How to Generate a Random Number within a Float Range

Question:

How can you generate a random number between two float values using the Python standard library?

Answer:

Unlike random.randrange(), which only accepts integer arguments, Python provides the random.uniform() function specifically designed to return a float value within a specified range.

Usage:

<code class="python">>>> import random
>>> random.uniform(1.5, 1.9)
1.8733202628557872</code>

Syntax:

<code class="python">random.uniform(a, b)</code>

where:

• a: The lower bound of the range (inclusive)
• b: The upper bound of the range (exclusive)

The random.uniform() function will generate a random float within the half-open range [a, b). For example, the code above will generate a random number between 1.5 and 1.9, inclusive of 1.5 but exclusive of 1.9.
