Python 3 (not java)

1.Assume that word is a variable of type String that has been assigned a value. Write an expression whose value is a String consisting of the last three characters of the value of word. So if the value of word were "biggest" the expression's value would be "est".

2.Given three String variables that have been given values, firstName, middleName, and lastName, write an expression whose value is the initials of the three names: the first letter of each, joined together. So if firstName, middleName, and lastName, had the values "John", "Fitzgerald", and "Kennedy", the expression's value would be JFK". Alternatively, if firstName, middleName, and lastName, had the values "Franklin", "Delano", and "Roosevelt", the expression's value would be "FDR".

3.Write an expression that evaluates to True if and only if the variables profits and losses are exactly equal.
