I have a long line of code that I want to break up among multiple lines. What do I use and what is the syntax?
For example, adding a bunch of strings,
e = 'a' + 'b' + 'c' + 'd' and have it in two lines like this:
e = 'a' + 'b' + 'c' + 'd'

Use a backslash ( \ ) as a line continuation character In Python, a backslash ( \ ) is a line continuation character. If a backslash is placed at the end of a line, it is considered that the line is continued on the next line.
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 backslash character "\" is used to indicate the line continuation in Python.
What is the line? You can just have arguments on the next line without any problems:
a = dostuff(blahblah1, blahblah2, blahblah3, blahblah4, blahblah5, blahblah6, blahblah7) Otherwise you can do something like this:
if (a == True and b == False): or with explicit line break:
if a == True and \ b == False: Check the style guide for more information.
Using parentheses, your example can be written over multiple lines:
a = ('1' + '2' + '3' + '4' + '5') The same effect can be obtained using explicit line break:
a = '1' + '2' + '3' + \ '4' + '5' 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.
