if statement - if variable is assigned then check some condition in python -


I'm coding in Python My problem is that I have a variable strGUID in the function And then if there is a control flow in which I want to see that the variable is specified and if yes, then check it on some condition. The clear sample of code is as follows: for the row in the list : if line.find ('project')! = - 1 strGUID = line.split (',') [2]. Strip ('' ') if flags == wrong and line Address (strGUID) == - 1: print 'written line:', line

I get an error in the code given above

Say this The variable SRRDAD is reaching before its assignment.

is defined and if it then checks the position: line.find (strGUID) == - 1 . Such a thing 

  if flag == incorrect and (if strGUID again line.find (strGUID) == - 1):   
 PS: this is just code To minimize and make it intelligent, I know that if I can write longer in check, the code is, therefore the purpose of asking for it is not objective. Explanation: If you want to suggest the answer, where you have provided strig = nobody and then check it in another IUP loop, I want to execute. Print is printed even when no one That is why I am searching for a wise way to define if the condition. That is, I want to execute the print if struda = none or if there is no struda and the row Address (strGUID) == - 1  
 Edit: Basically my current code is the second in the form of a loop:  
  if flag == incorrect and (struda No one is there (or struda no and line. Address (strGUID) == - 1)):   
 I want to test whether it is an intelligent way of shortening it is.  
  
 
 
 The customary way to do this would be to initially set  strGUID = none  And then check  
  if flag == incorrect and (struda none and line.field (strGUID) == -1):   
 if The first part ( none of the synthesis ) is incorrect, the second part ( line.find (strGUID) == -1 ) will never be evaluated.

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...
