For Python_In_Tamil-002, the topic is Python Statements.

Python statements are instructions or commands that perform actions, control program flow, or manipulate data.
 Assignment Statements:
age = 35
print(age)

print("x is less than 10")

 Loop Statements:
for i in range(6):
print(i)

x = 5
while x > 0:
print(x)
x -= 1

 Function Definition Statements:
def greet(name):
print("Hello, " + name)
greet(β€˜Govi’)

 Return Statement:

except ZeroDivisionError:
print("Division by zero is not allowed.")

 Break and Continue Statements:

Dear All,
I am Govindarajan from Thanjavur. I teach Basic Python through OnLine. I am a PCEP and PCAP.
Ok, let us start learning Basic Python.

  1. Install python from python.org as per your computer system.

  2. In windows, in the search bar, type cmd, cmd page will get opened. Write python at the cursor location and press Enter. If you see Python with the version number of the python, then it is confirmed that python is installed in your system. If not, go to the point number 1 above.

  3. Then, in the search bar, type IDLE. Click on IDLE with right side mouse and click Run as administrator. you will see a new window titled as IDLE Shell python version number. This window is called as Shell window or Console window.

  4. In the shell window, click File => New File. Another window with a title as untitled will open. This window is called as Editor window. we will write all our codes/program in this Editor window. It will be saved as python file(.py extension).

  5. Type ('Hello World') with a file name as BP001, save it(Ctrl + s), click Run, click Run Module F5 (or Fn + F5), the code will get executed and you will see Hello World in your Shell Window.

  6. Great !!!. You have successfully completed your first program in Python. Congratulations.

Let us meet tomorrow in 'Python_In_Tamil-002'.

Thanks and Regards.
Govi.
