keyword

One use of the var keyword in C# is implicit type declaration. What is the Java equivalent syntax for var ? Mike Caron There is none. Alas, you have to type out the full type name. Edit: 7 years after being posted, type inference for local variables (with var ) was added in Java 10. Edit: 6 years after being posted, to collect some of the comments from below: The reason C# has the var keyword is because it's possible to have Types that have no name in .NET. Eg: var myData = new { a = 1, b = "2" }; In this case, it would be impossible to give a proper type to myData . 6 years ago, this was

How do I data mine a pile of text to get keywords by usage? ("Jacob Smith" or "fence") And is there a software to do this already? even semi-automatically, and if it can filter out simple words like "the", "and", "or", then I could get to the topics quicker. The general algorithm is going to go like this: - Obtain Text - Strip punctuation, special characters, etc. - Strip "simple" words - Split on Spaces - Loop Over Split Text - Add word to Array/HashTable/Etc if it doesn't exist; if it does, increment counter for that word The end result is a frequency count of all words in the text. You can

In a Python script I call a function from rpy2 , but I get this error: #using an R module res = DirichletReg.ddirichlet(np.asarray(my_values),alphas, log=False, sum.up=False) SyntaxError: keyword can't be an expression What exactly went wrong here? sum.up is not a valid keyword argument name. Keyword arguments must be valid identifiers. You should look in the documentation of the library you are using how this argument really is called – maybe sum_up ? I guess many of us who came to this page have a problem with Scikit Learn, one way to solve it is to create a dictionary with parameters and

In Python 2, we could reassign True and False (but not None ), but all three ( True , False , and None ) were considered builtin variables. However, in Py3k all three were changed into keywords as per the docs . From my own speculation, I could only guess that it was to prevent shenanigans like this which derive from the old True, False = False, True prank. However, in Python 2.7.5, and perhaps before, statements such as None = 3 which reassigned None raised SyntaxError: cannot assign to None . Semantically, I don't believe True , False , and None are keywords, since they are at last

I've seen in several code examples, they use the static keyword in front of variables and in front of functions. What is the purpose in case of using with a variable? And what is the purpose in case of using with a function? Roux hass Just as a brief answer, there are two usages for the static keyword when defining variables: 1- Variables defined in the file scope with static keyword, i.e. defined outside functions will be visible only within that file.
