Python打印语句“语法错误：无效语法”

为什么Python在第9行的简单print语句中给我一个语法错误？

 import hashlib, sys m = hashlib.md5() hash = "" hash_file = raw_input("What is the file name in which the hash resides? ") wordlist = raw_input("What is your wordlist? (Enter the file name) ") try: hashdocument = open(hash_file,"r") except IOError: print "Invalid file." # Syntax error: invalid syntax raw_input() sys.exit() else: hash = hashdocument.readline() hash = hash.replace("\n","") 

Python的版本是：

 Python 3.2.2 (default, Sep 4 2011, 09:07:29) [MSC v.1500 64 bit (AMD64)] on win 32 

Answer 1

在Python 3中，print是一个函数，你需要把它叫做print("hello world") 。

Answer 2

使用print("use this bracket -sample text")

在Python 3中print "Hello world"会导致无效的语法错误。

要在Python3中显示string内容，必须使用这个("Hello world")括号。
