更新 python 中的导入文件

Question

I am trying to import a class which I have written in Python. Let's call it XYZ. I am trying to use this in a python script.

I import this in my script.py using:

from XYZ import XYZ
xyz = XYZ()
xyz.a()
xyz.b()

Now, If I try to update my XYZ class, its not reflected when I run script.py. Is there a way to clear cache so that it looks at the latest XYZ everytime I run script.py? I tried doing:

reload(XYZ)

But that fails with:

TypeError: reload() argument must be a module

Answer 1

The imported module is recompiled each time you run script.py and reflect your changes. reload is only required if you are running interactively. If all fails try deleting the __pycache__ directory (or *.pyc files if using python 2).
