python包：glob用法

python的glob包用法：
该包包含两个主要的函数glob和iglob，输入参数均是文件路径，返回值glob为文件列表（无序），iglob为迭代器：

glob.glob(pathname)¶Return a possibly-empty list of path names that match pathname, which must be a string containing a path specification. pathname can be either absolute (like /usr/src/Python-1.5/Makefile) or relative (like ../../Tools/*/*.gif), and can contain shell-style wildcards. Broken symlinks are included in the results (as in the shell).glob.iglob(pathname)Return an iterator which yields the same values as glob() without actually storing them all simultaneously.

例如：

import globa=glob.iglob(r'F:\my\*.pdf')for i in a:    print(i)

输出：

F:\my\HMEC_100kb_MAPGE30.pdfF:\my\HMEC_100k_MAPG0.pdfF:\my\HMEC_100k_MAPGE30.pdfF:\my\HMEC_5k_MAPG0.pdfF:\my\IMR90_100kb_MAPG0.pdfF:\my\IMR90_100k_MAPG0.pdf
