Performance of Python Programming

[psbasha]

Hi,

Since in other languages we have pointer concept and we allocate memory and deallocate memory for various variables .So there will not be much memory consumption.But in case of Python we dont have memory allocation concept to variables,then what will be the memory consumption and performance of the applications developed.


Thanks in advance

High level languages such as Java and Python use a thing called garbage collecting (gc). What the engine does is count the number of references to a variable. When that count reaches zero, the varable is marked for gc. Every so often the engine goes through and frees memory use by variable that no are longer being used.
You can use

del anyVariable

to free memory imediately (often used for large variables that are no longer needed).

actually del just removes the name from the namespace. see here . The memory is not reclaimed until later. ( not sure for latest version of Python though)
