上一次用Python的2种方法遍历文件，这次参考了一下Python Promgramming 3rd 里面的代码，用os.path.walk来遍历文件，并且搜索文件里面的内容
search_content.py
import os, syslistonly = Falseskipexts = ['.gif', '.exe', '.pyc', '.o', '.a','.dll','.lib','.pdb','.mdb'] # ignore binary files def visitfile(fname, searchKey): # for each non-dir file global fcount, vcount try: if not listonly: if os.path.splitext(fname)[1] in skipexts: pass elif open(fname).read().find(searchKey) != -1: print'%s has %s' % (fname, searchKey) fcount += 1 except: pass vcount += 1 def visitor(args, directoryName,filesInDirectory): # called for each dir for fname in filesInDirectory: fpath = os.path.join(directoryName, fname) if not os.path.isdir(fpath): visitfile(fpath,args) def searcher(startdir, searchkey): global fcount, vcount fcount = vcount = 0 os.path.walk(startdir, visitor, searchkey) if __name__ == '__main__': root=raw_input("type root directory:") key=raw_input("type key:") searcher(root,key) print 'Found in %d files, visited %d' % (fcount, vcount)windows调试通过
