Fix the python output in "Floating Point Numbers" section in "Python Fortran Rosetta Stone" page

Fixed the Python output in the "Floating Point Numbers" section in the explanatory notes.

[Zhou-Jiangcheng]

The result in Python cell, in line 4
f = float(1 / 2) # 0.0
seems wrong in Python 3.11, numpy 1.26.4. It should be 0.5.
And I also tried float32(1/2), it returns the same result.

Yes, it was correct in Python 2, but for Python 3 the behavior of / for two ints changed.
