Python Classroom notes 20/May/2026

Basics

• CPU executes the instructions
• Memory (RAM) is where the data lives

Datatypes

• Datatypes internally help in selecting memory and Datatypes help in writing logic
• We have Datatypes for
  • integers
  • float
  • boolean
  • text/string
• Now we have other types
  • list/array
  • class
  • struct
  • dictionary
• Speaking with Ria

Remember 10 as a
a = 10

Ria knows the following

• Arthimetic

+
-
*
// (integer division)
/
% (remainder)

• Logical

== equals
!= not equals
< lt
> gt
<= le
>= ge

• Assigment

Remember 10 as a
a = 10

Example-1

• Lets calculate simple intrest
• Prompt Show me how to calculate simple intrest step by step
• Lets speak with Ria (Logic)

Remember 10000 as p
Remember 5 as t
Remember 24 as r
calculate p * t * r / 100 and remember as simple_intrest
say simple_intrest

• Execution: Watch the class room video

Example – 2

• Lets make Ria convert Celcius to Farnhiet F = (C × 9/5) + 32

• Lets speak with Ria

Remember 42 as C
result = c * 9 / 5
result = result + 32
say result

• Exercises:
  • Convert kilos into pounds
  • Convert dollars into rupees
