SyntaxError: Missing parentheses in call to 'print'. Did you mean print('hello,

python world';)?

 

 

其实这个错误信息，是因为Python3中取消了以前Python 2中的语法，两者在打印输出的语法上有所差别，所以在Python 3下面使用之前的语法格式就会报错，错误信息已经提示你需要加上括号，字符串可以用单引号或双引号括起来，正确语法格式如下所示：

 

C:\Users\konglb>python -V

Python 3.6.3

>>> print ('hello,python world')

hello,python world

>>> print("you are right")

you are right

>>>
