After adding the sentence from _ _ future__ import print_function at the beginning, even in python2.X, you have to use print in parentheses like python3.X. Parentheses are not required for print in python2.X, but are needed in python3.X.

# python2.7

Print "Hello world"

# python3

Print ("Hello world")

If a new feature appears in a version, and it is not compatible with the one used in the current version, that is, it is not a language standard in that version, then I need to import it from the future module if I want to use it.

Other examples:

From _ _ future__ import division

From _ _ future__ import absolute_import

From _ _ future__ import with_statement . Wait

Plus these, if your version of python is python2.X, you have to use these functions as python3.X does.
