nested

I've been trying to figure this out all evening but to no avail. I have a JSON structure as follows (coming from another system so I can't change its structure): { "parents":{ "parent":[ { "parentId":1, "children":{ "child":[ { "childId":1, }, { "childId":2, } ] } }, { "parentId":2, "children":{ "child":[ { "childId":1, }, { "childId":2, } ] } } ], "pageNum":1, "pageSize":2 } } However, I can't figure out what the correct structure for the data models should be. I've tried the following but it does not work. BTW, I can access the parent information. The issue is with accessing the child

I'm trying to create a generic function that replaces dots in keys of a nested dictionary. I have a non-generic function that goes 3 levels deep, but there must be a way to do this generic. Any help is appreciated! My code so far: output = {'key1': {'key2': 'value2', 'key3': {'key4 with a .': 'value4', 'key5 with a .': 'value5'}}} def print_dict(d): new = {} for key,value in d.items(): new[key.replace(".", "-")] = {} if isinstance(value, dict): for key2, value2 in value.items(): new[key][key2] = {} if isinstance(value2, dict): for key3, value3 in value2.items(): new[key][key2][key3.replace("."

Why this query doesn't work? :( I tried to replace nested IF statement "...SET lkey = IF(lkey >= 11, lkey - 5, IF(lkey > 5, lkey + 2,lkey))" UPDATE pages SET lkey = CASE lkey WHEN lkey >= 11 THEN lkey - 5 ELSE CASE lkey WHEN lkey > 5 THEN lkey + 2 ELSE lkey END END, rkey = CASE lkey WHEN lkey >= 11 THEN rkey - 5 ELSE CASE rkey WHEN rkey < 11 THEN rkey + 2 ELSE rkey END END WHERE rkey > 5 AND lkey < 12; The syntax is wrong in this clause (and similar ones) CASE lkey WHEN lkey > 5 THEN lkey + 2 ELSE lkey END It's either CASE WHEN [condition] THEN [expression] ELSE [expression] END or CASE

I have a big problem with my UIPageViewController . I want to present content in my app using sections and sub-sections. So, I have created "two" instances of UIPageViewController - horizontal (red) and vertical (blue): Earlier I said I have created "two" instances - it is not quite true - there can be tens of instances, but only 2 are presented at the same time, you know what I mean . Both controllers have transitionStyle set to UIPageViewControllerTransitionStyleScroll . The red UIPageViewController is responsible for horizontal scrolling between sections and blue are responsible for

My problem According to the Google's docs: You can now embed fragments inside fragments. This is useful for a variety of situations in which you want to place dynamic and re-usable UI components into a UI component that is itself dynamic and re-usable. For example, if you use ViewPager to create fragments that swipe left and right and consume a majority of the screen space, you can now insert fragments into each fragment page. To nest a fragment, simply call getChildFragmentManager() on the Fragment in which you want to add a fragment. This returns a FragmentManager that you can use like you

This is related to a chapter from beautiful code . And in that chapter I read about the nested if s. The author was talking about deeply nested if s as originator of bugs and less readable. And he was talking about replacing nested if s with case statements and decision tables . Can anybody illustrate how to remove nested if s with case ( select case ) and decision tables ? Lasse Vågsæther Karlsen Well, not directly an answer to your question since you specifically ask about switch/case statements, but here is a similar question. Invert “if” statement to reduce nesting This talks about
