Python notes search for files under the specified path by file name

1. Search file name beginning with the specified string (e.g. search DLL, results containing DLL a,dll ABC, etc.)

My directory has DLLs A.txt and dll.txt files

Where a folder has these two files

I want to find the four files by Python by choosing the keyword DLL.

Import OS

Result=[]
def search (path= ".", Name= ""):
    For item in Os.listdir (path):
        Item_path = Os.path.join (path, item)
        If Os.path.isdir (Item_path):
            Search (Item_path, name)
        Elif Os.path.isfile (Item_path):
            If name in item:
                Global result
                Result.append (Item_path + ";")
                Print (Item_path + ";", end= "")

Search (path=r "D:\newfile", name= "DLL")

Output Result:

2. If I only want to find out the TXT named DLL, do not DLL a.txt, that is, the keyword match above, this time instead of full match. Then we need to search for the specified file name.

As long as the code in the above

    If name in item:

Switch

     If name+ ". txt" = = Item:
