The back-slashes in the script all had other purposes, and I had not realised that where they fell was significant. Backslashes may still be appropriate at times. Actually, you have the style guide's preference exactly backwards. The Python standard library is conservative and requires limiting line s to 79 character s (and docstrings/comments to 72). Python Server Side Programming Programming. You can use the resulting iterator to quickly and consistently solve common programming problems, like creating dictionaries.In this tutorial, you’ll discover the logic behind the Python zip() function and how you can use it to solve real-world problems. Following the tradition from mathematics usually results in more readable code: In Python code, it is permissible to break before or after a binary operator, as long as the convention is consistent locally. The Python standard library is conservative and requires limiting lines to 79 characters (and docstrings/comments to 72). A backslash is illegal elsewhere on a line outside a string literal. How can I do a line break (line continuation) in Python?

I have a long line of code that I want to break up among multiple lines. Ada – Lines terminate with semicolon; C# … A backslash does Long lines can be broken over multiple lines by wrapping expressions in parentheses. Argument Passing¶. This is helpful in some cases, but should usually be avoided because of its fragility: a white space added to the end of the line, after the backslash, will break the code and may have unexpected results. Make sure to indent the continued line appropriately. Line continuation is generally done as part of lexical analysis: a newline normally results in a token being added to the token stream, unless line continuation is detected. What is the line? A backslash does not continue a token except for string literals (i.e., tokens other than string literals cannot be split across physical lines using a backslash). Two or more physical lines may be something like, https://stackoverflow.com/questions/53162/how-can-i-do-a-line-break-line-continuation-in-python/53173#53173, https://stackoverflow.com/questions/53162/how-can-i-do-a-line-break-line-continuation-in-python/110882#110882, https://stackoverflow.com/questions/53162/how-can-i-do-a-line-break-line-continuation-in-python/53182#53182.

Welcome! x = (5 + 4 + 2 + 1 + 6 + 4 + 9 + 7 + 8) For example. For new code Knuth’s style is suggested. Notice also that breaking literal strings into pieces allows to use the literal prefix only on parts of the string and mix the delimiters: Taken from The Hitchhiker's Guide to Python (Line Continuation): When a logical line of code is longer than the accepted limit, you need to split it over multiple physical lines. def print_something (): print ('Look at us,', 'printing this sentence on multiple lines.') This loop iterates through every item in the list produced by os.listdir(). What Is a Line Continuation Character in Python? The line continuation character cannot be followed by any value. When known to the interpreter, the script name and additional arguments thereafter are turned into a list of strings and assigned to the argv variable in the sys module. If necessary, you can add an extra pair of parentheses around an expression, but sometimes using a backslash looks better. PEP8 did indeed change in 2010 - "sometimes using a backslash looks better" has gone. These should be used in preference to using a backslash...", and all backslashes were removed from the code example. Using parentheses, your example can be written over multiple lines: The same effect can be obtained using explicit line break: Note that the style guide says that using the implicit continuation with parentheses is preferred, but in this particular case just adding parentheses around your expression is probably the wrong way to go.
