Python, are you ill?

[wxPythoner]

If you are in the interactive prompt of the Python interpreter and you
do this

print """Testing\""" or print '''Testing\'''

you get three dots [...] as if Python expects a code block. If you
press Enter, you get three dots again, and again, and again... You
can't get out of the code block with pressing the Enter key; you have
to press Ctrl+Z (if you're in Linux) in order to get out of that code
block, which then throws you back to the Linux command line, but
before that it prints this line

[1]+ Stopped python


If you do

print "Testing\" or print 'Testing\'

you get an error, but not of you use the triple quotes. Is that a bug
in the interpreter perhaps?

No. This might clue you in:

you get three dots [...] as if Python expects a code block. If you

That is because Python expects you to end the triple-quoted string with
three unescaped quotes.

you have to press Ctrl+Z (if you're in Linux) in order to get out of that code
block, which then throws you back to the Linux command line, but
before that it prints this line

That ^Z just suspends your Python interpreter. It has become a job you can
now bring to foreground again with "fg". (but it's a feature of your
shell, not of Python)

If you do

print "Testing\" or print 'Testing\'

you get an error, but not of you use the triple quotes. Is that a bug
in the interpreter perhaps?

The fact is, that triple-quoted strings can span on multiple lines, and
that single-quoted strings cannot (without the line ending with a "\").
So no, it's not a bug in the interpreter.

You can use Ctrl+C and Python will stop what it's doing and go back to
its main prompt.

No, you don't. You can also enter """ or ''' to properly close the quote.

If you do

print "Testing\" or print 'Testing\'

you get an error, but not of you use the triple quotes. Is that a bug
in the interpreter perhaps?

As a general rule, when you are just beginning to learn some product, it is
safe to assume that anything you see as a bug in the product is almost
certainly a flaw in your understanding of the product.

I hold further, it is more profitable, unless you can change it.
