用python的open()函数打开文件时，
1、文件写绝对路径报IOError: [Errno 2] No such file or directory。文件改为相对路径（只写文件名）解决该问题
2、文件是docx类型，如下代码执行时报TypeError: file() takes at most 3 arguments (4 given)path = r'file2.docx#ignore 忽略错误
f = open(path, 'r',encoding = 'utf-8',errors = 'ignore'
f = io.open(path, 'r',encoding = 'utf-8',errors = 'ignore')
