Code Repetition in Python

Code repetition is a common programming technique used to perform a task multiple times. In Python, there are several ways to achieve this, such as for loops, while loops, and list comprehensions. Here, we will discuss one of the simpler ways to perform code repetition in Python: the range() function.

The range() function generates a sequence of numbers, starting from 0 by default and increments by 1 (by default), and stops before a specified number. To use the range() function, we specify the number that the sequence should stop before. In the example below, we'll use the range() function to print the numbers from 0 to 9:

for i in range(10):
    print(i)

The output will be:

0
1
2
3
4
5
6
7
8
9

The range() function can also be used with two arguments. The first argument will be the starting number and the second argument will be the stopping number. In the example below, we'll use the range() function to print the numbers from 5 to 9:

for i in range(5, 10):
    print(i)

The output will be:

5
6
7
8
9

The range() function can also be used with three arguments. The first argument will be the starting number, the second argument will be the stopping number, and the third argument will be the step size. The step size is the amount by which the sequence will increment after each iteration. In the example below, we'll use the range() function to print the numbers from 0 to 8 with a step size of 2:

for i in range(0, 10, 2):
    print(i)

The output will be:

0
2
4
6
8

The range() function is a simple and effective way to perform code repetition in Python. It can be used with one, two, or three arguments, allowing for a wide range of possibilities.
