The range() function in Python is used to generate a sequence of numbers. The most common use of it is to iterate sequences on a sequence of numbers using Python loops.
The range() function takes three arguments:
start: The starting number of the sequence.stop: The ending number of the sequence.step: The step size. The default step size is 1.
For example, the following code will generate a sequence of numbers from 0 to 9:
Python
for i in range(10):
  print(i)
The output of the code is:
Code snippet
0
1
2
3
4
5
6
7
8
9
The range() function can also be used to generate a sequence of numbers in reverse order. For example, the following code will generate a sequence of numbers from 9 to 0:
Python
for i in range(9, -1, -1):
  print(i)
The output of the code is:
Code snippet
9
8
7
6
5

The range() function is a very versatile function, and it can be used in a variety of ways. It is a valuable tool for any Python programmer to know.
Here are some additional things to keep in mind about the range() function:
The range() function does not actually create a list of numbers. It just generates a sequence of numbers.The range() function is a lazy function, which means that it does not actually generate all of the numbers in the sequence until they are needed.The range() function can be used with any iterable object, such as a list or a string.
