global

for example: assginment statement will declare a new local variable. foo = 'global' def func1(): foo = 'func1' def func2(): foo = 'local variable in func2' use global declaration will use the foo in global: def func2(): global foo foo = 'global changed in func2' #changed the foo value in global scope how can I change the variable foo in func1 scope? Thanks for any help. Edit: Thank you Brandon Craig Rhodes, I finally understand your meaning. if there are more than 3 scopes nested, I can store the variable in a list. foo = ['global', 'function1', 'function2'] def func1(): foo[1] = 'func1' def

how can i require a module globally so i can use it in different modules without having to require it again? or do i just have to do that everytime? is there any best practice for this? heres an example of what i am talking about. lets say i have an index.js like this: var a = require('a.js'), utils = require('utils.js'); var str = 'hello this is a test'; str = a.change(str); utils.return(str); a.js var utils = require('utils.js'); exports.change = function(str) { str = str.replace('test', 'example'); utils.return('i changed test to example!'); return str; } utils.js exports.return = function

I want to declare some global variables and global constants. Normally, I would put them in the includes/global.php of my own custom framework. Where should I define globals in CodeIgniter? Here's an example of the globals I want to declare: define('USERSTAT_OFFLINE', 0); define('USERSTAT_ONLINE', 1); define('USERSTAT_AWAY', 2); define('USERSTAT_BUSY', 3); $PAYMENT_PLANS = array(); $PAYMENT_PLANS[] = array('id'=>1, 'name'=>'Trial'); $PAYMENT_PLANS[] = array('id'=>2, 'name'=>'Premium Plan'); You may utilise config file ( system/application/config/config.php ) to set configuration related

I have to cache an object hierarchy in-memory for performance reasons, which reflects a simple database table with columns (ObjectID, ParentObjectID, Timestamp) and view CurrentObjectHierarchy. I query the CurrentObjectHierarchy and use a hash table to cache the current parents of each object for quickly looking up the parent object ID, given any object ID. Querying the database table and constructing the cache is a 77ms operation on average, and ideally this refresh occurs only when a method in my database API is called that would change the hierarchy (adding/removing/reparenting an object).
