Hello,
I am new to python, but i am quite curious about the following.
suppose you had
print '\378'
which should not work because \377 is the max. then it displays two
characters (an 8 and a heart in my case...). What else does'nt quite
make sense is that if this is an octal why is an 8 accepted?
for instance is 378 really 11, 111, 1000 which is then the two
characters: <00000001>,<111 1000>. And why is this accepted?
I apologize if this has been discussed or if it is obvious. I would
appreciate it if someone could clear me up.
Yours,
PD 4 1882

Because 8 isn't an octal digit, so it's not part of the escape
sequence, but a separate character. It's just like
print 'This string\47s escape sequence does not include the s.'
Your example displays two characters because it is two characters:
'\037' and '8'.

It's not doing quite what you think. The '\37' is seen as octal, but
since '8' isn't a valid octal digit, it's seen as the literal character '8'.
In other words, these two lines are equivalent: '\378'
'\x1f8' '\37' + '8'
'\x1f8'
'\378' becomes a two character string. The first character is '\37'
and the second character is '8'. str = '\378' str[0]
'\x1f' str[1]
'8'

It would appear that the parser reads \377 as a single character and
\378 as two (\37 and the "8" character). I'm somewhat surprised you're
seeing a heart and an 8. What OS/language combination are you using?
If you're using English Windows you can get a heart and an "8" with
"print '\38'".

I have an XML file that I want to read in and pass as a string to a

I am using a TextReader to read the file in, but my string that I end

How do I get a string from my file that doesn't have all these extra

Something like:

The string s below has single and double qoutes in it. For testing I
surrounded it with triple single quotes. I want to split off the
portion before the first \, but my split that works with shorter
strings does not seem to work with this one.
Ideas?
Thanks,

Converting a string variable into a string literal. How do I add the

I cannot add it when the string is created as it will affect other
parts of the program.
I have tried these but they do not work:
label1.text = @S
label1.text = "@" + S
