apply all the concepts you learned in previous weeks and apply the use of sequential input and output operations to add two new functionalities to your Employee Management System.

• Export employees' information to text file: This functionality will allow the user to save the employee information saved in the list to the file system. Each list entry should be saved into a new line. You may notice by now that closing the script will cost your Employee Management System to lose all entered employees' information. Exporting the current system data into a file system will help you to save this information permanently on the hard disk and be able to use it at later time.
• Import employees' information from text file: This functionality will help you to import preexisting employee information from a text file saved on the file system. Each line in the text should be saved as a new list entry. When you run your Employee Management System for the first time you should be able to populate the system with preexisting employee information, if there are any, instead of adding this information manually to the system.

Here is my script, I keep getting an error the top part is what I just added the rest of the code works without it.

mployees = []

count = 0

f = open("employeedata.txt", "w")

for i in employees:

f.write(i[0]+" "+str(i[1])+" "+str(i[2])+" "+str(i[3])+" "+str(i[4])+" ")#write each employee data to file

f.close()

# method that imports data from file to list

file = open("employees.txt", "r")

l = list(file.readiness())

for i in range(len(l)):

l[i] = l[i][:-1]

for i in l:

t = i.split("") # stores each employee data to list

employees.append(t)
