Stock_sales_quantity_calculator.py

#A Python program that asks the user to enter the following data:

#An initial stock level for a product
#The number of month(s) to plan
#The planned sales quantity for each month
#Based on this data, calculate the required production quantity as follows:

#If the sales quantity is smaller than the stock level of the previous month, the production quantity is 0
#If the sales quantity is larger than the stock level of the previous month, the production quantity is this difference
