Instructions

Open the starter file and perform the following:

Create string variables.

Create a variable named subject with no value (i.e. set the value to None).
Assign a value of “Programmers” to the variable subject.
Create a variable, first_name, and assign it a value of an empty string.
Assign a value of “Ada” to the variable first_name.
Create a variable, last_name, and assign it a value of a string, “Lovelace”.
Create a variable, full_name, and assign it a value of the combination of first_name and last_name with a space.
Create a variable, profession, and assign it a value of a string, “Computer Programmer”.
Create a variable, known_for, and assign it a value of a string, “First Computer Programmer”.
Create a variable, first_algorithm, and assign it a value of a string, “Analytical Engine”.
Create a variable, city_location, and assign it a value of a string, “London”.
Create a variable, country_location, and assign it a value of a string, “England”.
Create a variable, nationality, and assign it a value of a string, “British”.

Create integer variables.

Create a variable, birth_year, and assign it with an integer of 1815.
Create a variable, death_year, and assign it with an integer of 1852.
Create a variable, age_at_passing, and assign it a value of death_year minus birth_year.
Create a variable, year_of_publish, and assign it with an integer of 1842.

Print the variables.

Print: “First Name: ” and first_name.
Print: “Last Name: ” and last_name.
Print: “Profession: ” and profession.
Print: “BirthYear: ” and birth_year.

Concatenate and print variables.

Create and print a variable, statement_one, by assigning it a value of a concatenated string: “Programmers: Ada Lovelace is a British Computer Programmer born in 1815.”
Create and print a variable, statement_two, by assigning it a value of a concatenated string: “She is commonly referred to as the First Computer Programmer.”
Create and print a variable, statement_three, by assigning it a value of a concatenated string: “In 1842 she published the first Algorithm, the Analytical Engine, at the age of 27.”
Create and print a variable, statement_four, by assigning it a value of a concatenated string: “She was a British Citizen who lived in London, England until her passing in 1852 at the age of 37.”
