For some reason I took the impression that you could split expressions
over lines. However, this works:
word = 'spam'
new_word = word + 'eggs'
print(word)
But this is a syntax error:
word = 'spam'
new_word = word +
'eggs'
print(word)
That's easy to avoid, but what if you're adding five or six very long
things, like some really long strings?
Simplest thing is to add parentheses around the expression.
new_word = (word + 'a very long string' + other_word +
"another long string" + still_another)
Alternatively, you can also use the statement continuation mechanism,
whereby the last character of the line is a backslash. Using that
approach you can break almost anywhere, except within a token or inside
a string literal. And you can break up string literals without using a
"+" operator, because adjacent string literals are combined at compile time.
a = "this" \
" string" " is long"
is exactly equivalent to
a = "this string is long"
