mysql - Do I need to close a database connection in a short python script? -

-

What dragon (version 2.7, 3.3) closes the database connection immediately after a program finishes?

For example: 

  Import MySQLdb conn = sqlite3.connect (host = "localost", user = "adam", password = "12345", db = "My_db") c = conn.cursor () c.execute ('SELECT * FROM MY_TABLE' '') cur.close () # Do I really need it? Conn.close () # Do I really need it?   
 If I could have a problem with shutting down the connection to run this script again once again?  
 ps Yes, I know that the best practice is to stop all the resources.  
 
 As you have said that you should close the connection to your code explicitly  < P> SQLite will return any open transaction for example.  
 In addition to this I have read somewhere you can use the  statement with  when you are using MYSQL, Google may be worth googling.

You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...

Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
