This was the first experiment I did in this session.
It's the standard FlashFill experiment.


The prompt:
'''
I want you to act as an expert in for example computer programming, mathematics, pattern recognition, induction logic programming, program synthesis and related topics. I will show you examples of inputs and corresponding outputs and you will generate Python3 code for generating the output from the input. Acknowledge with "OK.".
'''

There's the input
''''
Input: "Hans Gustavsson" Output: "hgustavsson.gmail.com"
Input: "Erik Lindemann" Output: "elindeman.gmail.com"
Input: "Håkan Kjellerstrand" Output: "hkjellerstrand.gmail.com"
Input: "Gary Marcus" Output: "gmarcus.gmail.com"
'''


GPT4 answered the following on the first try:
'''
Based on the provided input-output pairs, it seems the objective is to generate an email address with the following pattern:

- Take the first character of the first name (in lowercase).
- Add the full last name (in lowercase).
- Append ".gmail.com" to the end.
- Here's a Python function to implement this pattern:

[the program]

This code defines the generate_email function, which takes a name string and generates an email address following the described pattern. It then demonstrates the use of this function on the provided examples.
'''

And this is completely correct.

The Python program:
'''
def generate_email(name):
    first_name, last_name = name.split()
    email = f"{first_name[0].lower()}{last_name.lower()}.gmail.com"
    return email

input1 = "Hans Gustavsson"
output1 = generate_email(input1)
print(f"Output for input1: {output1}")

input2 = "Erik Lindemann"
output2 = generate_email(input2)
print(f"Output for input2: {output2}")

input3 = "Håkan Kjellerstrand"
output3 = generate_email(input3)
print(f"Output for input3: {output3}")

input4 = "Gary Marcus"
output4 = generate_email(input4)
print(f"Output for input4: {output4}")
"""

hakank:
'''
What would be the output of the input
"Erik Gustaf Geijer"
'''


GPT4:
'''
Based on the pattern established earlier, we can slightly modify the
generate_email function to handle names with a middle name. The email will
be generated using the first character of the first name, the full last
name, and then appending ".gmail.com" to the end.

python
Copy code
def generate_email_v2(name):
    name_parts = name.split()
    first_name, last_name = name_parts[0], name_parts[-1]
    email = f"{first_name[0].lower()}{last_name.lower()}.gmail.com"
    return email

input5 = "Erik Gustaf Geijer"
output5 = generate_email_v2(input5)
print(f"Output for input5: {output5}")

In this updated generate_email_v2 function, we split the name into parts
and then assign the first and last parts to first_name and last_name,
respectively. This allows us to handle names with middle names as well.
The output for the input "Erik Gustaf Geijer" would be "egeijer.gmail.com".
'''


hakank:
'''
Hmm, I would rather that the output was
eggeijer.gmail.com

Some other examples:

Input: "Anna-Karin Jessica Eriksson" Output: "akjeriksson.gmail.com"
Input: "Lena-Stine Ohlsson" Output: "lsohlsson.gmail.com"
'''


GPT4:
'''
Thank you for the clarification. Based on the new examples, it seems
the objective is to include the first letter of each part of the name
(except for the last name) in the email address. Here's the updated
Python function to handle these cases:

  [program]

In the generate_email_v3 function, we create the variable first_initials
by joining the first letter of each part of the name except for the
last name. The rest of the email generation follows the previous pattern.
This function should now generate the correct output for the provided examples.
'''

hakank:
'''
This was almost correct. Please note the following examples again.

Input: "Anna-Karin Jessica Eriksson" Output: "akjeriksson.gmail.com"
Input: "Lena-Stine Ohlsson" Output: "lsohlsson.gmail.com"

Please don't show the Python code unless I ask for it.
'''

GPT4:
'''
I apologize for the confusion. Based on the new examples, the objective is
to include the first letter of each part of the name (except for the last name)
in the email address. Additionally, if a part of the name contains a
hyphen, include the first letter of each hyphen-separated subpart.

For example:

"Anna-Karin Jessica Eriksson" would become "akjeriksson.gmail.com"
"Lena-Stine Ohlsson" would become "lsohlsson.gmail.com"

Please let me know if you would like to see the updated Python code.
