Memory allocation is the process of granting and allocating memory when an application requests it. The python runtime automatically allocates memory for your objects, such as lists, dictionaries, etc. It does this by requesting memory from your operating system. An application cannot use memory that is not allocated. In some programming languages, like C , the programmer is responsible for mem...
