While the general mechanism for continuation of a source line on the next physical line remains to place a backslash on the end of the line, expressions inside matched parentheses (or square brackets, or curly braces) can now also be continued without using a backslash. This is particularly useful for calls to functions with many arguments, and for initializations of large tables.
For example:
month_names = ['Januari', 'Februari', 'Maart', 'April', 'Mei', 'Juni', 'Juli', 'Augustus', 'September', 'Oktober', 'November', 'December']
