I want to make a in-memory file to use in pygame mixer. I mean something like which says load() method supports file object.
import requests
from pygame import mixer
r = requests.get("")
in_memory_file = file(r.content) # something like this
mixer.music.init()
mixer.music.load(in_memory_file)
mixer.music.play()

You are probably looking for BytesIO or StringIO classes from Python io package, both available in python 2 and python 3. They provide a file-like interface you can use in your code the exact same way you interact with a real file.
StringIO is used to store textual data:
import io
f = io.StringIO("some initial text data")
BytesIO must be used for binary data:
import io
f = io.BytesIO(b"\x00\x00\x00\x00\x00\x00\x00\x00\x01\x01\x01\x01\x01\x01")
To store MP3 file data, you will probably need the BytesIO class. To initialize it from a GET request to a server, proceed like this:
import requests
from pygame import mixer
import io
r = requests.get("")
inmemoryfile = io.BytesIO(r.content)
mixer.music.init()
mixer.music.load(inmemoryfile)
mixer.music.play()
# This will free the memmory from any data
inmemoryfile.close()
Additional note: as both classes inherit from IOBase, they can be used as context manager with the with statement, so you don't need to manually call the close() method anymore:
import requests
from pygame import mixer
import io
r = requests.get("")
with io.BytesIO(r.content) as inmemoryfile:
mixer.music.init()
mixer.music.load(inmemoryfile)
mixer.music.play()
