# basic way to print out a file:

>>> file = open('readme.txt','r')
>>> print file.read()



# prints out each character of a file followed by a new line:

>>> file = open('readme.txt')
>>> while 1:
...     char = file.read(1)
...     if not char: break
...     print char


# same thing with less lines:

>>> for char in open('readme.txt').read():
...     print char


# prints lines of a file:

>>> file = open('readme.txt')
>>> while 1:
...     line = file.readline()
...     if not line: break
...     print line


# same thing, less code:

>>> for line in open('readme.txt').readlines():
...     print line

>>> for x in open('readme.txt').xreadlines():
...     print x
