• sort by ext

 

I would like to give some feedback about ... i don't know how to do with ".bat" or '.aa.doc'

    def sort_by_ext(files: List[str]) -> List[str]:

files=sorted(files)
files=sorted(files, key=lambda x: x[2:len(x)])
return files

sortbyext(['1.cad', '1.bat', '.aa', '.bat']) == ['.aa', '.bat', '1.bat', '1.cad'] sortbyext(['1.cad', '1.bat', '1.aa', '1.aa.doc']) == ['1.aa', '1.bat', '1.cad', '1.aa.doc']

Your result:["1.aa",".bat","1.bat","1.cad"] Right result:[".bat","1.aa","1.bat","1.cad"]
