您可以记录堆栈跟踪而不出现异常。

https://docs.python.org/3/library/logging.html#logging.Logger.debug

The second optional keyword argument is stack_info, which defaults to False. If true, stack information is added to the logging message, including the actual logging call. Note that this is not the same stack information as that displayed through specifying exc_info: The former is stack frames from the bottom of the stack up to the logging call in the current thread, whereas the latter is information about stack frames which have been unwound, following an exception, while searching for exception handlers.

例子:

>>> import logging
>>> logging.basicConfig(level=logging.DEBUG)
>>> logging.getLogger().info('This prints the stack', stack_info=True)
INFO:root:This prints the stack
Stack (most recent call last):
  File "<stdin>", line 1, in <module>
>>>

如果你可以处理额外的依赖，那么使用twisted.log，你不必显式地记录错误，而且它还会返回整个回溯和时间到文件或流。

使用exc_info选项可能更好，允许你选择错误级别(如果你使用exception，它将总是在错误级别):

try:
    # do something here
except Exception as e:
    logging.critical(e, exc_info=True)  # log exception info at CRITICAL log level

在日志模块(如果是自定义模块)中启用stack_info。

api_logger.exceptionLog("*Input your Custom error message*",stack_info=True)

这个答案是建立在上述优秀答案之上的。

在大多数应用程序中，您不会直接调用logging.exception(e)。很可能你已经为你的应用程序或模块定义了一个自定义记录器，如下所示:

# Set the name of the app or module
my_logger = logging.getLogger('NEM Sequencer')
# Set the log level
my_logger.setLevel(logging.INFO)

# Let's say we want to be fancy and log to a graylog2 log server
graylog_handler = graypy.GELFHandler('some_server_ip', 12201)
graylog_handler.setLevel(logging.INFO)
my_logger.addHandler(graylog_handler)

在这种情况下，只需使用记录器调用异常(e)，如下所示:

try:
    1/0
except ZeroDivisionError, e:
    my_logger.exception(e)

记录器。异常将在错误消息旁边输出堆栈跟踪。

例如:

import logging
try:
    1/0
except ZeroDivisionError:
    logging.exception("message")

输出:

ERROR:root:message
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ZeroDivisionError: integer division or modulo by zero

@Paulo支票笔记，“注意在python3中你必须调用日志记录。except部分中的异常方法。如果在任意位置调用此方法，可能会得到一个奇怪的异常。医生对此提出了警告。”
