PYTHON INSTALLATION

Python current version is 3.14.6

Python is a Forward compatibility

In Linux default there is a python we can access the python through terminal

In window we have to download the python.

python.org--->python--->download.

After download and installation in windows we have to type the IDLE.

What is IDLE ?

IDLE stands for Integrated Development and Learning Environment.

It will give the result immediately when you begin the code

The shell is a interactive interpreter

It provide the output for each line of the code immediately.
EXAPMPLE PROGRAM:

5+10
output: 15

25/10
output:2.5

Advantage of python is we need not to declare data type like other programming Language.

name="shobi"
print("Welcome", name, "!")
output:
Welcome shobi !

name="shobi"
print("Welcome"+name+"!")
output:
Welcomeshobi!

Both are the same program but the difference is in 1st program i used (,) in a print. 2nd program i used(+) in a print

if i give a (,) means it give the space

if i give a(+) means it doesnot give the space it will concatenate .

name ---> reference variable/identifier
print----> Function (action)
= ----> Assignment Operator it will assign the right side value to the left side reference variable.

FUNCTION OVERLOADING:

Same Function name but different type of arguments
For Eg:

The above program has the same function name print but different type of arguments like in 1st program we use a (,) in 2nd program we use a (+).
