As a purely academic exercise, I set out on finding a simple solution to a problem that had been bugging me for some days:
The traverser has to go through each and every key pair value and print the value assigned.
So I came up with this semi-recursive solution. I don’t feel it is elegant enough, although this is the best I could do for now. I am looking into better ways for a proper tree search which JSON traversal is all about.
def traverse_dict(json_data): for value in json_data.itervalues(): if isinstance(value, dict): traverse_dict(value) elif isinstance(value, list): traverse_list(value) else: print_element(value) def traverse_list(data_list): for item in data_list: if isinstance(item, dict): traverse_dict(item) elif isinstance(item, list): traverse_list(item) else: print_element(item) def print_element(element): print "Traversing: " + str(element)
