file.read([size]):size 未指定则返回整个文件,如果文件大小 >2 倍内存则有问题,f.read()读到文件尾时返回""(空字串)。 file.readline():返回一行。 file.readlines([size]) :返回包含size行的列表, size 未指定则返回全部行。 for line in f: print line :通过迭代器访问。也可以是for i in file....

1.with open() as file Python内置了读写文件的函数,用法和C是兼容的。在磁盘上读写文件的功能都是由操作系统提供的,现代操作系统不允许普通的程序直接操作磁盘,所以,读写文件就是请求操作系统打开一个文件对象(通常称为文件描述符),然后,通过操作系统提供的接口从这个文件对象中读取数据(读文件),或者把数据写入...

with open() as file: 是Python 中用于打开文件的语法结构。 with 和as 是Python 的关键字,用于创建一个上下文环境,确保在离开该环境时资源能够被正确关闭或释放。 open() 是一个内置函数,用于打开文件并返回一个文件对象。 open(file, mode='r', buffering=-1, encoding=None, errors=None, newline=None,...
