Display the last part of a file (unix tail)
Level: Beginner (score: 2)
Complete the function below simulating Unix' tail, for example:
$ tail -3 test_tail.py
# byte to str conversion and strip off last line's newline char
expected = [line.decode("utf-8") for line in lines]
assert tail(f.name, 10) == expected
Complete the function below which receives (absolute) filepath and n lines to filter from the end which is returned in a list.
For example, if we call it on a file - stored in filepath - with this content:
Hello world! We hope that you are learning a lot of Python. Have fun with our Bites of Py. Keep calm and code in Python! Become a PyBites ninja!
... and give it n of 2 (= calling it as: tail(filepath, 2)), it should return this:
['Keep calm and code in Python!', 'Become a PyBites ninja!']
(note: newlines are stripped off)
Have fun and let us know if you have any questions ...
