Does range() not evaluate its argument every time?

Question

l is passed as an argument to range function whose value is modified inside for loop, but the loop is going for 10 times

Answer 1

No, the for loop evaluates the iterable expression just once.

range() is called once, and the for loop then iterates over the result.

Quoting from the for statement documentation:

The expression list is evaluated once; it should yield an iterable object.

emphasis mine.
