Introduction to Python
If you don't want to iterate over elements but want to iterate over indexes, then you need to learn the range()
function.
range()
returns a range
object representing a set of numbers. This function can receive 1, 2, or 3 arguments (positive numbers).
Suppose the function receives only one argument, n
. In that case, it will return all the integers from 0
to n
(not including n
itself). For instance, range(5)
will generate integers from 0
to 4
.
If the function receives two arguments, n
and m
, it will return all the integers from n
to m
(not including m
).
For instance, range(5, 10)
will return integers from 5
to 9
.
If the function receives three arguments, n
, m
, and s
, it will return integers from n
to m
with the step of s
(not including m
).
For example, range(10, 30, 5)
will return integers 10, 15, 20, 25
.
