No, this is not true. You are describing implicit line joining, which
is described in the Library Reference[1] Section 2.1.3[2].
"Expressions in parentheses, square brackets or curly braces can
be split over more than one physical line without using
backslashes... The indentation of the continuation lines is not
important. Blank continuation lines are allowed."
Besides, you don't NEED ';' in Python to end a single statement.

You can combine statements (Compound Statements[3]) on a single line
with the ';' character...
print 'ERROR: You are mistaken'; sys.exit(1)
Or control flow constructs...
if test: if test2: print x
Which could just as easily be written
if test:
if test2:
print x

yay.
