Python Range Attributes

Range Attributes

In Python, a range object has following three attributes or properties.

  • start
  • stop
  • step

The following is a screenshot of the range class definition from Python core file builtins.pyi, with the above mentioned properties.

Python Range Attributes or Properties

Now, let us have a look at some example programs, where we take a range object and read these attribute values.

Examples

1. Print the properties of a range defined with start and stop

In the following program, we take a range defined by a specific start and stop values. And then we read the three properties and print them to standard output.

Python Program

myrange = range(0, 5)

start = myrange.start
stop = myrange.stop
step = myrange.step

print(f'Start : {start}')
print(f'Stop  : {stop}')
print(f'Step  : {step}')
Run Code Copy

Output

Start : 0
Stop  : 5
Step  : 1

The step value is 1 because if we do not mention a step value when defining a range object, the default step value would be 1.

2. Print the properties of a range defined with start, stop, and step

In the following program, we take a range defined by a specific start and stop values. And then we read the three properties and print them to standard output.

Python Program

myrange = range(0, 20, 3)

start = myrange.start
stop = myrange.stop
step = myrange.step

print(f'Start : {start}')
print(f'Stop  : {stop}')
print(f'Step  : {step}')
Run Code Copy

Output

Start : 0
Stop  : 20
Step  : 3

Summary

In this tutorial of Python Ranges, we learned how to read the properties/attributes of a range object.
