1 正则表达式[^\\/:*?"<>|\r\n]+$    ---->取文件名包括后缀
 2 e.g.  >>>D:\PyCharm 2018.2.4\pythonWork\venv\Scripts\python.txt
 3         ->python.txt
 4 
 5 正则表达式(.+?)\.txt             ---->取上次结果去掉后缀
 6 e.g.  >>>python.txt
 7         ->python

 8 部分代码应用截取>>>

10     sendfile = tk.Tk()
11     sendfile.withdraw()

13     file_path = filedialog.askopenfilename()
14     print(file_path)
15 
16     newName = re.findall(r'[^\\/:*?"<>|\r\n]+$',file_path)
17     newName =  re.findall(r'(.+?)\.txt',newName[0])
18 
19     os.system('python markup.py < %s > d:/%s.html '%(file_path,newName[0]))

 

取路径中最后一个‘/’前的所有内容包括最后一个‘/’
