python - list reverse, list multiple by -1 -

-

अपेक्षित परिणाम: 

  & gt; & gt; & gt; (5, 4, 3, 2, 1], [-5, -4, -3, -2, -1], [-1, -2, -3, -4, -5])   
 मेरा कोड:  
  # फ़ंक्शन लिखें जो एक पोस्टिव नंबर के अनुसार 4 सूचियों को देता है। Def createLists (num): ls = [आइटम में श्रेणी (num)] वापसी सेट (ls, ls.reverse (), ls.reverse () * (- 1), ls * (- 1))   
 कोई भी मुझे मार्गदर्शन करता है कि यह कैसे करें?   
 
 
  def सेट सूची (Num): ls = range (1, num + 1) रिटर्न (ls, ls [:: - 1], [-n के लिए n में ls] [:: - 1], [-n के लिए n में ls]) प्रिंट बनावट सूची (5)

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
