how to fix error in python code (elif statement )

This is my code below, it is saying that there is an error but i cannot understand the error (the '^' is pointing at the ':' of the elif statement):
File "", line 47
elif:
^
SyntaxError: invalid syntax
'' print ("there are 27 sticks")
sticks = 27
player1 = True
Ai = False
print ("there are 27 sticks, pick the last one !")
print("1")
print("2")
print("3")
while player1 == True:
inp = int(input("Enter the number of sticks you want to take: "))
if inp == 1:
inp = "1: 1 stick taken"
sticks = sticks -1
print (sticks)
player1 = False
Ai = True
elif inp == 2:
inp = "2 sticks taken"
sticks = sticks - 2
print (sticks)
player1 = False
Ai = True
elif inp == 3:
inp = "3 sticks taken"
sticks = sticks - 3
print (sticks)
player1 = False
Ai = True
else:
print("Invalid input!")
while Ai == True:
if sticks == 7:
InpAi = 3
sticks = sticks - InpAi
print (sticks)
player1 = True
Ai = False
elif:
print ("")
else:
''

Your if tree in the second while loop has the structure if... elif... else but the elif doesn't have a condtion. It's throwing an error because there is no condtion.

You've declared an elif without a variable to check against, you need to put something like
elif something == 'something else':
do this

while Ai == True:
if sticks == 7:
InpAi = 3
sticks = sticks - InpAi
print (sticks)
player1 = True
Ai = False
elif: # <= add condition here if any otherwise remove that line :)
print ("")
else:
''

Simple coinflip terminal game won't update variable

I am trying to code a simple coinflip game with a gambling function. My issue is, whenever it runs, it doesn't update the balance variable. Any suggestions?
import random
balance = 10
win = "Congrats! You have won "
lose = "That's too bad, you lost this time! You now have "
start_game = False
while True:
choice = input("Please use one of these commands 'flip', 'balance', or 'end game'. ")
if choice == "flip":
start_game = True
break
elif choice == "balance":
print(balance)
elif choice == "end game":
break
else:
print("Please use one of the listed commands!")
if start_game == True:
while True:
result = random.randint(1,2)
if result == 1:
result = True
elif result == 2:
result = False
gamble_amount = input("How much would you like to flip? You have " + str(balance) + " coins. ")
if str(gamble_amount) == "balance":
print(balance)
elif int(gamble_amount) <= int(balance) and result == True:
int(gamble_amount) * 2
int(balance) + int(gamble_amount)
print(win + str(gamble_amount) + "!" + " You now have " + str(balance) + "!")
elif int(gamble_amount) <= int(balance) and result == False:
int(balance) - int(gamble_amount)
print(lose + str(balance) + " coins!")

Not recognizing tie in Tic Tac Toe AI

I am building a Tic Tac Toe AI. Here are the rules for the AI:
If there is a winning move, play it.
If the opponent has a winning move, block it.
Otherwise, play randomly.
Here's the code:
# main.py
# Prorities:
# - If there is a winning move, play it
# - If the opponent has a winning move, block it.
# - If nothing to block, make a random move.

The problem occurs when there is a tie. Either the function checkTie(), or the if statement isn't working. You might see a couple print('Check #') every once in a while. When you run the code and it's a tie, it shows all the checks going by. Which means it is passing through the check. When there is a tie, it just keeps doing the loop and repeating its turn but not making a move.
What is the mistake and how can I do this correctly?

I think your function should be
def checkTie(boxes):
for row in boxes:
for box in row:
if box != "X" and box != "O":
return False
return True
You mistyped ( I think) boxes for row in the second for statement.

def checkTie(boxes):
if any(" " in box for box in boxes):
return False
return True
Change your checkTie function to this
The rest is all good.

Making Mastermind in Python

I am simply wondering how I can make my game of Mastermind work, more specifically how I would go about making "finish" global, how I would call these functions so that the program works correctly, and overall tips that would help enhance my code. I would also like to know how to make it so the program doesn't 'reroll' the computer-generated number every single loop. This was just a difficult problem for me and I can't seem to understand how to close it out with the correct function calls and niche aspects such as that. Thank you.

Questions about a tic-tac-toe program I am writing
