# Below is an example of a tool that does nothing. Amaze us with your creativity !
# I made a weather tool based on a location city using the requests import to get the weather at a given city
# It works but for some reason if you ask it to do 2 things 
# (eg. "Can you tell me the Time in America/Chicago and the weather in Houston?") 
# It will successfully return the time but fail to return the weather and I do not know why

# edit, if you ask for the weather before asking for the time, I'm not sure if this is an LLM issue or a code issue
