How to Create a Floating-Point Range Sequence in Python?

Floating-Point Range Equivalent in Python

Python's range() function doesn't natively support generating sequences of floating-point numbers. This can be a limitation when working with decimal values.

Consider the following example:

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

As you can see, the resulting sequence excludes the actual starting point of 0.5.

To overcome this, you can create a floating-point range using one of the following methods:

Using List Comprehension

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

This initializes a list with values ranging from 0.5 to 4.5 in increments of 0.5.

Using Lambda and Map

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

This creates a map object that applies the lambda function x / 10.0 to each value in the range, resulting in a similar sequence as the list comprehension.
