In path setup, I wrongly wrote the code: os.chdir = '\some path', which turns the function os.chdir() into a string. Is there any quick way to restore the function without restarting the software? Thanks!

Kicking os out of the modules cache can make it freshly importable again:

>>> import sys, os
>>> os.chdir = "d'oh!"
>>> os.chdir()
TypeError: 'str' object is not callable
>>> del sys.modules['os']
>>> import os
>>> os.chdir
<function posix.chdir>

>>> import os

Assign to the chdir method a string value:

>>> os.chdir = '\some path'
>>> os.chdir
'\some path'

Use reload to, well, reload the module. reload will reload a previously imported module.

>>> reload(os)
>>> os.chdir
<built-in function chdir>

  • While this code snippet may solve the question, [including an explanation](http://meta.stackexchange.com/questions/114762/explaining-entirely-code-based-answers) really helps to improve the quality of your post.

  • This will work as-is in Python 2, but in Python 3 onwards, `reload` needs to be imported differently. Please see [this question](https://stackoverflow.com/a/437591/8305056) for how to import `reload` depending on your version of Python. – girlvsdata Aug 22 '18 at 00:27
