Python programming language is simple, readable, and it closely resembles English. Python is also a well-documented language; some of these facts make us believe that Training on Python is certainly worth considering when trying to find the core technologies for the next project.

An essential part of learning Python Programming is to understand the special components used in Python. A Python code is made up of Functions, Statements, Expressions, and many more. These are the components of the Python module or the Structure of the Python module. After learning these components, it’s easy to start your Python Programming career.


Components of Python are very essential because they make up the Python code. They are the basics of Python coding and are used in every Python Program block. In general, when compared to other programming languages we can easily analyze Python Programming. 


There are many components of python that make it a high-level programming language. The most important components are as follows:


1) Expression: An Expression is a phrase of code that Python assesses to produce a value. The simplest expressions are literals and identifiers. You build different expressions by getting sub expressions together with the operators and delimiters.

For example:

>>> 1+1


Even though expressions contain values, variables, and operators, not every expression contains all of these elements. A value all by itself is viewed as an expression, as is a variable. At the point when the Python interpreter displays the value of an expression, it utilizes a similar format you would use to enter a value.

In the case of strings implies that it includes quotation marks. But if you use a print statement, Python shows the contents of the string without the quotation marks.


2) Statements: It is a logical unit of code that can be executed by the Python interpreter. At the point when we type the statement at the command prompt, it will execute the code in the statement and give the result, as long as the code is error-free. In general, the programming code saved in the document contains scripts; these scripts are a combination of statements to perform units of work.


3) Comments: As programs get bigger and more complicated, they get harder to read. Formal languages are thick, and it is frequently hard to take a look at a piece of code and sort out what it is doing, or why.

For example: 

Percentage = (minute * 100) / 60 #caution: integer division

“#caution: integer division” is the comment in the program. Everything from the # to the end of the line is ignored; it has no impact on the program. The comment is intended for the programmer or for future developers who may utilize this code. The above-quoted example reminds the reader about the ever-surprising behavior of number division.


4) Functions: Functions are a convenient strategy to separate your code into useful blocks, permitting us to arrange our code, make it more readable, reuse it, and save some time. Also, functions are a key way to characterize interfaces so programmers can share their code.


5) Blocks and Indentation: One of the most distinctive features of Python is its utilization of indentation to mark blocks of code. Consider the ‘if-statement’ from our simple password-checking program:

 For example:

If pwd == ‘apple’:

                  print (‘Logging on.......’)


                  print (‘Incorrect password.’)

print (‘All Done’)

The lines print ('Logging on ...') and print ('Incorrect password.') are two different code blocks. These end up being just a single line long, yet Python allows you to write code blocks comprising quite a few statements.

To indicate a block of code in Python, you should indent each line of the block by a similar sum. The two blocks of code in our example if-statement are both indented four spaces, which is a common measure of space for Python. 


Training on Python
