Basic Elements of a Program
Variables:
These are the data container, which various
types of data, like counter information, user information, file
information, etc.
Example - int, string.
Loops:
It is a block which includes
repetition of certain instruction under few circumstances.
Example - For loop, While
loop.
Conditionals:
It is a block that allows the program to be
executed only under certain conditions.
Example - If-Else
block.
Input/Output:
Data sharing among various resources, like user
or external file.
Example - User input function
or File input/output function.
Subroutines and functions: These are
the modules or sets of modules that are frequently used over the
complete program.
Example - Library
function.
What is Python?
Python is a general-purpose programming
language.
It is type inferred i.e it automatically infers the
data types.
It gets interpreted.
How it is used?
Install Python from Official website -
https://www.python.org/downloads/
Open Python from the program.
Execute commands on the console.
Use of variable
A variable is used to store the data.
A variable can be declared in python by simply naming
it and initializing it.
Example: Num = 21
Use of Expression
An expression is a combination of keyboard letters
which can consist of data variables, operators, symbols etch to
give the result.
Example: Sum = 10 + Num
Use of Statement
A statement is an independent line in a program
that contributes to the result of a program.
It is a building block of a program, a set of
statements that build a program.
Example: print(Sum)
Use of indentation
Python requires a proper indentation, in order to
mention the extent of a block.
For example:
if i <
10:
print('Inside If')
print('Outside If')

Distinguishing Between Inferences and Assumptions To be skilled in critical thinking is to be able to take one’s thinking apart systematically, to analyze each part, assess it for quality and then improve it. The first step in this process is understanding the parts of thinking, or elements of reasoning. These elements are: purpose, question, information, inference, assumption, point of view, concepts, and implications. They are present in the mind whenever we reason. To take command of our thinking, we need...
