# 这次是把specialtopic下面所有的代码中删除掉cmonitor.字样
import os,re

# 获得所有的代码文件绝对路径列表

	allfiles = []
	for parent,dirnames,filenames in os.walk(path):
		for filename in filenames:
			allfiles.append(os.path.join(parent,filename))	
	return allfiles

# 替换指定文件里面的字符

	F = open(f)
	try:
		F_Text = F.read()
	finally:
		F.close()
	bak = F_Text.replace('cmonitor.','')
	open(f,'w').write(bak)
