Is it better to do:

message = """This is line1.
This is line2
This is line3\n"""

or

message = "This is line1.\n
message = message + "This is line2\n"
message = message + "This is line3\n"
Since the first method does not follow python's clean and easy looking
indentation structure but the second just looks crude and ugly anyway.

If I indent the first version so the text is lined up to match code
indentation then this comes out in the input and isn't aligned there.

Is there any reason you can't do it in one line?

message = "This is line1.\nThis is line2.\nThis is line3.\n"

How about

message = ("This is line1. "
"This is line2 "
"This is line3\n")

The brackets mean that the lines are automatically treated as
continuous, without the need for the ugly '\' continuation character.

The opening/closing quotes on each line mean that the strings are
contatenated into one long string.

Don't know what happened there - Google seems to have messed up my
indentation.

My intention was that each of the three leading quote marks line up
vertically, but when I read it back via Google Groups, the second two
lines were pushed over to the right.

Hi,

msgs = ['This is line1.','This is line2.','This is line3.']
message = '\n'.join(msgs)

Regards,

assuming fixed-pitch fonts isn't very Pythonic, though; to get reliable indentation
no matter what font you're using, you can write:

message = (
"This is line1. "
"This is line2 "
"This is line3\n")

whether this is better than """ depends on the situation.

Obvious, now that you mention it.

Thank you.

If you want indented and pretty is important to you:

from textwrap import dedent as D
message = D("""\ This is line1.
This is line2
This is line3
""") message

'This is line1.\nThis is line2\nThis is line3\n'

Usually though I would just make sure that long strings are declared at
module level and not indent them. The backslash after the opening quotes
stops the first line being indented differently:

message = """\
This is line1.
This is line2
This is line3
"""

What about

message = """
This is line 1
This is line 2
This is line 3
"""

When it is necessary to skip first empty line):
message = """
This is line 1
This is line 2
This is line 3
"""[1:]
When necessary to skip first line _and_ indentation:
message = """
This is line 1
This is line 2
This is line 3
""".replace ('\n ', '\n')[1:] # adjust here '\n ' to indentation
# ^-- gives 'This is line 1\nThis is line 2\nThis is line 3\n'

?

""".replace ("""
