Selection: Validating User Input Goal of Part 2: Experience with implementing control structures from a flow chart for the purpose of user validation. Requirements Did you come prepared? o Control Structures - Selection videos, ideally all done! Collaboration. o You will be discussing and working together in small groups, hopefully the same as last time (attendance and technology permitting!). o Someone will submitting a completed Python code file for marks include all group members names! Validation Code Example Using isnumeric() # Display message: "Please enter the number of sales for this salesperson: " # Attempt to store the user input in variable sale_amount sale_amount = input('Please enter the number of sales: )) if sale_amount.isnumeric(): sale_amount = int(sale_amount) isvalid = True else: isvalid = False # If sale_amount was not stored successfully if not isvalid: # display message, "Sorry, the number of sales must be a whole number" print('Sorry, the number of sales must be a positive whole number.') else: # Otherwise, carry on with processing/output Validation Code Example Using Try / Except # Display message: "Please enter the gross sales for this salesperson: $" # Attempt to store the user input in variable gross_sales try: gross_sales = float(input('Please enter the gross sales: $')) isvalid = True except: isvalid = False # If gross_sales was not stored successfully if not isvalid: # display message, "Sorry, the gross sales must be a positive number" print('Sorry, the gross sales must be entered as a positive number.') else: # Otherwise, carry on with processing/output
