Define a function sum_file that consumes a string representing a filename and returns a number. this number will represent the sum of all the numbers in the given file. assume that all files will have each number on their own line. note: your function will be unit tested against multiple arguments. it is not enough to get the right output for your own test cases, you will need to be able to handle any valid filename. you can safely assume that the file will be a non-empty sequence of numbers, each on their own new line. note: you cannot simply print out a literal value. you must use a looping pattern to calculate for any file like this. note: you cannot embed the text of the file directly in your program. use the appropriate file handling style to access the data in the file.
