The flowers are identified using name, price per kg and stock available (in kgs).
Write a Python program to implement the above requirement.

Attributes
(private)
flower_name
price_per_kg
stock_available

Methods
(public)	__init__()	Create and initialize all instance variables to None
validate_flower()	Return true, if flower name is valid. Else, return false
(Refer table for valid flower names)
validate_stock(required_quantity)	Accept the quantity required. Return true, if stock is available.
Else return false.
sell_flower(required_quantity))	Accept the quantity required.
Validate flower name and stock.
If both are valid, update stock available based on the quantity required
check_level()	Check if available stock is below the order level
If so, return true. Else, return false
(Refer table for order level of each flower)
setter methods	Include setter methods for all instance variables to set its values
getter methods	Include getter methods for all instance variables to get its values
Note: Perform case insensitive string comparison
Represent few flowers, initialize instance variables using setter methods, invoke appropriate methods and test your program.
