INST326-Exercise People Solved

 You will be writing three functions (parsename, parseaddress, parse_email) that use regular expressions to extract data from the string that we pass into the functions. You will also write two classes that will act as data containers. These classes are address and employee.

 The address class will have 3 attributes, street, city and state. The employee class will have four attributes, firstname, lastname, address, and email. Your script should also contain a main function that will have one parameter, a path to the file that we are extracting data from. Your main should read the file and will create employee instances out of each row in the file.

 Note
 The name of your file should be people.py
This exercise does not require the use of command line arguments.
 Instructions
 Download the people.txt file and place it within the same cwd as your python script.
Your script should import the "re" module.
Your script should define the function parse_name.
This function will contain one parameter, text, a string representing a single line of the file.
This function should use regular expressions in order to capture the first name and last name of the person in question.
This function will return a tuple containing the first and last name as strings.
Your script should define the function parse_address.
This function will contain one parameter, text, a string representing a single line of the file.
This function should use regular expressions in order to capture the street, city and state of the person in question.
This function will create and return an address object using the street, city and state identified.
Your script should define the function parse_email.
This function will contain one parameter, text, a string representing a single line of the file.
This function should use regular expressions in order to capture the email of the person in question.
This function will return the email identified.
Write a class Address
This class will have 3 attributes (street, city, state) that are created from the arguments that are passed in when an instance of address is created.
This class will not have any methods.
Write a class Employee
This class will have 4 attributes (firstname, lastname, address, email).These attributes will all be created by passing in a row of the file when an instance of employee is created. This meaning, the init method will only have one parameter other than self.
The firstname and lastname attributes are created by calling the parsename function and passing in the parameter of the init method of employee as an argument in the parsename function call.
The address attribute is created by calling the parseaddress function and passing in the parameter of the init method of employee as an argument in the parseaddress function call.
The email attribute is created by calling the parseemail function and passing in the parameter of the init method of employee as an argument in the parseemail function call.
This class will not have any methods.
Write a main function. Your main should have one parameter, path, which is the path to the file that is being parsed.
Create an empty list called employee_list.
Open up the file from the path.For each line in the file, create an instance of employee by passing in the string which is the line of the file that you are reading.
Append this instance to the employee_list.
Within the main, return the employee_list
Write an if name == main statement
Call the main using the "people.txt" file, save the returned value.
Print this returned value.
 Hints
 You will notice that the text file is formatted in a particular way. Use this formatting to your advantage when writing the regular expressions.
You will notice that as you iterate over the lines in the file, that you are in essence breaking up the strings that you are working on to be just the single lines, meaning, you might find it advantageous to use anchors (^ or $) when writing regular expressions to indicate that you are matching items at the beginning or ends of the stings.
