QUESTION
What I have now: (problem at bottom of page)
...ANSWER
Answered 2021-Jun-14 at 03:08You can't exactly get input to a file but you can get the input from the user and insert it into a file. You open a file as open("filename.txt,"r")
to read or "w"
to write or "r+"
for both.

Answered 2021-Jun-11 at 18:44Your groupBy/agg
is on the right track except that filter("job")
makes no sense in agg()
. Use pivot

QUESTION
Problem: I'm having difficulty finding a way to identify which of two TableLayout objects are being passed to a method.
What I'm trying to do: I'm trying to use Singleton class with list of Static methods that perform common setup functions when creating and or editing a TableLayout
programmatic-ally.
For example, since creating an 'add' Button
within a TableRow
for each TableLayout
is identical except for the button OnClickListener
action, I would like to simply pass the TableLayout object. I then use the TableLayout variable name of that object to identify the correct OnClickListener setup.
In the code example below, the if - else
is an example of what I would like to do. I know there isn't a method name()
... it is my way of demonstrating in the code what I would like to do.
ANSWER
Answered 2021-Jun-04 at 18:49You can use the setTag
method, which allows you to set an arbitrary object to a view. For example:
QUESTION
I've been working with Isabelle/HOL for a few months now, but I've been unable to figure out the exact intention of the use of _tac.
Specifically, I'm talking about cases vs case_tac and induct vs indut_tac (although it would be nice to know the meaning of tac in general, since I'm also using other methods such as cut_tac).
I've noticed I can't use cases or induct using apply with ⋀-bound variables, but I can if it's an structured proof. Why?
An example of this:
...ANSWER
Answered 2021-Jun-06 at 01:13*_tac
are built-in tactics used in apply
-scripts. In particular, case_tac
and induct_tac
have been basically superseded by the cases
and induction
proof methods in Isabelle/Isar. As you mentioned, case_tac
and induct_tac
can handle ⋀-bound variables. However, this is quite fragile, since their names are often generated automatically and may change when Isabelle changes (of course, you could use rename_tac
to choose fixed names). That's one of the reasons why nowadays structured proof methods are preferred to unstructured tactic scripts. Now, back to your example: In order to be able to use cases
, you can introduce a structured block as follows:
QUESTION
Apologies for asking a fairly common question, I have been looking all over and can't find a solution that fixes my problem.
I am using Firesharp, and trying to deserialize a Json object that Firebase returns into a class with a nested list.
...ANSWER
Answered 2021-May-26 at 14:30This in no way a complete answer. I assume you don't want to map/create classes for each "sub class", e.g. Barbarian, Wizard etc. You could perhaps use JsonConverter. The example only handles the first "anonymous" range of objects. Maybe you'll find some of this useful.
QUESTION
I would like to implement CTRL + Drag & Drop
in FullCalendar v5 using PURE JavaScript only.
UPDATE
This solution works ONLY when pressing CTRL key BEFORE dragging. Guerric P's answer works only when the CTRL key is press after dragging the event. I would like to have solution when it does not matter when the CTRL key is pressed.
UPDATE ends
I did my reseach on topic and found that this was discussed as a new feature UI request on FC github. There are few suggestions how to do that, even working ones.
...ANSWER
Answered 2021-May-25 at 12:11I have a minimal solution that works. It consists in cloning the moved event at its original date if the Ctrl key is being held.
To test this snippet, just click into the input at the top of the page before testing, otherwise the result iframe
doesn't have the focus and doesn't fire keydown
and keyup
events.
QUESTION
I am looking to transpose a table dynamically to be populated column-wise, rather than row-wise. My table headers must go column-wise first, and my subsequent data must populate it in that orientation.
I have created an example for simplicity.
My current table is as follows:
however, I would like it to look like:
...ANSWER
Answered 2021-May-25 at 01:51For a generic transpose, you could do something like:

if float(value) > float(largest):
largest = value
...ANSWER
Answered 2021-May-19 at 04:35Considering that largest
contains the largest value, you can find the key associated with it by iterating over the dictionary (key, value)
