glob

sys.path[0] 获得当前目录
当前目录为：F:/PycharmProjects/NIP-keyword extraction 子目录如下：
在这里插入图片描述

NlP-keyword子目录为：

glob支持 * ? [] 这三种通配符

*代表0个或多个字符
?代表一个字符
匹配指定范围内的字符，如[0-9]匹配数字

glob.iglob

iglob与glob类似，只是这里返回值为迭代器，对于大量文件时更为省内存

import sys
from glob import glob,iglob
x = iglob(sys.path[0]+'/*/*.py')
print(x)

结果：

<generator object _iglob at 0x00000205A493C410>

##############################################################################################

import sys
from glob import glob,iglob
for x in iglob(sys.path[0]+'/*/*.py'):
    print(x)

结果

F:\PycharmProjects\NIP-keyword extraction\NIP-keyword\crfsuite_model.py
F:\PycharmProjects\NIP-keyword extraction\NIP-keyword\evaluate.py
F:\PycharmProjects\NIP-keyword extraction\NIP-keyword\preprocessing.py
F:\PycharmProjects\NIP-keyword extraction\NIP-keyword\submit.py

glob.glob

得到的是一个list

import sys
from glob import glob,iglob
x = glob(sys.path[0]+'/*/*.py')
print(x)
print(type(x))

结果：

['F:\\PycharmProjects\\NIP-keyword extraction\\NIP-keyword\\crfsuite_model.py', 'F:\\PycharmProjects\\NIP-keyword extraction\\NIP-keyword\\evaluate.py', 'F:\\PycharmProjects\\NIP-keyword extraction\\NIP-keyword\\preprocessing.py', 'F:\\PycharmProjects\\NIP-keyword extraction\\NIP-keyword\\submit.py']
<class 'list'>

遍历指定文件夹下所有文件或文件夹（不能遍历文件夹中的文件）

import sys
from glob import glob
for x in glob(sys.path[0]+'/*'):
    print(x)

结果：

F:\PycharmProjects\NIP-keyword extraction\1.py
F:\PycharmProjects\NIP-keyword extraction\NIP-keyword
F:\PycharmProjects\NIP-keyword extraction\tta_test.ipynb

遍历指定文件夹下的所有文件夹里的所有文件，//可以根据文件夹层数自主设定

import sys
from glob import glob
for x in glob(sys.path[0]+'/*/*'):
    print(x)

结果：
