When i open a file in python, and then print the

Try
print(line.rstrip())
Your 'line' text value must still have line endings in it. .rstrip()
will remove trailing whitespace on the right. print() will then do its
own line ending.
Answer I don't know: why are the line endings still in the text values?

Because they are in the file.
Iterating over the file yields a line at a time (like file.readline()).
All but the last line will have a line ending; the last line may.
You might want to know what is actually in the file, including whether
the last line has a line ending or not, so you don't always want to
drop it, if present.
