您在评论中没有缩进。

注意：评论是"""和不是"

import HTML 
def CreateEvent(str):
    """This prints a passed string into this function"""
    #^ Indentation space needed here - Also docstrings are represented with """ and not "
    print str
    #Good practice to have 4 spaces as indentation.
    return
    #     ^ No need of ;

一个好主意是安装pep8python 库并执行

pep8 <filename>.py

并解决问题（如果有）

您需要正确缩进：

def CreateEvent(str):
    "This prints a passed string into this function"
    ...

...根据 PEP8，这应该是一个三引号字符串

...并且不要在行尾放置分号

错误消息的名称应该让您了解问题所在。

您没有正确缩进，因此您得到“syntaxError: expected an indented block ”。

此外，在 Python 中，行不以分号结尾，这不是 C#。

我建议阅读基本Python 指南和阅读Python 教程
