在本节中，我们将检查在两个不同的python版本中打印单变量和多变量输出。
>>> #Python 2.7
>>> #Print single variable
>>> print 27
27
>>> print "Rahul"
Rahul
>>> #Print single variable, single brackets
>>> print(27)
27
>>> print("Rahul")
Rahul>>> #Python 3.6 >>> #Print single variable without brackets >>> print 27 SyntaxError: Missing parentheses in call to 'print' >>> print "Rahul" SyntaxError: Missing parentheses in call to 'print'
上面3.6中的语法，是由于：在python 3.x中，print不是语句，而是函数（print()）。因此，将print更改为print()。
>>> print (27)
27
>>> print("Rahul")
RahulPython 2.x（例如：python 2.7）
>>> #Python 2.7
>>> #Print multiple variables
>>> print 27, 54, 81
27 54 81
>>> #Print multiple variables inside brackets
>>> print (27, 54, 81)
(27, 54, 81)
>>> #With () brackets, above is treating it as a tuple, and hence generating the
>>> #tuple of 3 variables
>>> print ("Rahul", "Raj", "Rajesh")
('Rahul', 'Raj', 'Rajesh')
>>>因此，从上面的输出中，我们可以在python 2.x中看到，在方括号()中传递多个变量，会将其视为多个项目的元组
#Python 3.6
#Print multiple variables
>>> print(27, 54, 81)
27 54 81
>>> print ("Rahul", "Raj", "Rajesh")
