The most common operations:

file_object = file('somefile.txt', 'r')  # 'r' for read, 'w' for write
file_object = open('somefile.txt', 'r')  # In Python 2.1 or earlier
buf = file_object.read()  # Slurp the whole file at once. OR...
lines = file_object.readlines()  # Split whole file into lines. OR...
for line in file_object.xreadlines():  # Only one line at a time. OR...
    do_something_with(line)
for line in file:  # Same as above, Python 2.2 and greater
    do_something_with(line)
