先介绍一下os.listdir()方法,此方法返回一个列表,其中包含有指定路径下的目录和文件的名称
- import os
- dirct = '/home/workespace/notebook/'
- for i in os.listdir(dirct):
- print(i)
- redis
- study_test.ipynb
- mnist_dataset
- .ipynb_checkpoints
- yaml-tool
- sweetwater
- makeyourownneuralnetwork
- Untitled.ipynb

- working
- cornfield
os.path.isdir()和os.path.isfile()需要传入的参数是绝对路径,但是os.listdir()返回的只是一个某个路径下的文件和列表的名称.
常见错误:直接使用os.listdir()的返回值当做os.path.isdir()和os.path.isfile()的入参
正确用法:需要先使用python路径拼接os.path.join()函数,将os.listdir()返回的名称拼接成文件或目录的绝对路径再传入os.path.isdir()和os.path.isfile().
os.path.join()用法:

- import os
- dirct = '/home/workespace/notebook/'
- for i in os.listdir(dirct):
- fulldirct = os.path.join(dirct,i)
- print(fulldirct)
