I need help with my game, help please?

[basicpythoncoderkid]

Ok, so I needed help with my game.
Here is the info. I'm running windows 8.1 pro and my python version is 3.7.5. I also use an IDE, I'm using Pycharm. Here is the code:

#start point
name = input("hello, welcome to a game. what is your name")
print ("ok, " + name + "lets go!")
ophp = 20
uhp = 50
#the main game code
while ophp or uhp > 0:
    thechoice = input("You meet ummmmm, a skeleton? 1 for Sword of Light, 2 for Empty Gun (from undertale), 3 The Really Good Steak")
    if thechoice: 1
    ophp = -5
    uhp = -2
    print("you caused " + ophp + "damage and you took " + uhp + "damage.")
    print("\a")
    elif thechoice: 2
    ophp = -10
    uhp = -2
    print("you caused " + ophp + "damage and you took " + uhp + "damage.")
    elif thechoice 3:
    print("\a")
    uhp = +5
    print("you restored 5 hp!")
else:
 print ("what?")
if uhp >1:
    print("\a")
    print("you lost.")
    input("/n/nPress the enter key to exit, and well you got the bad ending, so yeah.")
else:
    print("\a")
    print("You win!")
    input("/n/nPress the enter key to exit.")

and here's the error.

Error:

    elif thechoice: 2
       ^

Do you have any idea to fix this error? And also fix any other bugs? Please no bullying or trolling! I just needed help!
