![]() The return value is a sequence of numbers from the given start to stop index. step: (optional).The step value is the number by which the next number is range has to be incremented, by default, it is 1.The last value will be always 1 less than the stop value. It is a mandatory input to range function. stop: The stop index decides the value at which the range function has to stop.start: (optional) The start index is an integer, and if not given, the default value is 0.Example: Get even numbers using range().Using floating numbers in Python range(). ![]() Reverse Range: Decrementing the values using negative step.Incrementing the values in range using a positive step.The Python range()is a very useful command and mostly used when you have to iterate using for loop. In case the start index is not given, the index is considered as 0, and it will increment the value by 1 till the stop index.įor example range(5) will output you values 0,1,2,3,4. Python range() is a built-in function available with Python from Python(3.x), and it gives a sequence of numbers based on the start and stop index given.
