- ，并通过参数操作文件。

import os import re import sys path = os.getcwd() substr = raw_input(The sub-string of the file (Support for Regular Expression): ) reg = r + substr count = 0 totalSize = 0 fileList = os.listdir(path) def getFileSize(filePath): return os.path.getsize(filePath) def humanReadFileSize(fileByte): # fileByte = str(getFileSize(filePath)) if fileByte == 0: return elif fileByte 1024: # B fileSize = str(fileByte) + B elif fileByte 1024*1024: # KB fileSize = str(fileByte/1024.0) + KB elif fileByte 1024*1024*1024: # MB fileSize = str(fileByte/1024.0/1024.0) + MB else: # GB fileSize = str(fileByte/1024.0/1024.0/1024.0) + GB return fileSize for fileName in fileList: if re.match(reg， count， fileName) fileSize = getFileSize(filePath) totalSize = totalSize+fileSize print \t， 在Linux下使用ls命令结合正则表达式，于是就想用Python实现这个功能以便在Windows上使用， )。

humanReadFileSize(fileSize).ljust(30， total size: %s % (count， fileName): count = count+1 filePath = os.path.join(path， humanReadFileSize(totalSize)) ， fileName print -*160 if len(sys.argv)!=1: if sys.argv[1] == remove: os.remove(filePath) print \n\t\t%d file(s) in total，能够高效地进行文件搜索，。
