Question

我正在制作一个基本的骰子游戏，并创建了一个过程，玩家可以在其中确认或重命名。而且我用来存储玩家名称的p1变量仅在该函数内起作用，但我想在整个程序中使用它

我已经尝试过在函数之前定义变量，但该变量不起作用，并尝试在函数中先写入Global，但提示“语法无效”

#Functions
p1 = ""

def P1Start(): 
   print("Player 1 type your name")
   p1 =  str(input())
   print("Are you sure this is your name", p1)
   time.sleep(timesleep)
   print("Type YES to confirm")
   time.sleep(timesleep)
   print("Type NO to decline")

def P1Creation():
   P1confirmation = str(input()) 
   if P1confirmation =="yes":
        print("carry on")
        #elif P1confirmation == "NO" or "no":
        #P1Start()
        print(p1)
   else:
        print("Restarting the Player 1 Name Collection")
        time.sleep(1)
        P1Start()
#End of Functions

print("Welcome to the Dice game")
time.sleep(timesleep)
P1Start()
time.sleep(timesleep)
P1Creation()

print(p1)

或

#Functions
p1 = ""

def P1Start(): 
   print("Player 1 type your name")
   global p1 =  str(input())
   print("Are you sure this is your name", p1)
   time.sleep(timesleep)
   print("Type YES to confirm")
   time.sleep(timesleep)
   print("Type NO to decline")

def P1Creation():
   P1confirmation = str(input()) 
   if P1confirmation =="yes":
        print("carry on")
        #elif P1confirmation == "NO" or "no":
        #P1Start()
        print(p1)
   else:
        print("Restarting the Player 1 Name Collection")
        time.sleep(1)
        P1Start()
#End of Functions

print("Welcome to the Dice game")
time.sleep(timesleep)
P1Start()
time.sleep(timesleep)
P1Creation()

print(p1)

将Global放在前面只会显示“无效语法” 我应该怎么做才能使这项工作？

Answer 1

您不能一次完成global和一项作业。代替这个：

global p1 =  str(input())

执行以下操作：

global p1
p1 =  str(input())

Answer 2

您可以在函数本身中将其定义为全局。只是一个例子：

package.json

如何在python 3.7中使输入变量成为全局变量？
