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:
glob.glob("*.ipynb")
['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:
glob.glob("../09*/*.ipynb")
['../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:
glob.glob("../[0-9]*")
['../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']
