python 好久不用，基础重拾系列（1，List转str；2，快速在字符串中查找到特定小字符串）

1 def List2Str(list):
2     value=[str(i) for i in list]
3     Value_str=''.join(value)
4     return Value_str

1 import re  
2 text = "/User/lijian/Desktop/workspace/project/V501/name/" 
3 searchContext = "/" 
4 numList = [m.start() for m in re.finditer(searchContext, text)]
5 print numList
