range(x) returns a list of numbers from 0 to x - 1. >>> range(1) [0] >>> range(2) [0, 1] >>> range(3) [0, 1, 2] >>> range(4) [0, 1, 2, 3] for i in range(x): executes the body (which is print i in your first example) once for each element in the list returned by range(). i is used inside the body to refer to the “current” item of the list.

Python for i in range statement is for loop iterating for each element in the given range. In this tutorial, we have examples: for i in range(x), for i in range(x, y), for i in range(x, y, step)
10 sty 2024 · You can create ranges by calling range () with one, two, or three arguments, as the following examples show: Python. >>> list(range(5))[0, 1, 2, 3, 4]>>> list(range(1,7))[1, 2, 3, 4, 5, 6]>>> list(range(1,20,2))[1, 3, 5, 7, 9, 11, 13, 15, 17, 19] In each example, you use list () to explicitly list the individual elements of each range.
