AI Python

Notes from the course of DeepLearning.AI - AI Python for Beginners

Mostly these are examples of practical use but you can have an overview to know how you could adapt them to you context.

• Check out my page on python if you need a refresher on python here

Create an environment to use AI in Python script

Installations

If you want an all made setup, you can install Anaconda from here. In linux you just have to run bash Anaconda3-2024.10-1-Linux-x86_64.sh Once this is done you will have access to a gui to create your Jupyter notebook To launch said gui you can do as follow:

cd anaconda3
cd bin
./anaconda-navigator

You will need to create and account in anaconda cloud and login.

• If you need any help, you can find the official doc here

Setting up the API key

import os
from dotenv import load_dotenv
from openai import OpenAI

# Get the OpenAI API key from the .env file
## For security reason I recommend that you rather use a vault with password rotation if you want to deploy something more permanently
load_dotenv('.env', override=True)
openai_api_key = os.getenv('OPENAI_API_KEY')
client = OpenAI(api_key = openai_api_key)

# Method to get llm response
def get_llm_response(prompt):
    completion = client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[
            {
                "role": "system",
                "content": "You are an AI assistant.",
            },
            {"role": "user", "content": prompt},
        ],
        temperature=0.0,
    )
    response = completion.choices[0].message.content
    return response

# test our method
prompt = "What is the capital of France?"
response = get_llm_response(prompt)
print(response)

# We can modify the temperature to change the randomness of the output
def get_llm_response_new_temp(prompt):
    completion = client.chat.completions.create(
        model="gpt-4o-mini",
        messages=[
            {
                "role": "system",
                "content": "You are an AI assistant.", 
            },
            {"role": "user", "content": prompt},
        ],
        temperature=1.0, # change this to a value between 0 and 2
    )
    response = completion.choices[0].message.content
    return response

Building LLM prompts with variables

from helper_functions import print_llm_response
print_llm_response("What is the capital of France?")
# Will print "The capital of France is Paris."
number_of_lines = 8
prompt = f"generate a poem with {number_of_lines} lines"
print_llm_response(prompt)
print(prompt)
# Will print a poem with 8 lines
# Would also work this way
number_of_lines = 8
prompt = f"generate a poem with {number_of_lines} lines"
response = get_llm_response(prompt)
print(response)

Iteratively updating AI prompts using lists

from helper_functions import print_llm_response, get_llm_response

# Translate the flavors in ice_cream_flavors to Spanish
ice_cream_flavors = ["Vanilla", "Strawberry"]

for flavor in ice_cream_flavors:
    prompt = f"""For the ice cream flavor listed below,
    Translate each flavor in spanish
    
    Flavor: {flavor}
    
    """
    ### --------------- ###
    print_llm_response(prompt)
# This prints
'''
____________________________________________________________________________________________________
Vanilla in Spanish is "Vainilla."
____________________________________________________________________________________________________


____________________________________________________________________________________________________
Strawberry in Spanish is "fresa."
____________________________________________________________________________________________________

Using dictionaries to complete high priority tasks using AI

from helper_functions import print_llm_response, get_llm_response
#task example, large list not ordered by priority. Want to prioritize
list_of_tasks = [
    "Compose a brief email to my boss explaining that I will be late for tomorrow's meeting.",
    "Write a birthday poem for Otto, celebrating his 28th birthday.",
    "Write a 300-word review of the movie 'The Arrival'.",
    "Draft a thank-you note for my neighbor Dapinder who helped water my plants while I was on vacation.",
    "Create an outline for a presentation on the benefits of remote work."
]
#instead of that unorganized large list, divide tasks by priority
high_priority_tasks = [
    "Compose a brief email to my boss explaining that I will be late for tomorrow's meeting.",
    "Create an outline for a presentation on the benefits of remote work."
]

medium_priority_tasks = [
    "Write a birthday poem for Otto, celebrating his 28th birthday.",
    "Draft a thank-you note for my neighbor Dapinder who helped water my plants while I was on vacation."
]

low_priority_tasks = [
    "Write a 300-word review of the movie 'The Arrival'."
]
#create dictionary with all tasks
#dictionaries can contain lists!
prioritized_tasks = {
    "high_priority": high_priority_tasks,
    "medium_priority": medium_priority_tasks,
    "low_priority": low_priority_tasks
}
#complete high priority tasks 
for task in prioritized_tasks["high_priority"]:
    print_llm_response(task)

Customizing recipes with lists, dictionaries and AI

# Update the following dictionary 
# with your own preferences 

from helper_functions import print_llm_response, get_llm_response

my_food_preferences = {
        "dietary_restrictions": ["no spicy food"], #List with dietary restrictions
        "favorite_ingredients": ["carrots", "olives", "tomatoes", "chicken", "fish"], #List with top three favorite ingredients
        "experience_level": "intermediate", #Experience level as a chef
        "maximum_spice_level": 0 #Spice level in a scale from 1 to 10
}

print(my_food_preferences)

prompt = f"""Please suggest a recipe that tries to include 
the following ingredients: 
{my_food_preferences["favorite_ingredients"]}.
The recipe should adhere to the following dietary restrictions:
{my_food_preferences["dietary_restrictions"]}.
The difficulty of the recipe should be: 
{my_food_preferences["experience_level"]}
The maximum spice level on a scale of 10 should be: 
{my_food_preferences["maximum_spice_level"]} 
Provide a detailed description of the recipe.
"""

print_llm_response(prompt)

Helping AI make decisions

from helper_functions import print_llm_response
# Go through the list of tasks if a task from the list takes more than 15 minutes we can do it
task_list = [
    {
        "description": "Compose a brief email to my boss explaining that I will be late for next week's meeting.",
        "time_to_complete": 3
    },
    {
        "description": "Create an outline for a presentation on the benefits of remote work.",
        "time_to_complete": 60
    },
    {
        "description": "Write a 300-word review of the movie 'The Arrival'.",
        "time_to_complete": 30
    },
    {
        "description": "Create a shopping list for tofu and olive stir fry.",
        "time_to_complete": 5
    }
]

for task in task_list:
    if task["time_to_complete"] >= 15:
        task_to_do = task["description"]
        print_llm_response(task_to_do)

Using files in python and AI

from helper_functions import get_llm_response
from IPython.display import display, Markdown

# We open a file with an email in it
f = open("email.txt", "r")
email = f.read()
f.close()

# We ask the AI to extract the bullet points from the email
prompt = f"""Extract bullet points from the following email. 
Include the sender information. 

Email:
{email}"""

print(prompt)
bullet_points = get_llm_response(prompt)
print(bullet_points)

# Print in Markdown format
display(Markdown(bullet_points))

# Here is a prompt to identify all of the countries mentioned 
# in the email
prompt = f"""Make a list of all the countries mentioned in the email

Email:
{email}
"""

countries = get_llm_response(prompt)
print(countries)

# Other example get a list of activities the person mentioned in the email
prompt = f"""Make a list of all the activies that Daniel did and mentioned in the email

Email:

"""

activities = get_llm_response(prompt)
print(activities)

Loading and using your own data

from helper_functions import upload_txt_file, list_files_in_directory, print_llm_response

# list out the files in the current working directory:
list_files_in_directory()

# Using AI to determine if a file is relevant for a specific context
# List of the journal files
files = ["cape_town.txt", "madrid.txt", "rio_de_janeiro.txt", "sydney.txt", "tokyo.txt"]
for file in files:
    # Read journal file for the city
    f = open(file, "r")
    journal = f.read()
    f.close()

    # Create prompt
    prompt = f"""Respond with "Relevant" or "Not relevant": 
    the journal describes restaurants and their specialties.

# We would print the reponse like this
display(HTML(html_response))

# We could also save this to an html file
f = open("highlighted_text.html", 'w') 
f.write(html_response) 
f.close()

Work with csv files and IA

# Imports
from helper_functions import get_llm_response, print_llm_response, display_table
from IPython.display import Markdown
import csv

f = open("itinerary.csv", 'r')

# Read data from the file
csv_reader = csv.DictReader(f)

for trip_stop in itinerary:
    # For example: get the destinations located in "Japan"
    if trip_stop["Country"] == "Japan":

# Using AI to suggest trip activities
# Select the first destination from the itinerary list
trip_stop = itinerary[0]

Please create a detailed daily itinerary."""

print(prompt)

# Use Markdown to display the LLM response nicely

# Store the LLM response
response = get_llm_response(prompt)

# Print in Markdown format
display(Markdown(response))

Work with functions

from helper_functions import print_llm_response
from IPython.display import Markdown, display

# create a function to print the journal
def print_journal(file):
