Definite iteration is iteration a fixed number of times, usually looping through some kind of like a list. Python implements definite iteration using loops. It consists of three parts: Initialization, where a variable is declared and initialized with an value; Condition, where a condition is checked before each iteration; and Update, where the variable is updated after each iteration. An example of a for loop is: for i in range(5): print("i is currently ", i). The loop repeats 5 times, each time incrementing i by one - 0, 1, 2, 3, .
The loop checks to see if there is still a left in the range. If there are no numbers remaining in the range, the loop . The range() function in Python is used to generate a sequence of numbers and it returns a range object, which represents a sequence of numbers within a specified range. The range object can be used in for loops or converted to other iterable data types like . The syntax of the range function is range(start, stop, step). The start is optional and defaults to 0; the stop is required and does not include this number in the , while the step is optional and defaults to 1.
For example, in the code: for i in range(0, 10, 2): print(i), the range function generates a sequence of numbers from 0 to 10 (exclusive) with a size of 2. Each number in the sequence is printed using a for loop, resulting in the output of 0, 2, 4, 6, and . This demonstrates how the range function can effectively control the flow of iteration using for loops in Python programming.
