shoes object with this data and append this object into the
shoes list. One line in this file represents data to create one
object of shoes. You must use the try-except in this function
for error handling. Remember to skip the first line using your
code.
capture_shoes - This function will allow a user to capture
data about a shoe and use this data to create a shoe object
and append this object inside the shoe list.
view_all - This function will iterate over the shoes list and
print the details of the shoes returned from the _str_
function. Optional: you can organise your data in a table
format by using Python's tabulate module.
re_stock - This function will find the shoe object with the
lowest quantity, which are the shoes that need to be
re-stocked. Ask the user if they want to add this quantity of
shoes and then update it. This quantity should be updated
on the file for this shoe.
seach_shoe - This function will search for a shoe from the list
using the shoe code and return this object so that it will be
printed.
value_per_item - This function will calculate the total value
for each item. Please keep the formula for value in mind;
value = cost * quantity. Print this information on the console
for all the shoes.
highest_qty - Write code to determine the product with the
highest quantity and print this shoe as being for sale.
O Now in your main create a menu that executes each function
above. This menu should be inside the while loop. Be creative!

get_cost - Returns the cost of the shoes.
get_quantity - Returns the quantity of the shoes.
_str_ - This method returns a string representation of a

Outside this class create a variable with an empty list. This variable
will be used to store a list of shoes objects
Then you must define the following functions outside the class:
