I have the above-mentioned error in s1="some very long string............"
Does anyone know what I am doing wrong?
(Assuming you don't have/want line breaks in your string...)
How long is this string really?
I suspect there is a limit to how long a line read from a file or from the commandline can be, and because the end of the line gets choped off the parser sees something like s1="some very long string..........
(without an ending "
) and thus throws a parsing error?
You can split long lines up in multiple lines by escaping linebreaks in your source like this:
s1="some very long string.....\
...\
...."
I also had this exact error message, for me the problem was fixed by adding an " \"
It turns out that my long string, broken into about eight lines with " \" at the very end, was missing a " \" on one line.
Python IDLE didn't specify a line number that this error was on, but it red-highlighted a totally correct variable assignment statement, throwing me off. The actual misshapen string statement (multiple lines long with " \") was adjacent to the statement being highlighted. Maybe this will help someone else.
In my case with Mac OS X, I had the following statement:
model.export_srcpkg(platform, toolchain, 'mymodel_pkg.zip', 'mymodel.dylib’)
I was getting the error:
File "<stdin>", line 1
model.export_srcpkg(platform, toolchain, 'mymodel_pkg.zip', 'mymodel.dylib’)
^
SyntaxError: EOL while scanning string literal
After I change to:
model.export_srcpkg(platform, toolchain, "mymodel_pkg.zip", "mymodel.dylib")
It worked...

All code below was tested with Python 3.8.3
Simplest -- just use triple quotes.
Either single:
long_string = '''some
very
long
string
............'''
or double:
long_string = """some
very
long
string
............"""
Note: triple quoted strings retain indentation, it means that
long_string = """some
very
long
string
............"""
and
long_string = """some
very
long
string
............"""
or even just
long_string = """
some
very
long
string
............"""
are not the same.
There is a textwrap.dedent
function in standard library to deal with this, though working with it is out of question's scope.
You can, as well, use \n
inside a string, residing on single line:
long_string = "some \nvery \nlong \nstring \n............"
Also, if you don't need any linefeeds (i.e. newlines) in your string, you can use \
inside regular string:
long_string = "some \
very \
long \
string \
............"
