How to import module in Thonny?

Hi
Lets say I have a python script and it has a line such as “import wificonfig”.
When I run the script in Thonny it gives me an error such as " ImportError: no module named ‘wificonfig’".
So I go to github and find this module called “wificonfig.py”.
The question is how do I import this into Thonny so I dont get the error message when I run the python script.?

Since I’m not 100% sure?
Pi or Pico?
Python or Micro Python?

I,m using the interstate 75w that has a pico w with micro python.

You do a file save as. and save to the pico. That file needs to be edited for wifi setup.

So basically I simply save the module to the same directory as my main script, correct?

Yes, sorry for the short low on details answer.
pimoroni-pico/micropython/examples/galactic_unicorn at main · pimoroni/pimoroni-pico (github.com)

Wireless Examples

These examples require WIFI_CONFIG.py and network_manager.py (from the common directory) to be saved to your Pico W. Open up WIFI_CONFIG.py in Thonny to add your wifi details (and save it when you’re done).

Thanks for talking the time to reply.
