It can be written as a non-3-quote string, you just have to escape the
inner quotes (single & double) and the backslash to be seen:
name = 'My name is "Nikos" and I\'m from Thessaloniki\\Greece'
name = "My name is \"Nikos\" and I'm from Thessaloniki\\Greece"
So if i enclose the string in double quotes the inner double quotes have
to be escaped while
if i enclose the string in single quotes the inner single quotes have to
be escaped.
But in 3-single-quoting thing became easier since i don't have to escape
all kind of quotes right? just the backslashes.
And i dont have to use the 'r' in fornt of it too.
Using the 'r' in front would make it much more challenging, because it
would prevent the backslashes from being seen as escaping. :)
So the best way to write the above assignment statement would be:
name = r'''My name is "Nikos" and I'm from Thessaloniki\Greece'''
It cannot get any easier that that can it? :)
''' ''' helps avoid escaping all kind of quotes!
'r' avoid escaping backslashes!
=============================
Why does the page variable which is actually a string needs to be a
tuple or a list and not just as a string which is what it actually is?
I have a strong desire to use it like this:
cursor.execute( '''SELECT hits FROM counters WHERE page = %s''' , page )
opposed to tuple. Would i might facing a problem? Of what? MySQLdb
instead of give the whole value to the placeholder to give just a single
char?
Also do i need 3-single-quoting here as well or it can be written qith
signle/double quotes?
What appleis to strings apply to mysql queries as well?
