# ### Define Functions
# 
# As demonstrated in the OpenAI documentation, here is a simple example of how to define the functions that are going to be part of the request. 
# 
# The descriptions are important because these are passed directly to the LLM and the LLM will use the description to determine whether to use the functions or how to use/call.



# # define a function as tools
# tools = [
#     {
#         "type": "function",
#         "function": {
#             "name": "get_current_weather",
