python - Closest approximation to Python 2 style printing in python 3

Question

What are options for keeping as close to the python2 way of printing.

>>> x1='hi'
>>> x2='there'
>>> print "Val1=%s Val2=%s" %(x1,x2)
  File "<stdin>", line 1
    print "%s" %x
             ^
SyntaxError: invalid syntax

It would not be necessary to mention : "lose your 'old' way of thinking and use the {} in python3." I am aware of the "blessed" python3 syntax, and given it is not in my estimation preferable, would like to see what other options exist.

thanks.

Answer 1

这在 python 3 中仍然是有效的语法，但print 不再是 statement。它是一个函数，所以你必须放括号：

print("%s" % x) 

Answer 2

没有任何。如果您想要完美的兼容性，请避免print/完全。print()

sys.stdout.write('%s\n' % (x,))
