Reading a text file

[DeaD_EyE]

Just as a joke, but you can still learn about this.
Don't use this code.

with open(file_name) as fd:
    lineiterator = iter(fd)
    for line in lineiterator:
        print(line.strip())
        with contextlib.suppress(StopIteration):
            next(lineiterator)

fd is the file object.

The function iter(fd) makes an iterator from the file object.
This works only, when the file has been opened in text mode. Calling iter on a file object,
does the same what the for-loop does. The call next(lineiterator) jumps to the next line.
As you can see, there is no use of the returned data of next(lineiterator).
contextlib.suppress is just a context manager to suppress errors. In this case
StopIteration is suppressed. If this Exception StopIteration happend,
the end of file has been reached. The for-loop does get this Exception also and stops silently.
