I don't really follow what you mean since I've never used ABAP, but
here's how I typically read a file in Python:

f = open("someFile.txt")
for line in f:
    # do something with the line
    print line
f.close()

Of course, you can read just portions of the file too, using something
like this:

f.read(64)

Which will read 64 bytes. For more info, check the following out:
