python - reload(sys)报Undefined variable: reload错误

Question

author = 'jyang'
import sys
import json
reload(sys)
sys.setdefaultencoding('utf-8')
还报Undefined variable from import: setdefaultencoding错误

Answer 1

What version of python?

Answer 2

There is a possibility that python3 has been used
reload has been placed in another location,

from imp import reload

But sys.setdefaultencoding('utf-8') is no longer meaningful,
Because python3 uses unicode, there is no need to set utf-8 anymore

Answer 3

from importlib import reload
reload(modulename)
