# glob 模块：文件模式匹配
|
||
|
||
In [1]:
|
||
|
||
```py
|
||
import glob
|
||
|
||
```
|
||
|
||
`glob` 模块提供了方便的文件模式匹配方法。
|
||
|
||
例如，找到所有以 `.ipynb` 结尾的文件名：
|
||
|
||
In [2]:
|
||
|
||
```py
|
||
glob.glob("*.ipynb")
|
||
|
||
```
|
||
|
||
Out[2]:
|
||
|
||
```py
|
||
['11.03 json.ipynb',
|
||
'11.01 pprint.ipynb',
|
||
'11.02 pickle and cpickle.ipynb',
|
||
'11.04 glob.ipynb']
|
||
```
|
||
|
||
`glob` 函数支持三种格式的语法：
|
||
|
||
* `*` 匹配单个或多个字符
|
||
* `?` 匹配任意单个字符
|
||
* `[]` 匹配指定范围内的字符，如：[0-9]匹配数字。
|
||
|
||
假设我们要匹配第 09 节所有的 `.ipynb` 文件：
|
||
|
||
In [3]:
|
||
|
||
```py
|
||
glob.glob("../09*/*.ipynb")
|
||
|
||
```
|
||
|
||
Out[3]:
|
||
|
||
```py
|
||
['../09\. theano/09.05 configuration settings and compiling modes.ipynb',
|
||
'../09\. theano/09.03 gpu on windows.ipynb',
|
||
'../09\. theano/09.07 loop with scan.ipynb',
|
||
'../09\. theano/09.13 modern net on mnist.ipynb',
|
||
'../09\. theano/09.11 net on mnist.ipynb',
|
||
'../09\. theano/09.09 logistic regression .ipynb',
|
||
'../09\. theano/09.10 softmax on mnist.ipynb',
|
||
'../09\. theano/09.01 introduction and installation.ipynb',
|
||
'../09\. theano/09.02 theano basics.ipynb',
|
||
'../09\. theano/09.12 random streams.ipynb',
|
||
'../09\. theano/09.04 graph structures.ipynb',
|
||
'../09\. theano/09.14 convolutional net on mnist.ipynb',
|
||
'../09\. theano/09.08 linear regression.ipynb',
|
||
'../09\. theano/09.15 tensor module.ipynb',
|
||
'../09\. theano/09.06 conditions in theano.ipynb']
|
||
```
|
||
|
||
匹配数字开头的文件夹名：
|
||
|
||
In [4]:
|
||
|
||
```py
|
||
glob.glob("../[0-9]*")
|
||
|
||
```
|
||
|
||
Out[4]:
|
||
|
||
```py
|
||
['../04\. scipy',
|
||
'../02\. python essentials',
|
||
'../07\. interfacing with other languages',
|
||
'../11\. useful tools',
|
||
'../05\. advanced python',
|
||
'../10\. something interesting',
|
||
'../03\. numpy',
|
||
'../06\. matplotlib',
|
||
'../08\. object-oriented programming',
|
||
'../01\. python tools',
|
||
'../09\. theano']
|
||
``` |
