[英]TypeError: tuple indices must be integers or slices, not str in command
嗨,我收到此錯誤: TypeError: tuple indices must be integers or slices, not str in command
此命令中的TypeError: tuple indices must be integers or slices, not str in command
命令,我有點不確定我在哪里出錯。 這是我正在使用的代碼:
@checks.can_embed()
@commands.command(name="botinfo")
async def botinfo(self, ctx: UKGCtx):
"""Shows advanced information about the bot."""
char_count = 0
deaths_count = 0
levels_count = 0
with closing(userDatabase.cursor()) as c:
c.execute("SELECT COUNT(*) as count FROM chars")
result = c.fetchone()
if result is not None:
char_count = result["count"]
c.execute("SELECT COUNT(*) as count FROM char_deaths")
result = c.fetchone()
if result is not None:
deaths_count = result["count"]
c.execute("SELECT COUNT(*) as count FROM char_levelups")
result = c.fetchone()
if result is not None:
levels_count = result["count"]
fetchone
返回一個序列(在這種情況下為元組)或None
,而不是字典。
如果您希望它返回字典,則可以從文檔中像以下示例一樣替換Connection.row_factory
:
import sqlite3
def dict_factory(cursor, row):
d = {}
for idx, col in enumerate(cursor.description):
d[col[0]] = row[idx]
return d
con = sqlite3.connect(":memory:")
con.row_factory = dict_factory
cur = con.cursor()
cur.execute("select 1 as a")
print(cur.fetchone()["a"])
