Here is how you would do this with a nested list comprehension: [[float(y) for y in x] for x in l] This would give you a list of lists, similar to what you started with except with floats instead of strings. If you want one flat list then you would use [float(y) for x in … Read more
The HTML5 spec tells us that the <p> element’s content model is phrasing content. Phrasing content is defined by the spec: 3.2.5.1.5 Phrasing content Phrasing content is the text of the document, as well as elements that mark up that text at the intra-paragraph level. Runs of phrasing content form paragraphs. a (if it contains … Read more
This can be done with a clever combinartion of _.map and _.groupBy. const items = [ { tab: ‘Results’, section: ‘2017’, title: ‘Full year Results’, description: ‘Something here’, }, { tab: ‘Results’, section: ‘2017’, title: ‘Half year Results’, description: ‘Something here’, }, { tab: ‘Reports’, section: ‘Marketing’, title: ‘First Report’, description: ‘Something here’, } ]; … Read more
You can safely use multiple forms in a JSF page. It’s not different than when using plain HTML. Nesting <form> elements is invalid in HTML. Since JSF just generates a bunch of HTML, it’s not different in JSF. Nesting <h:form> is therefore also invalid in JSF. <h:form> … <h:form> <!– This is INVALID! –> … … Read more
Found an alternative at Child elements with margins within DIVs You can also add: .parent { overflow: auto; } or: .parent { overflow: hidden; } This prevents the margins to collapse. Border and padding do the same. Hence, you can also use the following to prevent a top-margin collapse: .parent { padding-top: 1px; margin-top: -1px; … Read more
No. It’s that easy. A finite automaton (which is the data structure underlying a regular expression) does not have memory apart from the state it’s in, and if you have arbitrarily deep nesting, you need an arbitrarily large automaton, which collides with the notion of a finite automaton. You can match nested/paired elements up to … Read more
Test for existence of nested JavaScript object key
As you are dealing with dict, you can leverage the items() method to loop through it. Here is an explicit code on how to do so: patients_dict = {“Anna”: {‘age’:16, ‘height’:165, ‘weight’:65}, “Barbara” : {‘age’:100, ‘height’:120, ‘weight’:40}, “Carlo” : {‘age’:36, ‘height’:150, ‘weight’:60}, “Dende” : {‘age’:27, ‘height’:183, ‘weight’:83}} tall_patients = [] for patient, infos in patients_dict.items(): … Read more
You just need to see the pattern and replicate it in your code. Here is one way to solve this, which can also be used to produce larger matricies (set the max variable to a different value): public class main{ public static void main(String[] args){ int max = 5; for(int i = 1; i < … Read more
You could just use zip like, >>> list1 [[1, 2, 3], [4, 5, 6]] >>> list2 [[10, 2, 3], [11, 5, 6]] >>> [[x+y for x,y in zip(l1, l2)] for l1,l2 in zip(list1,list2)] [[11, 4, 6], [15, 10, 12]] or if you are not sure, if both list will be of same length, then you … Read more
