Replit DB没有将数据加载到变量中。

Question

我使用的是复制数据库，但是当我试图加载它时，会返回一个错误

有什么想法吗？

cookie = db[name]
cookiepc = db[name + "cookiepc"]
increase = db[name + "increase"]

错误是

Traceback (most recent call last):
  File "main.py", line 25, in <module>
    cookiepc = db[name + "cookiepc"]
  File "/home/runner/Cookie-clicker/venv/lib/python3.8/site-packages/replit/database/database.py", line 439, in __getitem__
    raw_val = self.get_raw(key)
  File "/home/runner/Cookie-clicker/venv/lib/python3.8/site-packages/replit/database/database.py", line 479, in get_raw
    raise KeyError(key)
KeyError: 'shdfgwbdhfbadwcookiepc'

根据the documentation for replit-py，当尝试从数据库中不存在的键读取时会引发KeyError。

如果键不存在，可以使用db.get指定默认值：

print(db.get("b", "default")) # default
db["b"] = "pie"
print(db.get("b", "default")) # pie
