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

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)

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.

Python enables reverse or negative indexing for the list elements. Thus, python lists index in opposite order. The python sets -1 as the index value for the last element in list and -2 for the preceding element and so on. This is called as Reverse Indexing.

Strings in python are immutable. That means, once you define a string moditications or deletion is not allowed. However, we can replace the existing string entirely with the new string.

A variable with global scope can be used anywhere in the program. It can be created by defining a variable outside the scope of any function.

Scope of variable refers to the part of the program, where it is accessible, i.e., area where the variables can refer (use) it. The scope holds the current set of variables and their values. The two types of scopes - local scope and global scope.

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

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

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.

Algorist may refer to,
1. A person skilled in the technique of performing basic decimal arithmetic, known as algorism.
2. A person skilled in the design of algorithms.
3. An algorithmic artist.

An algorithm is a finite set of instructions to accomplish a particular task. It is a step-by-step procedure for solving a given problem.

Literal is a raw data given in a variable or constant. In Python, there are various types of literals.
1) Numeric Literals:
Numeric Literals consists of digits and are immutable.
2) String Literals:
In Python a string literal is a sequence of characters surrounded by quotes.
3) Boolean Literals:
A Boolean literal can have any of the two values: True or False.

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

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.

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.

Scope should be used for a variable because; it limits a variables scope to a single definition. That is the variables are visible only to that part of the code. Essentially, variables are addresses to an object in memory. When you assign a variable with := to an instance (object), you're binding (or mapping) the variable to that instance. Multiple variables can be mapped to the same instance.

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'.

A function is a unit of code that is often defined within a greater code structure. Specifically, a function contains a set of code that works on many kinds of inputs, like variables, expressions and produces a concrete output.
