python - 如何修复 numpy python 文件加载/写入中的逻辑错误

Question

我最近开始创建一款基于控制台的角色扮演游戏。

我编写了这段代码:

# MAIN GAME LOOP
  while True:
    if MMS == 'A': # already definied
      print('Loading Story mode...')
      print('[LOADING] Importing numpy')
      try:
        import numpy as np
      except ImportError:
        print('Error 01 // Cilent side')
        print('ImportError')
        while True:
          A = 1
      print('[LOADING] Trying load save...')
      try:
        SAVE = np.loadtxt('Savedata.dat')
        MAXLIFE = SAVE[:, 0]  # all of thesse already definied
        LIFE = SAVE[:, 1]
        MAXEN = SAVE[:, 2]
        EN = SAVE[:, 3]
        MAXOX = SAVE[:, 4]
        OX = SAVE[:, 5]
        OPOS = SAVE[:, 6]
        POS = SAVE[:, 7]
        CHAPTER = SAVE[:, 8]
        SAVE.close()
      except:
        sleep(4)
        print('[LOADING] No save file found or incorrect save.')
        print('[LOADING] Creating a new save.')
        MAXLIFE = 150
        LIFE = 110
        MAXEN = 150 
        EN = 150
        MAXOX = 150 
        OX = 85
        OPOS = 10
        POS = 10
        CHAPTER = 1
        np.savetxt('Savedata.dat', [MAXLIFE, LIFE, MAXEN, EN, MAXOX, OX, OPOS, POS, CHAPTER])

除了如果没有保存，它会创建一个具有默认值的新保存。如果有保存，游戏就会加载它。但是，它产生了无限的输出:

[LOADING] No save file found or incorrect save.
[LOADING] Creating a new save.
Loading Story mode...
[LOADING] Importing numpy
[LOADING] Trying load save...
[LOADING] No save file found or incorrect save.
[LOADING] Creating a new save.
Loading Story mode...
...

无限循环没问题，但它没有检测到之前的保存。

位于 Savedata.dat 中

1.000000000000000000e+00
1.000000000000000000e+00
1.000000000000000000e+00
1.000000000000000000e+00
1.000000000000000000e+00
1.000000000000000000e+00
1.000000000000000000e+00
1.000000000000000000e+00
1.000000000000000000e+00

我做错了什么？谢谢!

正如 hpaulj 所说，不要使用裸露的 except。我将其重写为:

except Exception as e:
    print(e)

(我知道，仅捕获异常也很糟糕)它会打印出以下内容:

Traceback (most recent call last):
  File "wakagame.py", line 21, in <module>
    MAXLIFE = SAVE[:, 0]  # all of thesse already definied
IndexError: too many indices for array

问题是您正在尝试选择列:

MAXLIFE = 保存[:, 0]

不是来自矩阵，而是来自平均一维数组:

np.savetxt('Savedata.dat', [MAXLIFE, LIFE, MAXEN, EN, MAXOX, OX, OPOS, POS, CHAPTER])

您应该将所有这些行替换为如下行:

MAXLIFE = 保存[0]

(另请注意，SAVE 是一个 numpy 数组，而不是文件，因此 SAVE.close() 将返回错误。您应该删除此行)
