是否可以打印poloniex错误消息

Question

我尝试使用Poloniex模块将加密货币从我的Poloniex钱包提取到python中的外部钱包，该模块与以下代码配合得很好：

from poloniex import Poloniex
from poloniex import PoloniexCommandException
polo = Poloniex("my_api_key", "my_api_secret")
try: 
r = polo.withdraw(currency = "LTC", amount = "0.5", address = "MH...W5")
except PoloniexCommandException:
print("doesn't work")
else:
print("successful")
print(r["response"])

如果在提款过程中没有错误，一切都很好。如果出现错误(我没有足够的余额或地址错误(，它将按预期打印doesn't work。如果我打印r，我会得到以下错误：

Traceback (most recent call last):
File "c:UsersphilDesktopPythonpoloniextest.py", line 12, in <module>
r = polo.withdraw(currency = "LTC", amount = "0.5", address = "MH...W5")
File "C:UsersphilsAppDataLocalProgramsPythonPython39libsite-packagespoloniexpoloniex.py", line 300, in withdraw
return self._private('withdraw', currency=currency, amount=amount,
File "C:UsersphilAppDataLocalProgramsPythonPython39libsite-packagespoloniexpoloniex.py", line 50, in _fn
raise PoloniexCommandException(respdata['error'])
poloniex.exceptions.PoloniexCommandException: Not enough LTC.

现在我想从错误中打印此消息：Not enough LTC.

可以打印这封信吗？

如果将Exception保存在变量中，则可以轻松打印错误消息：

except PoloniexCommandException as e:
print(e)
