We can install Matplotlib using Pip. Pip is a management software for installing Python packages.

(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)

If a column of a table is declared to be an INTEGER PRIMARY KEY, then whenever a NULL is used as an input for this column, the NULL will be automatically converted into an integer which will be one larger than the highest value so far used in that column.

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.

S.No	Compiler	Interpreter
(i)	It takes an entire Program at a time.	It takes a single line of code or instruction at a time.
(ii)	Display all errors after compilation, all at the	Displays error of each line one by one.

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

Command Description Component Insert Inserts data into a table DML Create To create tables in the database DML  

Table Constraints	column constraints
Table constraint is apply to a group of one or more columns.	Column constraint can be apply only to individual columns.

Hierarichal data Model	Network data model
In Hierarchical model, a child record has only one parent node	In a Network model, a child may have many parent nodes,
It Hierarchical model, data is represented as a simple tree like structure form.	It represents the data in many-to-many lationships.

 

Destructor is also a special method to destroy the objects. In Python,__del__( ) method is used as destructor. It is just opposite to constructor.

Output:
>>>
10
line 7, in <module>
print(S._num)
AttributeError: 'Sample' object has no attribute '_num'
>>>

(i) In Python, a set is another type of collection data type. A'Set is a mutable and an unordered collection of elements without duplicates.
(ii) That means the elements within a set cannot be repeated. This feature used to include membership testing and eliminating duplicate elements.

Main advantages of functions are
(i) It avoids repetition and makes a high degree of code reusing.
(ii) It provides better modularity for your application.

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

Syntax:
if < condition >:
          statements-block 1
else:
          statements-block 2

Sorting is a method of arranging group of items in ascending or descending order. Various sorting techniques in algorithms are Bubble sort, Quick sort, Heap sort, Selection sort, Insertion sort.

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

The different operators that can be used in python are
(i) Arithmetic operators
(ii) Relational or Comparative operator
(iii) Logical operators
(iv) Assignment operators
(v) Conditional operator

Namespaces are containers for mapping names of variables to objects.
Example : a : =5
Here the variable 'a' is mapped to the value '5.

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.

Interface	Implementation
Interface just defines what an object can do, but won't actually do it.	Implementation carriers out the instructions defined in the interface.

X: = (78) has an expression in it but (78) is not itself an expression. Rather, it is a function definition. Definitions bind values to names, in this case the value 78 being bound to the name 'X'.
