keyword

I have a list of words in a dictionary with the value = the repetition of the keyword but I only want a list of distinct words so I wanted to count the number of keywords. Is there a way to count the number of keywords or is there another way I should look for distinct words? len(yourdict.keys()) or just len(yourdict) If you like to count unique words in the file, you could just use set and do like len(set(open(yourdictfile).read().split())) The number of distinct words (i.e. count of entries in the dictionary) can be found using the len() function. > a = {'foo':42, 'bar':69} > len(a) 2 To get

Has anyone ever actually used stackalloc while programming in C#? I am aware of what is does, but the only time it shows up in my code is by accident, because Intellisense suggests it when I start typing static , for example. Although it is not related to the usage scenarios of stackalloc , I actually do a considerable amount of legacy interop in my apps, so every now and then I could resort to using unsafe code. But nevertheless I usually find ways to avoid unsafe completely. And since stack size for a single thread in .Net is ~1Mb (correct me if I'm wrong), I am even more reserved from using

I am new to Haskell and I am very confused by Where vs. Let . They both seem to provide a similar purpose. I have read a few comparisons between Where vs. Let but I am having trouble discerning when to use each. Could someone please provide some context or perhaps a few examples that demonstrate when to use one over the other? Where vs. Let A where clause can only be defined at the level of a function definition. Usually, that is identical to the scope of let definition. The only difference is when guards are being used . The scope of the where clause extends over all guards. In contrast, the

I am trying to use the PL/R procedural language in a PostgreSQL 9.2 database. I have installed the plr language and I am trying to add it to a database. When I run the command CREATE EXTENSION plr; I get the following error: ERROR: language "C" does not exist STATEMENT: CREATE EXTENSION plr; ERROR: language "C" does not exist When I list the available languages in the database with select * from pg_language; I get lanname | lanowner | lanispl | lanpltrusted | lanplcallfoid | laninline | lanvalidator | lanacl ----------+----------+---------+--------------+---------------+-----------+-----------

I'm confused about this. Most of us have been told that there isn't any goto statement in Java. But I found that it is one of the keywords in Java. Where can it be used? If it can not be used, then why was it included in Java as a keyword? The Java keyword list specifies the goto keyword, but it is marked as "not used". It was in the original JVM (see answer by @VitaliiFedorenko ), but then removed. It was probably kept as a reserved keyword in case it were to be added to a later version of Java. If goto was not on the list, and it gets added to the language later on, existing code that used

This question already has an answer here: Why does Java have transient fields? 13 answers I have an issue related to the transient keyword's use before the private modifier in java . variable declaration: transient private ResourceBundle pageResourceBundle; My class looks like this : public class LoginViewModel extends AbstractViewModel { transient private ResourceBundle pageResourceBundle; @AfterCompose public void afterCompose(@ContextParam(ContextType.VIEW) Component view) { initializeLoginValues(); boolean timeout = BooleanUtils.toBoolean(getHttpServletRequest().getParameter("timeout"));
