Data can come from a variety of sources and it can be stored in various manners . Like for example , we can store data in a list , in a dictionary , or in a string . The question hence is how to sort data , when one needs to do so ?

In python , instead of creating our own sorting algorithm , or our own sorting function , we can use the sorted function , which has a worst case performance – of O(n log n ).

The man-db package is used to search for documentation under Linux . It is used by Debian , fedora , and other Linux distributions .

The man-db package contains the binaries which are used for searching and for reading the documentation :

whatis , apropos , man

It also contains utilities used to maintain the documentation:

mandb , manpath , smanpath.config

This article will explain , what is the manual , the manual section , the manual page . It will also explain what is the man-db package and what is whatis , apropos and the man commands .

An object has a type which defines its attributes and methods . For example the str type define the attributes and method for a string object.

An object has also an id which is its memory address , and a value for example 1 or 'a' …

To compare objects in python , we can implement python comparison methods __eq__ , __ne__ , __lt__ , __gt__ , __ge__ , __le__ . In this article we will show how to implement these methods and how they work .

In macOS there are some standard directories which can be in one of the user , local , system or network domains . There are also some standard Unix/Posix like directories .

This article will start by explaining what is the user , local , system and network domain . After that it will explicate the standard directories that belongs to these domains. Next it will explain what are the Unix/posix like standard directories . Finally it will elucidate the other macos directories .

The limits.h header was defined as part of the c89 standard .

It contains the min and max limits that integer types can have on a certain machine . It also defines the number of bits in a char , and the maximum number of bytes in a multibyte characters .

There are three kinds of integer literals in c . They are the decimal , octal and hexadecimal .

The Integer literals can be of the int , long , and long long type , and they can be either signed or unsigned .
