Angela wrote some lines of code that she wants to test. She will need to use a python interpreter. IDLE open source a prompt a file path
A python interpreter helps a programmer to debug his/her codes line by line i.e to check if there are any error present in the code for necessary adjustment. Codes cannot be understood ordinarily by computer because they are are machine languages hence the reason why python interpreter is needed to translate the line of codes of the programming language.
Note that python interpreter will be used to interpret the lines of code due to the learning environment/filepath used which is IDLE.
