How to stop a program from closing when a file doesn't exist/cannot run

I'm trying to create a MP3 player in Python and I let the user run MP3s by inputting the name of the file. The only problem is, if the user inputs an incorrect name or a name that doesn't exist... the script closes. I was wondering if there would be a way to say:

if filedoesnotexist:

skip this line of code

Here's the actual code I'm using in the script:

class player():
    def player_name():
        Minput= input("Insert name of mp3: ")
        os.startfile("MP3_folder\\" +Minput + ".mp3")
        input("Input a key to end playback: ")
        os.system("TASKKILL /F /IM wmplayer.exe")

If you want to simply "skip this line of code" if a user enters an incorrect file name, you could use a try/except block, like so:

class player():
    def player_name():
        Minput= input("Insert name of mp3: ")
        try:
            os.startfile("MP3_folder\\" +Minput + ".mp3")
        except OSError:
            pass
        input("Input a key to end playback: ")
        os.system("TASKKILL /F /IM wmplayer.exe")

If you wanted it to return back to the beginning of the loop when/if an incorrect value is entered, you could try and use a While True loop; something like is discussed here.
