unit testing - What's the difference between assertEqual and assertIs (assertIs was introduced in Python 2.7)? -

-

संदर्भ - 

  assertEqual (a, b) # जांचता है कि a == b assertIs (ए, बी) # जांचता है कि ए है बी एंड एलटी; ---- जो भी इसका मतलब है ???    
 
 
  assertEqual  का उपयोग करना दो वस्तुओं की आवश्यकता नहीं है एक ही प्रकार, वे केवल एक ही मूल्य की आवश्यकता है। तुलना में,  assertIs  का उपयोग करके दो वस्तुओं को एक ही ऑब्जेक्ट की आवश्यकता होती है।  
  assertEqual  समानता के लिए  ==  परीक्षण ऑपरेटर:  
 
 ऑपरेटर & lt ;, & gt ;, ==, & gt; =, & lt; =, और! = दो वस्तुओं के मूल्यों की तुलना करें वस्तुओं को एक ही प्रकार की आवश्यकता नहीं है। यदि दोनों संख्याएं हैं, तो उन्हें एक सामान्य प्रकार में बदल दिया जाता है। अन्यथा, विभिन्न प्रकार के ऑब्जेक्ट हमेशा असमान की तुलना करते हैं, और इन्हें लगातार, लेकिन स्वैच्छिक रूप से आदेश दिए जाते हैं।   
  assertIs  ऑब्जेक्ट आइडेंट के लिए परीक्षा, जैसा कि  है  और  नहीं है  ऑपरेटर्स:  
 
 ऑपरेटर ऑब्जेक्ट आइडेंटिटी के लिए है और परीक्षा नहीं है: एक्स है y सत्य है अगर और केवल अगर एक्स और वाई समान ऑब्जेक्ट हैं X नहीं है, व्युत्क्रम सत्य मान पैदा करता है।   
 उपरोक्त उद्धरण दोनों पायथन दस्तावेज़ अनुभाग से आते हैं।

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.

Gatefolder path (environment specialfolder personal), "mydb.db3"); // The following line will be called coolestation, where is the database, // to make it if it does not exist, and call a delegate that creates the necessary tables (only when the database file was newly created //) CSConfig.SetDB (DbName, true, () => {CSDatabase.ExecuteNonQuery ("Subscriber Integer Primary Key Attribute, Name Text (50) No, Number, Date First Text (30)");); There is no difference when I try to use the methods of CSConfig and when I cscfif If I try to pass 3 aggregates to STDB (3) then I get the invalid ...

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...
