The syntax for a table created with constraint is given as below
CREATE TABLE < table-name >
( < column namee-cdata type > [ < size > ]
< column constraint >,
( < column name > < data type > [ < size > ]
< column constraint >
< table constraint >( < column name >,
[ < column name > .... ]) .....
);

(i) A Data Manipulation Language (DML) is a computer programming language used for adding (inserting), removing (deleting), and modifying (updating) data in a database. In SQL, the data manipulation language comprises the SQL-data change statements, which modify stored data but not the schema of the database table.
(ii) After the database schema has been specified and the database has been created, the data can be manipulated using a set of procedures which are expressed by DML.

Oracle, MySQL, MS SQL Server, IBM DB2 and Microsoft Access are RDBMS packages.

General format of slice operation:
str[start:end]
Where start is the beginning index and end is the last index value of a character in the string. Python takes the end value less than one from the actual index specified.

DBMS Supports Transactions : It allows us to better handle and manage data integrity in real world applications where multi-threading is extensively used.

def display (a, b):
return a * * b
print (area (2, 5)
Output: 32

Matplotlib is the most popular data visualization library in Python. It allows to create charts in few lines of code.

cursor. description contains the details of each column headings. It will be stored as a tuple and the first one that is 0(zero) index refers to the column name. Using this command you can display the table's Field names.

Executing C++Program through Python
(i) Double click the run terminal of MinGW
(ii) Go to the folder where the Python software is located (Python.exe) is located.
For example here "Python" is located in

Constructor -( - - init - - ( ))
Destructor -(- - del - - ( ))

while test expression:
#code inside while loop

a = int (input("Enter any number :"))
x="even" if a%2==0 else "odd"
print (a, "is",x)
Output 1:
Enter any number  3
3 is odd
Output 2:
Enter any number: 22 
22 is even

The function dict ( ) is used to print the data in dictionary format without order

Syntax:
List.append (element to be added)
List.extend ([elements to be added])

(i) Mylist contains another list as an element. This type of list is known as "Nested List': Nested list is a list containing another list as an element.
(ii) Example: Mylist = [ "Welcome", 3.14, 10, [2,4,6] ]

Big Omega is the reverse Big O, if Big O is used to describe the upper bound (worst - case) of a asymptotic function, Big Omega is used to describe the lower bound (best-case).

An algorithm that yields expected output for a valid input is called an algorithmic solution

The input () function helps to enter data at run time by the user and the output function print () is used to display the result of the program on the screen after execution.

The LEGB rule is used to decide the order in which the scopes are to be searched for scope resolution. The scopes are listed below in terms of hierarchy (highest to lowest).

Person is referred to as a class or a type, while p1 is referred to as an object or an instance.

let square x
return: x * x
let i: = 0;
ifi < strlen> (s) then
-- Do something which doesn't affect s
++i

A list or Tuple can be converted as set by using set( ) function. This is very simple procedure. First you have to create a list or Tuple then, substitute its variable within set( ) function as argument.
Example:
MyList= [2, 4, 6, 8, 10]
MySet=set(MyList)
print(MySet)
Output:
{2, 4, 6, 8, 10}
