Question

我正在尝试解析一列用分号分隔的单元格。该列如下所示：

@bot.command()
async def repeat(times: int, *,content="Repeating..."):
  for i in range(times):
    if times > 10:
      await bot.say("Cannot spam more than 10 messages at a time.")
      return
    else:
      await bot.say(content)

现在，我正在编写一个简单的循环，以将该列解析为唯一列表：

Operations
ANALYSIS; LABEL; MANUFACTURE; PACK; STERILIZE
ANALYSIS; LABEL; PACK; STERILIZE
API MANUFACTURE

熊猫吐出如下错误：

a=list()
for i in range(9552):
    a+=ops_list[i].split(";")

但是，如果我只是在每个循环中进行如下打印：

    ---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)

      2 for i in range(9552):

KeyError: 8167

有效。

Answer 1

您应使用EmployeeID LastName ReportsTo level ----------- -------------------- ----------- ----------- 2 Fuller NULL 0 --anchor call --now 'Managers' CTE is the anchor (level 0) 1 Davolio 2 1 3 Leverling 2 1 4 Peacock 2 1 5 Buchanan 2 1 8 Callahan 2 1 --now 'Managers' CTE is resultset level 1 6 Suyama 5 2 7 King 5 2 9 Dodsworth 5 2：

tolist

Answer 2

结果是需要重新索引输入数据帧。我刚刚更改了索引号，现在它可以工作了.....

带有KeyError的熊猫简单循环：8167
