A program that accepts insurance policy data, including a policy number, customer last name, customer first name, age, premium d

valentina_108 [34]

Answer:

policy_num = int(input("Enter policy number: "))
lastName = input("Enter last name: ")
firstName = input("Enter first name: ")
premiumDate = input("Enter premius due date (mm/dd/yyyy): ")
numAcc = int(input("Enter number of driver accident in the past three years: "))
if(policy_num <1000 or policy_num > 9999):
policy_num = 0
dateComp = premiumDate.split("/")
month = int(dateComp[0])
day = int(dateComp[1])
year = int(dateComp[2])
if(month < 1 or month > 12):
month = 0
day = 0
year = 0
else:
if(month == 1 or month == 3 or month == 5 or month == 7 or month == 8 or month == 10 or month == 12):
if(day < 1 or day > 31):
month = 0
day = 0
year = 0
elif(month == 4 or month == 6 or month == 9 or month == 11):
if(day <1 or day > 30):
month = 0
day = 0
year = 0
elif(month == 2):
if(day < 1 or day > 29):
month = 0
day = 0
year = 0
print("Policy number: " + str(policy_num))
print("Last name: " + lastName)
print("First name: " + firstName)
print("Premium Date: " + str(month) + "/" + str(day) + "/" + str(year))
print("Number of driver accidentin the last three years: " + str(numAcc))

Explanation:

The solution code is written in Python 3.

Firstly use input function to prompt user to enter all the necessary insurance policy data (Line 1 - 5).

Next create an if statement to validate the input policy number. If the policy number is not within the range of 1000 - 9999, set the policy number to zero (Line 7 -8).

Next, split the input premium date into month, day and year (Line 10 -13). It is followed by checking the month if it is between 1 - 12. If not, set the month, day and year to zero (Line 15 - 18). Otherwise the program will proceed to validate the month based on the maximum and minimum number of days for a particular month (Line 20 - 34). If the day is out of range, set month, day and year to zero.

Lastly, use print function to display the policy data (Line 36 - 40).
