File Exercise

Goal

Get a little bit of practice with handling files and parsing simple text.

Paths and File Processing

Write a program which prints the full path for all files in the current directory, one per line. Use either the os module or pathlib.

Write a program which copies a file from a source, to a destination without using shutil, or the OS copy command. You are essentially writing a simple version of the OS copy command.

• This should work for any kind of file, so you need to open the files in binary mode: open(filename, 'rb') or 'wb' for writing. Note that for binary files you can’t use readline(). Lines don’t have any meaning for binary files.

• Test it with both text and binary files. Maybe a jpeg or something of your choosing.

• Advanced: make it work for any size file: i.e. don’t read the entire contents of the file into memory at once.

• This should only be a few lines of code.
