if user gives float, string or less than one like [0, -1, "2", 3.2] then the input is rejected
Also the user is expected to give values within [1 <= value <=200]

only accepts data for valid int and float values.

while taking input from user we use same module to handle input and only valid int type is accepted.


[Adding flowers to cart]

your cart. The bouquet size is subtracted by valid order quantity given. Meanwhile availability of stock is also
considered.
