Why 'open' is not a function according to inspect module?

[Peng Yu]

Hi,

'open' is not a function according to inspect module. But according to
help(open), it is a function. Is there something wrong with inspect
module?

$ cat main.py
#!/usr/bin/env python

import inspect

def hello():
print "Hello World!"
return

print inspect.isfunction(str)
print inspect.isfunction(open)
print inspect.isfunction(hello)

$ ./main.py
False
False
True

Help on built-in function open in module __builtin__:

open(...)
open(name[, mode[, buffering]]) -> file object

Open a file using the file() type, returns a file object. This is the
preferred way to open a file.
