So Python needs a way to express that you *explicitly* mean "this is
one of those rare one-element tuples, not an order of operations
prioritization":
(1,) + (2,)
to return "(1,2)"
Yes i can see the difference now!! I just had to look at the big picture
here! There is no other way of seperating this for that.
You can also prefix any of them with "r" such as
file_path = r"c:\path\to\file.txt"
file_path = r'c:\path\to\file.txt
file_path = r"""c:\path\to\file.txt"""
file_path = r'''c:\path\to\file.txt'''
'r' is to avoid escaping backslashes only or other special charcaters as
well?
As for the string i noticed that if i'am to mix single quotes and double
quotes(any number of them not just always pairs)
and backslashes and other special stuff in them then i'm best off using
3-sinlge-quotes like
name='''My name is "Nikos" and i'am from Thessaloniki\Greece'''
The above example can only be written by using 3-single quoting right?
Not by pairs of single or double quotes, correct?
And i dont have to use the 'r' in fornt of it too.
=======================
Also if you please comment on my mysql string substitution example i've
posted in my previous post just to make it work.
I want it to be able to delete my data but it fails when i try to
http://webville.gr/index.html?page="100 ; DELETE FROM visitors; SELECT *
FROM visitors"
<http://webville.gr/index.html?page=%22100%20;%20DELETE%20FROM%20visitors;%20SELECT%20*%20FROM%20visitors%22>
please try it yourself, i dont mind lossign the data i just want to see
if this mysql in jection can actually work.
Thank you.
