isFile = os.path.isfile(fpath) isDirectory = os.path.isdir(fpath)两个方法都将返回一个布尔值,指示出该文件路径是否是一个文件,或者是否是一个目录。5.1. 检查指定路径是否是一个文件接下来我们先执行上面写入代码将 sample.txt 创建好,然后判断其是否文件。#...

read(size),每次读取size个字节的内容,适合于未知文件大小的读取; readline( ),每次读取一行内容; readlines( ),一次性读取所有内容,并按行返回list,适用于配置文件的读取。 file-like Object:像open()函数返回的这种有个read()方法的对象,在Python中统称为file-like Object。除了file外,还可以是内存的字节流,网...
