# How many units of KPLC do you use per month?
# Go to https://www.stimatracker.com/, click on `prepaid`, then enter amount in KES you use per month.
# Click `calculate`, it will give you your consumption in kwh. Mine is KES 5000, which give ~150kwh

monthly_kplc_cost = 5000 # KES
price_per_kwh = 33 # kes per unit
consumption_per_month = int(monthly_kplc_cost/price_per_kwh) # kWh 
assert consumption_per_month == 151 # kwh
consumption_per_month = 150 * 1000 # watt-hours

# - OOPs helps users to understand the software easily,dont need to know actual implementation.
# - increase readability, maintainability of code.
# - Procedural programming specifies the steps a program must take to reach the desired state, usually read in order from top to bottom.

# (a) encapsulation - bundling up attributes & methods that operate on data into a single unit(eg, class)
# (b) abstraction   - showing only essential info, hide implementation detail.
# (c) inheritance   - derived class can inherit properties and behaviour
# (d) polymorphism  - ability of obj to take many forms. different classes can be treated as an obj of a common type.

# access specifiers: public, private, etc
