Is it possible to print a block of embedded text in python?
In perl you can do it like this this:
Not sure I am following. Can you give a more concrete example with input/output? I just don''t get exactly what you are trying to do.
In python you can do:
TestVar = 5
print ''Value is '' + str(TestVar) + '' do da do dah''
or:
print (''Value is %d do da do dah'') % (TestVar)
What is it that you are trying to do?

If I want to output a piece of html from my script without getting it from some external source, but instead have it embedded in my script I want to avoid having to quote every line of html.
I could do:
print 'html..'
print 'html..'
...
In perl I can do:
print <<EOF;
html..
html..
...
EOF
Quite nice, because then you can just copy and paste the html there without having to print and quote every line.

You can''t do that in Python. Perl evolved from the position of string processing first into a full programming language, so its string processing capabilities are exceptionally strong. PHP can also do the block text thing. In Python you''d need to do a couple of things, given that it''s print functionality is more C-like:
# Python:print ''some text '', var, '' and more text.\n''print ''text that starts on one line...\n'' \ ''requires a continuation character...\n'' \ ''and an explicit newline for the ouput to break.''
Uhm, no.
The """ is the trick.
(the example above assumes that var is a local variable. If not, use %s and an ordered sequence(tuple, list) instead.)

Well, I tried it but got a little dissapointed.
Apparently when doing formatting, some characters become
invalid. Those include " > < and obviously those are
important in html. So what I had to do is copy and paste
the html and then, where I would have formatting variables,
instead write something like !var1!. Then do a search replace
and print:
s = """<tag>
<tag2 = "!var1!">
<tag3 = "!var2!">
</tag>"""
print s.replace('!var1!',var1).replace('!var2!',var2)
Oh well...

Uh, what are you talking about? The following works perfectly for me:

I got errors that were telling me that thoe characters were invalid, but I guess someinth else caused it. The percent character is however causing problems, so I have to change
all % as %%.
I''m getting sloppy.. No, wait.. I''ve always been sloppy..
all % as %%.

Uhm, no.
