[Tutor] end of file symbol?

[Kent Johnson]

Jeff,

end-of-line is platform-dependent. On Unix / Linux / Mac OSX it is \n. On 
Windows it is usually \r\n. On MacOS 9 it is \r.

If you open a file with the mode 'U' or 'rU' you get "universal newline 
support" which converts any of these newline types to \n. (See 
http://docs.python.org/whatsnew/node7.html)

If you are processing text line-by-line, there might be a better way to do 
it than searching for \n. You can read a file by lines like this:
f = open('myfile.txt', 'rU')
for line in f:
     # do something with line

If you have the text in a string already you can use
for line in s.splitlines():
     # do something with line

or just
lines = s.splitlines()
to get a list of all the lines.


There is no end-of-file character, you just run out of data.
