Variables On Python: Why?

Question

Okay. . . Okay, why do we use 'del' why don't we just delete? For example:
' Lemons = 90
Apples = 4
del bar
Apples = 8
print(Lemons * Apples)
360 '

Why not just delete the first Apple variable?

Answer 1

If this is from course content it's giving you the example of values can be changed. Also if you were making this code, you would just have one apple variable defined to be more pythonic.
