[Tutor] Why different behaviours?

[Danny Kohn]

Hi.

Why does:
import string, sys
f=3Dopen('d:/Dokument/Programprojekt/pythonworks/projects/H2/Lexicon.txt'=
, 'r')
line =3D f.readline()
print line

and:

import string, sys
f=3Dopen('d:/Dokument/Programprojekt/pythonworks/projects/H2/Lexicon.txt'=
, 'r')
for line in f.readline():
	print line

does not give the same result?

Also, what would be the way to read line after line until end of file. =
How to detect end of file when reading a sequential file this way?
