<s>[INST] Is it possible to break a long line to multiple lines in Python Just like C, you can break a long line into multiple short lines. But in Python, if I do this, there will be an indent error... Is it possible?
 [/INST] 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.  The preferred place to break around a binary operator is
  after the operator, not before it.

Example of implicit line continuation:
a = some_function(
    '1' + '2' + '3' + '4')

Example of explicit line continuation:
a = '1' + '2' + \
    '3' + '4'
