How to Generate Float Ranges in Python?

Float Equivalents for range() in Python

The Python range() function operates on integers, but is there a comparable function for floats? By default, range() produces a range of integers, even if the start and stop parameters are floats.

Consider the following example:

<code class="python">>>> range(0.5, 5, 1.5)
[0, 1, 2, 3, 4]</code>

The output excludes the starting float (0.5) because the step size is an integer (1.5).

To retrieve a range of floats, you can employ one of the following approaches:

1. List Comprehension:

<code class="python">[x / 10.0 for x in range(5, 50, 15)]</code>

This method creates a list of floats by dividing each integer in the range by 10.0.

2. Lambda Function and map():

<code class="python">map(lambda x: x / 10.0, range(5, 50, 15))</code>

This method combines a lambda function with the map() function. The lambda function converts each integer in the range to a float by dividing it by 10.0.
