What is persistent cookie?

Persistent Cookie :
  • Also called a permanent cookie, or a stored cookie, a cookie that is stored on a user's hard drive until it expires (persistent cookies are set with expiration dates) or until the user deletes the cookie. 
  • Persistent cookies are used to collect identifying information about the user, such as Web surfing behavior or user preferences for a specific Web site.
  • A persistent cookie enables a website to remember you on subsequent visits, speeding up or enhancing your experience of services or functions offered.
  • For example, a website may offer its contents in different languages. On my first visit, I may choose to have the content delivered in French and the site may record that preference in a persistent cookie set on your browser. When you revisit that site it will use the cookie to ensure that the content is delivered in French.
Session Cookie :
  • Also called a transient cookie, a cookie that is erased when the user closes the Web browser. The session cookie is stored in temporary memory and is not retained after the browser is closed. Session cookies do not collect information from the user's computer.

What is composite key?

Composite Key : A composite key is a combination of two or more columns in a table that can be used to uniquely identify each row in the table. When the columns are combined uniqueness is guaranteed but when it taken individually it does not guarantee uniqueness. Sometimes more than one attributes are needed to uniquely identify an entity. A primary key that is made by the combination of more than one attribute is known as a composite key. Ex : Create table abc ( c1 int , c2 varchar(20), c3 varchar(100) , PRIMARY KEY ( c1, c2 ) );

What are the different data types in Python?

Python Datatypes : Boolean Numbers Strings Lists Tuples Sets Dictionaries Boolean : Booleans are either true or false. Python has 2 constants named True and False which can be used to assign a boolean value directly. In certain places ( like if statements ), Python expects an expression to a boolean value, these places are called boolean contexts. Numbers : Python supports both int and floating point numbers. Tuples : A tuple is an immutable list, it means a tuple can't be changed in a way once it's created. A tuple is defined in the same way as a list, except that the whole set of an element is enclosed in the parenthesis instead of square brackets. Similarities with the list  : Tuples have a defined order i.e. Indices are 0 based, so the first element of a non-empty tuple is always a_tuple[ 0 ]. Negative indices count from the end of the tuple. Slicing works too, when we slice a list we get a new list. When we slice a tuple, we get a new t

What is __repr__ function?

__repr__ function : The __repr__ function returns a string representation of a Python object that may be evaluated by the Python interpreter to instantiate another instance of the object. Called by the repr() built-in function and by string conversions (reverse quotes) to compute the "official" string representation of an object. repr() tries to convert everything into a string that can be used with eval() to re-generate the original object. repr() generates a computer friendly output. str() is used by print() function to generate a user-friendly output. str()'s output may or may not be used with eval(). >>> eval("'Hello'") 'Hello' >>> eval('Hello') Traceback (most recent call last):   File "<pyshell#8>", line 1, in <module>     eval(' Hello ')   File "<string>", line 1, in <module> NameError: name ' Hello ' is not defined
