Tic Tac toe游戏不断获得无效的语法

Question

我试图在python中制作一个tic tac toe游戏，并且在“1”之后，first.upper()上的无效语法不断出现。我甚至移动了代码，它仍然在“1”之后。如何修复代码？

first == input("Would u like to go first? 1 is Yes  2 is No \n")
if first.upper() == "1" 
    place == input("You are X where do u want to place it? \n")

Answer 1

在python中，每当你使用＆＃34; if＆＃34;声明，你必须跟上＆＃39;：＆＃39;然后去下一行。 所以它应该是：

if first.upper() == "1":
    place == input("You are X where do u want to place it? \n")

Answer 2

first = input("Would u like to go first? 1 is Yes  2 is No \n")
if first.upper() == 1: 
    place = input("You are X where do u want to place it? \n")
