im creating a rock paper scissors game and for some reason my elifs are not working. keep in mind that im not great at python and i just need an explanation and an example as to how i need to fix it so i can fix it if i run into the same problem at a later date. thanks!

import random
yw="you win"
yl="you lose"
yt="you tie"

uw=0
pw=0

ps=random.randint(1,3)

print("btw computer choices are displayed as 1,2,3. 1=rock, 2=scissors, 3=paper")

while (uw<3) or (pw<3):
  if uw==3:
    print("you win *overall*")
    break
  if pw==3:
    print("you lose *overall*")
    break
  us=input("choose a move rock paper or scissors!")
  ps=random.randint(1,3)
  if us=="rock":
    print("you chose {}".format(us))
  elif us=="paper":
    print("you chose {}".format(us))
  elif us=="scissors":
    print("you chose {}".format(us))
  else:
    print("you lose")
    pw+=1  
  elif us=="rock":
    if ps==2:
      print(ps)
      print(yw)
     uw+=1
    elif:
      print(ps)
      print(yl)
      pw+=1
    else:
      print(ps)
      print(yt)      
  elif us=="scissors":
    if ps==3:
      print(ps)
      print(yw)
      uw+=1
    elif:
      print(ps)
      print(yl)
      pw+=1
    else:
      print(ps)
      print(yt)
  elif us=="paper":
    if ps==1:
      print(ps)
      print(yw)
      uw+=1
    elif:
      print(ps)
      print(yl)
      pw+=1
    else:
      print(ps)
      print(yt)

i was expecting to be able to run my code but instead it gives me a syntax error. there isnt a missing if before it and i really dont know whats wrong. thanks!your text
