【问题描述】：

嗯，我遇到了这个网站，我有一个问题需要回答。我有一个起始游戏代码（它是由 Python 的 Turtle 创建的）。而且我在第 21 行不断收到语法错误。如果我更改该行的代码也没关系，它会不断弹出。希望大家帮忙。

import turtle
import time

wn = turtle.Screen()
wn.bgcolor('black')
startingTurtle = turtle.Turtle()
backHigh = turtle.Turtle()

score=0
lives=3
entrance_time=5

while entrance_time == 5:
  entrance = turtle.Turtle()
  entrance.hideturtle()
  entrance.penup()
  entrance.speed(0)
  entrance.color('#F54747')
  entrance.goto(-85, 100)
  entrance.write("Alien Shooter", font=(None, 25, "bold")
  entrance.time.sleep(0.5)
  entrance.color('#46F2AB')
  entrance.write("Alien Shooter", font=(None, 25, "bold")
  entrance.time.sleep(0.5)
  entrance.color('#F2E446')
  entrance.write("Alien Shooter", font=(None, 25, "bold")
  entrance.time.sleep(0.5)
  entrance.color('#F2466C')
  entrance.write("Alien Shooter", font=(None, 25, "bold")
  entrance_time=entrance_time-1
  entrance.time.sleep(1)

【问题讨论】：

哦，如果可以的话。请问一下，为什么我按字母“P”时不弹出游戏菜单，但按字母“H”时弹出高分。

你能帮我们找出第 21 行吗？

请发布完整的错误回溯。查看如何发布minimal reproducible example

@Wanderer 请不要...由于很多原因，屏幕截图很糟糕。

并投票结束：印刷错误。 entry.time.sleep(0.5) 是第 21 行，问题是它之前的行缺少右括号。应该是 entry.write("Alien Shooter", font=(None, 25, "bold") )

【参考方案1】：

尝试在 entrance.write 行的末尾添加一个结束 )。他们似乎不见了。可能还有其他错误，但这应该可以解决其中的一些错误。

至于您的P 键不起作用。 P 正在调用函数 startGame。这似乎不是正确的功能。
