下面是@RichieHindle的精彩答案的一个变体，它实现了一个可以选择性地应用于所需函数的装饰器。适用于Python 2.7.14和3.6.4。

from __future__ import print_function
import functools
import traceback
import sys

INDENT = 4*' '

def stacktrace(func):
    @functools.wraps(func)
    def wrapped(*args, **kwds):
        # Get all but last line returned by traceback.format_stack()
        # which is the line below.
        callstack = '\n'.join([INDENT+line.strip() for line in traceback.format_stack()][:-1])
        print('{}() called:'.format(func.__name__))
        print(callstack)
        return func(*args, **kwds)

    return wrapped

@stacktrace
def test_func():
    return 42

print(test_func())

样本输出:

test_func() called:
    File "stacktrace_decorator.py", line 28, in <module>
    print(test_func())
42

import traceback
traceback.print_stack()

下面是一个通过traceback模块获取堆栈并打印的例子:

import traceback

def f():
    g()

def g():
    for line in traceback.format_stack():
        print(line.strip())

f()

# Prints:
# File "so-stack.py", line 10, in <module>
#     f()
# File "so-stack.py", line 4, in f
#     g()
# File "so-stack.py", line 7, in g
#     for line in traceback.format_stack():

如果你真的只想打印堆栈到stderr，你可以使用:

traceback.print_stack()

或者打印到stdout(如果想保持重定向输出在一起很有用)，使用:

traceback.print_stack(file=sys.stdout)

但是通过traceback.format_stack()获取它可以让你对它做任何你喜欢的事情。

对于那些在使用pdb时需要打印调用堆栈的人，就这样做吧

(Pdb) where

Inspect.stack()返回当前堆栈，而不是异常回溯:

import inspect
print inspect.stack()
