Python Recursion Handling -


i have recursively traverse objects inside list.

def function():    object in list:       if object.field none:          // stuff here       else:            function(object.field)    return

the problem i'm facing python doesn't object inside list, instead return every time meet " object.field != none " . want return when loop over, until object inside list done.

can explain me way this?

you're calling function again when object.field none. first block of if run when object.field != none. else run when object.field == none.
