## Slide 0

This is a test to see how we can make Python work within RStudio

## Slide 1

This is a test to run python code. Let's test if Python works:

The R package `reticulate` allows R to work with Python.

```{r}

library(reticulate)

```

We can then check which python is running:

```{python}

import sys

print("User Current Version:-", sys.version)

```

## Test 2

A simple Python script to check divisibility by 3.

```{python eval=TRUE}

num = 16

if num % 3 == 0:

  print("is divisible by 3")

else:

  print("is not divisible by 3")

```

## SillyNameGenerator-gpt.py {.smaller}

Testing a Python script generated by ChatGPT. It requires the `termcolor` package that can be installed by `pip` or `pip3`. Run if necessary.

```{bash}

# python3 -V

# pip3 install termcolor

```

Note on code next slide: The interactivity has been disabled otherwise the compilation of slides hangs, waiting for user input!

## Continued - SillyNameGenerator-gpt.py {.smaller}

```{python eval=FALSE}

import random

from termcolor import colored

# Define lists of first names and surnames

first_names = ['John', 'Mary', 'David', 'Emily', 'William']

surnames = ['Smith', 'Johnson', 'Brown', 'Taylor', 'Davis']

# Define a function to play the game

def play_game():

    # Choose a first name at random and assign it to a variable

    first_name = random.choice(first_names)

    # Choose a surname at random and assign it to a variable

    surname = random.choice(surnames)

    # Print the names to the screen in order and in red font

    print(colored(f"{first_name} {surname}", 'red'))

    # Ask the user to quit or play again

    choice = input("Do you want to play again? (y/n)")

    # If user plays again, call the play_game function again

    if choice == 'y':

        play_game()

# Call the play_game function to start the game

play_game()

```
