Answer 1

Lets assume you have a list of lines from your file stored in items

>>> items = ['a', 'b', 'c', 'd', 'e', 'f']
>>> choices = random.sample(items, 2)  # select 2 items
>>> choices  # here are the two
['b', 'c']
>>> for i in choices:
...   items.remove(i)
...
>>> items  # tee daa, no more b or c
['a', 'd', 'e', 'f']

From here you would overwrite your previous text file with the contents of items joining with your preferred line ending \r\n or \n. readlines() does not strip line endings so if you use that method, you do not need to add your own line endings.
