Hope that now you got familiar with the syntax of Python. Now let’s start programming in Python.

The procedure to save and run a Python program is as follows:

1. Open your favorite editor (notepad, WordPad or notepad++)

2. Write the program code

3. Save it as a file with the filename mentioned. I follow the convention of having all Python programs saved with the extension .py

4. Run the interpreter with command, python program.py

or

use IDLE to run the programs (here as an easiest way to do programming

First let us try in IDLE

For this, Open IDLE and then go to file>> New file

Now enter the codes for your program

i=5 print i i=i+1 print i s="this is my first prigram" print s

Now save it and Run by using the option in the menu (Run>> Run Module) or hit F5

You wil get something like the below picture

You can run Python progems in many ways

1. from your command prompt

Here you can just give " python <input_program_name .py> "

2. from terminal also " python <input_program_name .py> "

3. If you need to use the program variable just type: import_name_of_program_without_py

[ note that every program in python can also be considered as module]

4 When you are inside python, you can execute a program by

exec(open('filename.py').read())

5.

IMPORTANT :: FORGET CURLY BRACES

Whitespace at the beginning of the line is called indentation. Leading whitespace (spaces and tabs) at the beginning of the logical line is used to determine the indentation level of the logical line, which in turn is used to determine the grouping of statements. This means that statements which go together must have the same indentation. Each such set of statements is called a block.

You can also use indents to have a good look for the program (Use of tabs instead of spaces are recommended)
