3. Working in Script
mode
For writing lengthy programs in Python, Script
mode is used. Using this mode, we can create and
edit Python programs. In this mode, we can save
our file so that it can be used later. The complete
script is written in an editor, such as a Notepad in
Windows.
Step-1: File New
🡪

4. Step-2: The new
Script mode opens

5. Step-3: Type the
python program
Step-4: Save the
python program
.py is the
extension for
PYTHON files.

10.function

11. input() function
⮚ Input function is used to accept the
value for a variable from the user. To
input integer and float values, we
can use int() or float() along with
input().
⮚ In python, input() function takes
one string argument. This means
that whatever values is being
entered by the user, it will be taken
as a string argument.

12. It doesn’t display
sum rather the
numbers are
displayed together
and are printed as
string.

13. Write a Python program to read school name and
grade, display in which grade he/she will be studying
after two years.
Then
how do
we
do?????

14. It is displaying sum.
As the int function
has converted
string to integer.
Thus addition is
possible.
int function is used to
convert string to integer
value.

15. Program to swap two numbers

16. 1. Write a program to calculate 5% discount on total purchase of
stationery.
2. Write a program to convert miles into kilometers.
1mile=1.6 km
3. Write a program to convert temperature from Fahrenheit to Celsius.
Celsius=(Fahrenheit-32) * 5/9

17. Features of print() function
🞇The print() function in python is used to print
a message or value on the output device.
🞇It converts the message or an object into a
string before writing it on the screen.
🞇It can have multiple parameters.
🞇It supports multiple escape sequences to
format the output,
eg., ‘n’- new line
‘t’ – tab space
‘r’ – carriage return.

18. Comma operator as separator in print
function.

19. Tab space, new line and carriage return.

20. int () and float() functions are used to convert string to integer or float
