Help me with this connect issue, please.

I just ran your code and got no error. Try uninstalling and reinstalling nats:

pip install nats-py

The solution is to rename your file to anything else.

When you type import nats python recursively tries to find a file or folder named nats. In this case the first file if will find is nats.py.

You never define a function named connect in your nats.py so that fails. You want to instead let the recursive import continue upto site_packages where the actual nats folder is that contains the connect function.

For example, if you name this file hello.py:

import hello

print(hello.hello)
print(hello)
print(hello.hello.hello)

You will see that all 3 print statements print the same thing, since hello will be the file itself.

Simply renaming your file anything else will prevent python from finding the module too soon and will keep searching till it find the correct module.
