There is more than one way to do it   1   A long statement    gt  gt  gt  def print something             print  This is a really long line                      but we can make it across multiple lines     2   Using parenthesis    gt  gt  gt  def print something            print   Wow  this also works                    I never knew      3   Using   again    gt  gt  gt  x   10  gt  gt  gt  if x    10 or x  gt  0 or          x  lt  100         print  True    Quoting PEP8      The preferred way of wrapping long   lines is by using Python s implied   line continuation inside parentheses  brackets and braces   If necessary    you can add an extra pair of parentheses around an expression  but   sometimes using a backslash looks better   Make sure to indent the continued line   appropriately  The preferred place to break around a binary   operator is after the operator  not before it

If you want to assign a long str to variable  you can do it as below   net weights pathname           home acgtyrant BigDatas        model configs lenet iter 10000 caffemodel     Do not add any comma  or you will get a tuple which contains many strs

DB related code looks easier on the eyes in multiple lines  enclosed by a pair of triple quotes   SQL      SELECT             id               fld 1               fld 2               fld 3                                FROM some tbl      than the following one giant long line   SQL    SELECT id  fld 1  fld 2  fld 3                                       FROM some tbl

When trying to enter continuous text  say  a query  do not put commas at the end of the line or you will get a list of strings instead of one long string   queryText   SELECT   FROM TABLE1 AS T1    JOIN TABLE2 AS T2 ON T1 SOMETHING   T2 SOMETHING    JOIN TABLE3 AS T3 ON T3 SOMETHING   T2 SOMETHING    WHERE SOMETHING BETWEEN  lt WHATEVER gt  AND  lt WHATEVER ELSE gt     ORDER BY WHATEVERS DESC    kinda like that   There is a comment like this from acgtyrant  sorry  didn t see that

As far as I know  it can be done  Python has implicit line continuation  inside parentheses  brackets  and strings  for triple-quoted strings     like this    and the indentation of continuation lines is not important  For more info  you may want to read this article on lexical analysis  from python org

From PEP 8 - Style Guide for Python Code      The preferred way of wrapping long lines is by using Python s implied line   continuation inside parentheses  brackets and braces   If necessary  you   can add an extra pair of parentheses around an expression  but sometimes   using a backslash looks better   Make sure to indent the continued line   appropriately      Example of implicit line continuation   a   some function       1     2     3  -  4     On the topic of line-breaks around a binary operator  it goes on to say -     For decades the recommended style was to break after binary operators    But this can hurt readability in two ways  the operators tend to get scattered across different columns on the screen  and each operator is moved away from its operand and onto the previous line       In Python code  it is permissible to break before or after a binary operator  as long as the convention is consistent locally  For new code Knuth s style  line breaks before the operator  is suggested    Example of explicit line continuation   a    1             2           3        -  4
