Hot to split string literals that will across two or more lines ?

[Xiao Jianfeng]

Hi,

I need to print a long sting, which is two long so it must expand two
lines.
I know that we can use backslash(\) to explicitly join two lines into a
logical line,
but this doesn't work for string literals :(

my code:
-----------------------------------------------------------------------------
if sth.:
print "a string whcih is very very loooooooooooooo ooooooooooooooo oooooo\
ooooooooooooooo ooooong."
-----------------------------------------------------------------------------

If I don't break the line, it will be very ugly, if I break the
line,....but how ?

Thanks in advance!

You can leave out the "+" if you want, adjacent strings are
automatically
concatenated.

print "a string which is very loooooo" \
"ooooong."

Perhaps this is more efficient, since the string concatenation can be
done by Python's parser rather than at runtime?

print "a string which is very loooooo" \
+ "ooooong."

Thanks for catching that...I haven't been working with Python as much as
I was a year or so ago and I'm forgetting some of the details.

How is this string being constructed in the source? If it exists as a
single long string, why must it be so long?

Some techniques you may not be aware of:

chunks = ["abc", "def", "ghi"]
s = ''.join(chunks)
print s abcdefghi
s = "#" * 10
print s

##########

You can, of course, modify the above so that they join or multiply to
create much longer strings.

Minor pedantry, but the plus sign is redundant. Python automatically
concatenates string literals on the same logical line separated by only
whitespace.

While we're at it, I use bracketing instead of line continuation:

print ( "a long string, longer than this "
"and some more of the string" )

To continue the pedantry: Those are parentheses, not brackets.

Slightly more on-topic, the parentheses make it look like a sequence
to this reader (though, without a comma, not to the Python parser, of
course).
