Must be in Python

Programming Project 8

The ISO 8601 Standard date format for Information Interchange indicates that a date be written as such:

                        YYYY-MM-DD

You are to write a program which converts dates for the user. The program allows a user to choose between:

* Enter a date in the business format   DD-MMMM-YYYY   (eg. 06-SEPT-2015 ) . The program will then print out the ISO 8601 representation of the date   (2015-09-06).

* Enter a date in ISO 8601 format (eg 2018-12-12), and print out the date in business format (12-DEC-2018)

Your program should handle user input errors such as:

* leading blanks

* blanks within the input string

Your program should delegate any large operations to functions which should be DEFINED AN IMPORTED MODULE

eg.) month conversion

Be sure you program contains a comment indicating your name, plus comments within the program indicating what is is happening. Each line does not need to be commented, just each group of lines that are completing a specific task.

Answer 1

Please find the code below::

def printMenu():
print("Enter following choice")
print("1. to convert date from business format to ISO 8601 representation")
print("2. to convert date from ISO 8601 representation format to business")
print("3. to exit")
  
def monthConversion(monthIn,mode):
month = ["JAN", "FEB", "MARCH", "APRIL", "MAY", "JUNE", "JULY", "AUG", "SEPT", "OCT", "NOV", "DEC"]
convt = ["01","02","03","04","05","06","07","08","09","10","11","12"]
if mode==1:
for i in range(12):
if month[i]==monthIn:
return convt[i]
elif mode==2:
for i in range(12):
if int(convt[i])==int(monthIn):
return month[i]
  
  
def convertDate(date,mode):
if mode==1:
dates = date.split("-")
dd = dates[0]
mmmm = dates[1]
yyyy = dates[2]
newMonth=monthConversion(mmmm,mode)
return yyyy+"-"+newMonth+"-"+dd
elif mode==2:
dates = date.split("-")
dd = dates[2]
mmmm = dates[1]
yyyy = dates[0]
newMonth=monthConversion(mmmm,mode)
return dd+"-"+newMonth+"-"+yyyy
  
  
if __name__ == '__main__':
while True:
printMenu()
choice = input("Enter your choice : ")
if choice=="1":
date = input("Enter date in business format DD-MMMM-YYYY (eg. 06-SEPT-2015 ) : ")
#replace space with ""
date = date.replace(" ", "")
conDate=convertDate(date,1)
print("Date in ISO 8601 representation is : "+conDate)
elif choice=="2":
date = input("Enter date in ISO 8601 format (eg 2018-12-12) : ")
#replace space with ""
date = date.replace(" ", "")
conDate=convertDate(date,2)
print("Date in business format : "+conDate)
elif choice=="3":
break
else:
print("Please enter valid choice")
  

output:
