Topics for Python - Basics

=====================

 

1)     Syntax

 *   Python is very popular because of its simplicity to use and understand

 *   Simplicity of Python programming language lies in its syntax

 *   Python does not follow any complicated formats for writing of codes

 *  Syntax of Python quite different from other languages like C, C++, Java etc and      much easier to comprehend

 

2)     Variables

 *  If one is familiar over the manner in which variables can be declared over any Python program then the topic of manner and efficient declaration of variables can also be done efficiently

 

3)     Operators

 *   Operators are the symbols that represent a particular action or process .

*  One can explore different mathematical operators and calculations that can happen using the available operators in Python

 

4)     Data Structures

 *   Data Structures are the most important concept of any programming language

 *  Data Structures are the building blocks of any programming language as all             programming languages deal with objects creation which deal with memory      allocation , memory deallocation and memory utilisation of the variables / objects using the relevant data structures for carrying out the necessary operations that are needed to be performed as per the program that one is working upon

 *  Python has especially these four data structures that are lists , sets , dictionaries and tuples .

 *   One can get to have a good understanding of the manner in which each of the above listed data structures are put to use in advanced examples which would discuss the manner in which append , deletion or structural operations take over a given data structure .

 *  The most important concepts of Python that need to be used and understood are the following :

 

1)     Decision Making Statements :

 

If , If-else , Nested If else , chained conditionals of the else if type of statements , single statement conditions all come under the category of decision-making statements . Along with earning , one may also have to practice 10+ coding problems on a daily basis which would help someone get familiar with the  manner in which one can scale up on the level of complexity of the programs and their creation

 

2)     Loops :

 

Loops are the structures that repeat a sequence of instructions . Python deals with while loops , for loops and nested loops . Along with these one may also learn loop control statements which show the manner in which loops can be initialised , implemented , interjected and put to end in the desired way of the programmer .

 

3)     Functions in Python

 Functions are the smaller pieces of code that perform some desired task . Python has four different types of functions that are User Defined functions , Built-In functions , Lambda functions and Recursion functions mainly .

 

We will just put a small recap over Functions in Python :

 

User Defined functions are those functions which a user  / programmer writes himself which takes programming constructs and statements to write a function which would achieve a desired result at the end of the function which may include the use of some built-in functions into the overall function code construct . 

Built-In functions are those functions which are created as a part of the programme package at the time of creation of the Program package and its default libraries which come together with the program at the beginning of the program package .

Lambda functions are also some form of user defined function , however the construct is limited to only one line and this usually does the work of iteration over the elements of the function , access the individual elements , or use the functions to iteratively append , retrieve or delete some elements over an existing structure or a dummy/temporary structure .

  

*  Along with the the basic concepts of the scripting part of the Python Language one also needs to have a good understanding of implementation as well as creation of features in Object Oriented Language features of Python :

 

1)     Polymorphism

2)     Inheritance

3)     Encapsulation

4)     Abstraction

 

All these aspects of Programming in Python and how the same are going to  be used in Python for Data Science and Machine Learning Modelling would be

discussed in further blogs . As I am getting disarrayed due to a some intermittent problems over my laptop I am not able to implement some of the important Algorithms and Modellling Processes . But soon , I hope to get these started on a better level .
