Does python actually disallow newlines in string literals? That is
x = 'foo
bar'
Whether you think this is good style is not the question --- is it
allowed by the language?
You can with triple-quoting and by escaping it with backslash.
The following code, admitedly ugly, is valid python:
a = 'a\
bc'
print a
b = '''a
bc'''
print b
and produces:
abc
a
bc
as output. \<newline> in any non raw literal is allowed and ignored,
while a bare <newline> in a triple-quoted string literal is allowed
and retained.
Moreover, this is not an execise of bad style only. It's customary to
write docstrings as multiline triple-quoted string literals:
def afunction(a, b, c):
"""This is a function.
Its arguments are:
a - first argument
b - second argument
c - third argument.
It does ans returns nothing.
"""
pass
It's more or less the recommended way to document a function (or class
or module or whatever). See PEP 257 for more examples:
http://www.python.org/peps/pep-0257.html
So, to answer to your question, newlines are more than allowed in
string literals.
