python - How can I call a function defined in another function? -


Today I came to know that I can not find a way to call the function within any other function. Unless I explicitly return it to the main function or use the closure structure. But I am thinking that there is another way to call him. Or it will not be so wired, Python allows me to define functions inside the function, but I do not allow them to use them in a simple way!

My code is such, and I 

  def a (): def b (): print 'b' def c (): calling 'print' c For example, call b (), c (), d (). 'Def D (): Print' D 'print' A '& gt; & Gt; & Gt; One () A & gt; & Gt; & Gt; AB Properties: There is no attribute in 'Function' object 'B' & gt; & Gt; & Gt; Eb () attribute: 'object' does not have any attribute 'b'    
 
 
 Can not call those functions from outside the scope of the  a  they are limited to the scope of  a   
 You can think of these tasks in the same way As you think about other local names in the function. For example: def foo (): bar = 42   
 As soon as you can not reference your local tasks outside the defined radius, you can not mention it  bar   foo () . Outside the scope of

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
