The Python range() function will generate a sequence of numbers. For example, range(10) will generate numbers from 0 to 9 (10 numbers).

We can also define the start, stop, and step size as parameters and range() will be as follows:

range(start, stop, step size).
Step size defaults to 1 if not provided.
For loop example using range() function:

Let's take a look at an example:

for i in range(5):
 print("The number is", i)

Output:
The number is 0
The number is 1
The number is 2
The number is 3
The number is 4
