hint can be specified to control the number of lines read: no more lines will be read if the total size (in bytes/characters) of all lines so far exceeds hint. 翻译:hint参数可以指定提示来控制读取的行数:如果到目前为止所有行的总大小(以字节/字符为单位)超过提示,则不会再读取任何行。
content = f1.read() print(content) 1.open()内置函数,open底层调用的是操作系统的接口。 2.f1变量,又叫文件句柄,通常文件句柄命名有f1,fh,file_handler,f_h,对文件进行的任何操作,都得通过文件句柄.方法的形式。 3.encoding:可以不写。不写参数,默认的编码本是操作系统默认的编码本。windows默认gbk,linux...

有了这些可用的属性,我们将调用我们的read_dollar_i()函数,并向其提供第三个元组,文件对象句柄。如果这是一个有效的$I文件,该方法将从原始文件中返回提取的元数据字典,否则返回None。如果文件有效,我们将继续处理它,将文件路径添加到$I文件的file_attribs字典中:...
