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).

(i) A pair is a compound data type that holds two other pieces of data. The two ways of representing the pair data type.
(ii) The first way is using List construct and the second way to implement pairs is with the tuple construct.

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

(i) Line plot
(ii) Scatter plot
(iii) Histogram
(iv) Box plot
(v) Bar chart and
(vi) Pie chart

To populate the table "INSERT" command is passed to SQLite."execute" method executes the SQL command to perform some action.
Example:
Sql_command =" " INSERT INTO student (Rollno, Sname, Grade, Gender, Average, birth_date) values (NULL, "Akshay", "B", "M", "87.8", "2001-12-12");" " cursor.execute(sql_command)

Users of database can be human users or programmers, other programs or applications.

Modular programming is a software design technique to split our code into separate parts. These parts are called modules. The focus for this separation should have modules with no or just few dependencies upon other modules.

(i) The theoretical difference between the two is that scripting languages do not require the compilation step and are rather interpreted.
(ii) For example, normally, a C++ program needs to be compiled before running whereas, a scripting language like JavaScript or Python need not be compiled.
(iii) A scripting language requires an interpreter while a programming language requires a compiler. 

The default is reading in text mode. In this mode, while reading from the file the data would be in the format of strings.

Database normalization was first proposed by Dr.Edgar F Codd as an integral part of RDBMS in order to reduce data redundancy and improve data integrity. These rules are known as E FCodd Rules.

(i) SQL server
(ii) Oracle
(iii) MySql
(iv) Maria DB
(v) SQLite.

(i) "Init" is a special function begin an end with double underscore in Python act as a Constructor .
(ii) Constructor function will automatically executed when an object is created.
General format of __init__ method
                                    (Constructor function)
def __init__ (self, [args........])
<statements>

Once a class is created, next to create an object or instance of that class. This process of creating object is called as "Class Instantiation".

Syntax:
# Tuple with n number elements
Tuple_Name (E1, E2, E3.......En)
# Elements of a tuple without parenthesis
Tuple_Name = El, E2, E3 ................. En

Python will not allow deleting a particular character in a string. Whereas you can remove entire string variable using del command.
Example :
>>> strl="How about you"
>>> print (str1)
        How about you
>>> del str1
>>> print (str1)
Traceback (most recent call last):
         File "", line 1, in
                 print (strl)
NameError : name 'str1' is not defined

(i) String is a data type in python, which is used to handle array of characters.
(ii) String is a sequence of Unicode characters that may be a combination of letters, numbers, or special symbols enclosed within single, double or even triple quotes.
(iii) Example :
Welcome to learning Python"
"Welcome to learning Python"
""Welcome to learning Python""

(i)  A recursive function calls itself.
(ii) The condition that is applied in any recursive function is known as base condition.
(iii)  A base condition is must in every recursive function otherwise it will continue to execute like an infinite loop.

(i) User defined functions.
(ii) Built in functions.
(iii) Lambda functions.
(iv) Recursion functions.

The range() is a built-in function, to generate series of values between two numeric intervals.
The syntax of range() is as follows:
range (start,stop,[step])
Where,
start - refers to the initial value
stop - refers to the final value
step - refers to increment value, this is optional part.

The break statement terminates the loop containing it. Control of the program flows to the statement immediately after the body of the loop.

An Exponent data contains decimal digit part, decimal point, exponent part followed by one or more digits.

Python breaks each logical line into a sequence of elementary lexical components known as Tokens. The normal token types are
(i) Identifiers,
(ii) Keywords,
(iii) Operators,
(iv) Delimiters and
(v) Literals.

The process of binding a variable name with an object is called mapping = (equal to sign) is used in programming languages to map the variable and object.

List is constructed by placing expressions within square brackets separated by commas. List can store multiple values.
Example:
1st := [10, 20]
x, y:= 1st
In the above example x will become 10 and y will become 20.

(i) Subroutines are the basic building blocks of computer programs. Subroutines are small sections of code that are used to perform a particular task that can be used repeatedly.
(ii) In Programming languages these subroutines are called as Functions.
