This can cause memory corruption

Many languages operate on them behind the scenes, for example,
by placing an object in a memory location and automatically
creating a variable pointing to that object. The programmer can
use the object without knowing the address where the object is
stored in memory. The disadvantage of pointers is that not only
are they difficult to use, they can also be dangerous.
As a simple example, pointers allow you to insert some data into
memory that may already contain other data. causing the program
to crash. While avoiding explicit pointer manipulation makes
programming simpler and less dangerous, it also makes it
difficult for programmers to interact directly with the
computer's hardware and memory. Sometimes, for maximum speed and
efficiency, or when creating low-level programs such as device
drivers and operating systems, it is valuable to use pointer
direct memory addressing. This is one of the reasons why,
despite competition from more modern and user-friendly computer

languages, it remains one of the most
widely used and important of all programming languages. It also
explains why really good programmers (those who can write robust
programs that don't crash) are so valued. Finally this tutorial
is a quick overview of the language.

It certainly won't explain everything you need to know to write
good programs, but I hope it will give you an idea of the core
features of the language and help you understand why Python is
one of the most enduring programming languages. Page Last
