The Python Code:

import matplotlib.pyplot as plt
from matplotlib.widgets import Slider
import numpy as np


def wet_bulb_stull(T, RH):
  term1 = T * np.arctan(0.151977 * (RH + 8.313659) ** 0.5)
  term2 = np.arctan(T + RH)
  term3 = np.arctan(RH - 1.676331)
  term4 = 0.00391838 * (RH**1.5) * np.arctan(0.023101 * RH)
  return term1 + term2 - term3 + term4 - 4.686035


# Grid setup for background contours

  point.set_offsets([[rh, t]])

      f'Interactive Heat Stress Visualizer (Wet-Bulb: {tw:.1f}°C)',
      fontsize=14,
      fontweight='bold',
  )
  fig.canvas.draw_idle()


s_temp.on_changed(update)
s_rh.on_changed(update)

plt.show()

I am running this in PyCharm. The code is the work of Gemini AI!!

                                                                *     *     *

I copied the code to Notepad, saved it with a .py extension and now it opens like any other

shortcut on my dektop: with a double-click!
