in Python, if k is an integer, equation k / 4 returns the integer part of k over 4, while in Sage, it returns a rational. How to work in Sage and change from result od divide from rational to like in Python ?

example: python

5 divide by 3 = 1

5 divide by 2 = 2

4 divide by 2 = 2

The Python behaviour you describe was that of Python 2, which is no longer current.

In Python 3:

>>> 5 / 3
1.6666666666666667
>>> 5 / 2
2.5
>>> 4 / 2
2.0

In Sage, if you want "floor division" (integer quotient without remainder), use // instead of /.

sage: 5 // 3
1
sage: 5 // 2
2
sage: 4 // 2
2
