Question

我已经看过其他关于此的帖子，但我是初学者，并且不了解我见过的其他大部分内容。如果有人可以解释做什么以及如何工作，将不胜感激！这是代码。

import time
import sys 
import random
done = False
day = 1
v = 2
v2 = 2
gas = 2
gas2 = 2
# thrist
dt = 0
dt2 = 0
# hunger
dh = 0
dh2 = 0
#sanity
ds = 100
ds2 = 100
#water
water = 5
water2 = 5
#food
food = 5
food2 = 5
def cls():
  for i in range(10):
    print('\n' * 100)
title = input('Press ENTER to start.')
cls()
playercount = input('How many players are playing?')
def player1():
  start = input('''
  Objective: Survive the nuke drop for 30 days.
  Items: 
    - Food
      + 5
    - Water
      + 5
    - Gas Mask
    - Medkit
    - Gun
      + 1 ammo
    - Axe
    - Board Games
  Survivors:
    - You
  ''')
  cls()
  time.sleep(2)
  while not done:
    if dt > 5 and dt < 10:
      input('You are getting thirsty.')
    if dh > 5 and dh < 10:
      input('You are getting hungry.')
    if ds > 50 and ds < 70:
      input('You are starting to go insane!')
    if dt > 15:
      input('You died of thirst')
      sys.exit()
    if dh > 15:
      input('You died of hunger!')
      sys.exit()
    if ds < 50:
      input('You became insane!')
      sys.exit()

这是错误

Traceback (most recent call last):
  File "main.py", line 892, in <module>
    player1()
  File "main.py", line 261, in player1
    if dt > 5 and dt < 10:
UnboundLocalError: local variable 'dt' referenced before assignment

在我的代码中，这会发生多次提示帮助！

Answer 1

调用函数时，如果该函数有一个未通过参数导入或未在其中声明的变量;然后发生这样的错误。

当您调用函数player1()时，python无法找到变量dt，因为您已将其声明在您尝试使用它的范围之外。使用参数在函数内部dt或在player1()函数内声明它。

对ds和dh变量也一样。
