• python 'self' explained

  - by richzilla

  What is the purpose of the 'self' word in python. I understand it refers to the specific object created from that class, but i cant see why it explicitly needs to be added to very function as a parameter. To illustrate, in ruby, i could do this: class myClass def myFunc(name) @name = name end end Which i understand, quite easily, However in python i need to include self: class myClass: def myFunc(self, name): self.name = name Can anyone talk me through this? Any help would be appreciated.

Or, if the database uses a page-lock rather than a table/row lock?

Should I learn Perl for this? Or should I learn some kind of shell commands? The main concern is speed. If I need to write long code for such stuff, it defeats the purpose.
