In this tutorial, you'll be examining a couple of methods to get a list of files and folders in a directory with Python. You'll also use both methods to recursively list directory contents. Finally, you'll examine a situation that pits one method against
my_list=["apple","banana","orange","grape"] 1. 将List数据输出到文本文件 如果我们想要将List中的数据输出到文本文件中,可以使用Python内置的open()函数和文件操作。 下面的代码示例展示了如何将List中的数据逐行写入到一个文本文件中: withopen("output.txt","w")asfile:foriteminmy_list:file.write(it...

os.walk()函数的返回值是一个生成器(generator),每次遍历的对象都是返回的是一个三元组(root,dirs,files):该元组有3个元素,这3个元素分别表示每次遍历的路径名,目录列表和文件列表。 root代表当前遍历的目录路径,string类型。 dirs代表root路径下的所有子目录名称;list类型,列表中的每个元素是string类型,代表子目录...
