intersection_list_method     points in intersection_list_method:         return find_new_int(node_in_ex, points)

i want loop on intersection_list_method outputed first time ran function >>if<< function didn't return intersection_list_method in 3rd line bottom. problem im doing here when call 

find_new_int(node_in_ex, points)

again intersection_list_method looping on gets erased , new 1 created want loop on each point in list instead , see if function return list every point in intersection_list_method till ends

any help?

your code this:

for points in intersection_list_method:     return find_new_int(node_in_ex, points)

but want is:

but if didn't find point power > power sensitivity in list want again call same function on each point in list again till returns something.

assuming opposite of "returns something" "returns none", this:

for points in intersection_list_method:     result = find_new_int(node_in_ex, points)     if result not none:         return result

i have code gives message when key number pressed: txtvalueofclause.addeventfilter(keyevent.key_typed, new eventhandler<keyevent>() { @override public void handle(keyevent t) { char ar[] = t.getcharacter().tochararray(); char ch = ar[t.getcharacter().tochararray().length - 1]; if (!(ch >= '0' && ch <= '9')) { system.out.println("the char entered not number"); t.consume(); } } }); now if press on wrong button , press backspace remove it, error message. how can add backspace input if statement? i have found answer: txtvalueofclause.addeventfilter(keyevent.key_typed, new eventhandler<keyevent>() { @override public void handle(keyevent t) { char ar[] = t.getcharacter().tochararray(); char ch = ar[t.getcharacter().tochar
