Practical difference between keyword "print" and function "print" in Python [duplicate]

Question

For Python2x If we use,

from __future__ import print_function

the print will become function which is previously the keyword

But practically,

How two of these are different ?

I can still use print the same way as I was using it when it was a keyword, then what difference does it make and how could it be more efficient than before ?

Answer 1

Here you can read some official documentation with examples and PEP3105 with more details.

As quick differences, there are several things which are very easy to do with print function (Python 3 or from __future__ import print_function) or at least very consistently:

No newline

print('Hello!', end='')

That was more complicated in python 2.

Print to stderr

import sys
print('ERROR!!!!!', file=sys.stderr)

In python 2.
