在Python 3中,reload函数的变化及其使用方法如下: Python 3中reload函数的变化: 在Python 2中,reload是一个内置函数,可以直接使用来重新加载一个模块。但在Python 3中,reload函数被移除出了内置函数,并被移到了importlib模块中。这意味着在Python 3中,你不能直接使用reload函数,除非你首先从importlib模块中导入它。
首先:cmd后,输入pip list 查看我已经安装了的程序,发现报错:Error in sitecustomize; set PYTHONVERBOSE for traceback: NameError: name 'reload' is not defined 百度发现了解决办法:将路径D:\python3\Lib\site-packages下文件sitecustomize.py改成sitecustomize_back.py 按照这个步骤,完美解决了问题。 绕后我用pi...

4、笔者又不厌其烦的跑去百度,各种度,国内外的,最后发现了预料中的一件事,在Python 3.x中不好使了提示name reload’ is not defined,在3.x中已经被毙掉了被替换为 import importlib importlib.reload(sys) 并且,Python 3默认是utf8编码格式,我了各种去,心里一万只草泥马,同样是python,python2和python3咋就...

I was overjoyed when I discovered this, since addSlashIfNecessary() is one of the stupid little functions I always need to write when building up my toolbox in a new language. Do not write this stupid little function in Python; smart people have already taken care of it for you. os...
