WHY LEARN PYTHON?

There are hundreds of programming languages in the world. Every general purpose programming language has different features and capabilities. We will see the applications of Python programming language later in the article. But for now, let's enlighten the seven golden factors which says that you should be using Python Programming language:

1. Easy to learn
2. Open source license
3. Portable
4. Large standard libraries
5. High level-Interpreted language
6. Extensible and Embeddable
7. Object oriented language 

APPLICATION OF PYTHON 

Python is in the list of most demanding programming languages nowadays and for the future as well. Python is a general purpose programming language which is capable of providing tons of complex functionalities very conveniently. In the industry of computing and technology, Python is mostly used for the following purposes:

• Web Development
• Mathematics Computations
• Data Sciences
• Artificial Intelligence
• Graphical user interface Applications

INSTALLING IDE FOR PYTHON

IDE stands for Integrated Development Environment. Python does not necessarily required an IDE. Python scripts can be written on any text editor or even on notepad and run through the terminal. An IDE provides a lot more functionalities than using terminal and notepad such as debugging, coding and running at run-time, and many other tools for making your programming environment much more convenient. We will be using Python official IDE, IDLE. However, you can download and install any of the IDE from the following:

• IDLE
• Wing IDE
• Pycharm IDE
• Notepad++
• Atom IDE
• Spyder IDE 

 

HOW SIMPLE IS PYTHON?

Python is not as complex as other programming languages. It has clean and easy ways of programming. For instance if you want to add any two numbers you can simply write:

2 + 3 

 

 And the result or output will print on the screen;

Similarly if you want to print any value either any number or a string you will simply type:

print ("Howtechyy") 

#or 

print ('Howtechyy')

print (5)

 

RESULT:

 

PYTHON SCRIPTS

Python scripting is used to avoid the same coding again and again. In Python scripting, a python program is written and saved. Now, Whenever the programmer needs to use or execute the same program or logic, script is used. For instance, type the following code in your IDE or notepad and save this file as Script.py.

IN LINUX:

#!/usr/bin/python

print ("Hello Howtechyy")

IN WINDOWS AND MAC:

 

#File: Script.py

print ("Hello Howtechyy")

Now open up the terminal and use the script. Simple type the following without coding entire program:

Python Script.py

MOST COMMON PYTHON COMMANDS FOR CALCULATION

abs(value) : For absolute values

ceil(value) : To round the value up

floor(value) : To round the value down

round(value) : For rounding off value

cos(value) : For Cos trigonometric values

sin(value) : For Sin trigonometric values

log(value) : For finding logarithm

log10(value) : For finding Log10

max(value1, value2) : For finding the largest value

min(value1, value2) : For finding the smallest value

sqrt(value) : For finding square root

COMMENTS IN PYTHON

  Comments in Python are the statements, written between the code to make it meaningful and clear. Comments are not executable and ignored by the compiler. The syntax for inserting comment in python is as follows:

#comment

Comments in Python can be used as follows:

VARIABLES IN PYTHON

Variables are the stores for storing different kinds of values for your program. Python does not makes the program complex for a programmer. For instance, data types are not declared in the program of python instead, we can simply assign any sort of value to any kind of data. The syntax depends on the kind of value you want to declare. For instance, strings are declared in inverted comas while integer or numeric values are declared as they are.

NUMERIC VALUES IN PYTHON

We can assign any numeric value to a variable as it is. The syntax for assigning numeric values in python is:

var1 = 5 (any integer value)

var2 = 5.55 (any float value)

For example:

 BONUS INFO:

It is not necessary to type print function in order to print a value, instead it is also possible to get a print output, just by typing the name of the variable(such that var1).

 

STRINGS IN PYTHON

There are two syntax available for the declaration of strings in Python programming language. The difference between both of the syntax is of inverted commas.

name1 = "HowTechyy"

 Or strings in Python can also be declared as follows:

name2 = 'HowTechyy'

In practice:
