Since Python treats a newline as a statement terminator, and since statements are often more then is comfortable to put in one line, many people do:
if foo.bar()['first'][0] == baz.quux(1, 2)[5:9] and \
calculate_number(10, 20) != forbulate(500, 360):
pass
You should realize that this is dangerous: a stray space after [...]

On the Modules page of the Python docs, there is this code example:
def fib(n): # write Fibonacci series up to n
a, b = 0, 1
while b < n:
print b,
a, b = b, a+b
Being new to Python, this code snippet confused [...]

Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the [...]
