I think you mean to use map instead of filter: Even simpler, you could use str.upper instead of importing from string (thanks to @alecxe): In Python 2.x, map constructs a new list by applying a given function to every element in a list. filter constructs a new list by restricting to elements that evaluate to True with a given function. In Python 3.x, map and filter construct iterators instead of lists, so … Read more
In the header you have: Which takes 5 arguments, In the source file you have: which takes 6 arguments. It seems like int numCheck does not match the header signature.
The problem, as the Traceback says, comes from the line x[i+1] = x[i] + ( t[i+1] – t[i] ) * f( x[i], t[i] ). Let’s replace it in its context: x is an array equal to [x0 * n], so its length is 1 you’re iterating from 0 to n-2 (n doesn’t matter here), and i … Read more
You could simply use which does exactly the same as Your function will also return None if execution reaches the end of the function body without hitting a return statement. Returning nothing is the same as returning None in Python.
This would be my approach:
When creating the TABLE under B2BOWNER, be sure to prefix the PL/SQL function with the Schema name; i.e. B2BOWNER.F_SSC_Page_Map_Insert. I did not realize this until the DBAs pointed it out. I could have created the table under my root USER/SCHEMA and the PL/SQL function would have worked fine.
You must make Foo::comparator static or wrap it in a std::mem_fun class object. This is because lower_bounds() expects the comparer to be a class of object that has a call operator, like a function pointer or a functor object. Also, if you are using C++11 or later, you can also do as dwcanillas suggests and use a lambda function. C++11 also has std::bind too. Examples:
Let us have two files in the same directory. Files are called main.py and another.py. First write a method in another.py: Then call the method from main.py. Here is the main.py: Run main.py and you will get output like this: N.B.: The above code is being executed using Python 2.7 in Windows 10.
There isn’t any need to add file.py while importing. Just write from file import function, and then call the function using function(a, b). The reason why this may not work, is because file is one of Python’s core modules, so I suggest you change the name of your file. Note that if you’re trying to import functions from a.py to a file called b.py, … Read more
In my index.php I’m loading maybe foobarfunc() like this: but can also be You can not invoke method this way because it is not static method. You should instead use: If however you have created a static method something like: then you can use this:
