我在python上做了一个“help(inspect.getouterframes)”,这就是它给了我的东西:
getouterframes(frame, **context**=1)
Get a list of records for a frame and all higher (calling) frames.
Each record contains a frame object, filename, line number, function
name, a list of lines of context, and **index within the context**.
我只是想知道......这些“背景”和“指数”是什么意思?
谢谢!

从当前行的周围代码中添加一些上下文。简单的例子:
import sys
import inspect
def f():
# prev
return sys._getframe()
# next
# prev
framelist = inspect.getouterframes(f(), 3)
# next
for frame in framelist:
print frame[3], "context:\n"
for i, line in enumerate(frame[-2]):
print line.rstrip(),
if i == frame[-1]:
print ' *** index ***'
else:
print
print
输出:
f context:
# prev
return sys._getframe() *** index ***
# next
<module> context:
# prev
framelist = inspect.getouterframes(f(), 3) *** index ***
# next
