plz answer these short ans in python language

Q1- Write an expression whose value is the str that consists of the second through fifth characters of the str associated with s.

Q2-Given that s refers to a string, write an expression that evaluates to a string that is a substring of s and that consists of all the characters of s from its start through its ninth character.

Q3- 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 first three characters of the value of word. So if the value of word were "dystopia" the expression's value would be "dys".

Q4-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".
