Python Class 2 - Download and Install Python

Download and Install Python, download python interpreter, install python software, set python environment variable, lunch Python IDLE, write & run programs.

Python is a free and open-source programming language, and you can get Python source code easily.

Before you start, you will need Python on your computer.

Check whether you already have an up-to-date version of Python installed by entering python in a command-line window.

Note: Python comes preinstalled on most Linux distributions, and is available as a package on all others.

To install Python Interpreter on your computer (MS Windows):

Python Class 2: Python Download and Installation

Python Installation:

> Launch Python Website (python.org)
> Download your operating system compatible 'Python Software'
> Install the Software and set the Path while installation.
> Launch Python IDLE (Python Shell)
> Write a sample program and run.

Two modes of programming in Python.
1. Interactive Mode
2. Script/File Mode

Example:

x=100
y=20
print (x+y) #120
print ('Hello')
print ("Hello")
print ('''Hello''')
print ("""Hello""")


if x>y:
print ("X is Big Number")
print ("Python")

x=100
print(x) #100

x=10.23
print(x) #10.23

x=True
print(x) #True

x="India"
print(x) #India
