. Create a list of temperatures in degrees Celsius with the values 25.2,16.8, 31.4, 23.9, 28, 22.5, and 19.6, and assign it to a variable called temps. Using one of the list methods, sort temps in ascending order. Write for loop to convert all the values from temps_in_celsius into Fahrenheit, and store the converted values in a new list temps_in_fahrenheit.

Create a class “employee” with attributes like id, name, designation, emailid, birthdate, city. a.getData() to take employee information. b.setData() to display employee information. Inherit class “Account” with attributes like acc_id, acc_type, amount and methods to generate account report of peticular employee in proper format. Implement regular expression to validate emailid and birthdate.
