Unlock the Power of Python’s range() Function

When it comes to generating sequences of numbers in Python, the range() function is a game-changer. By default, this versatile function produces a sequence that starts at 0, increments by 1, and stops just shy of the specified number.

Customizing Your Sequence

But what if you need more control over your sequence? Fear not! The range() function has got you covered. With optional start and step arguments, you can tailor your sequence to fit your needs. Want to start at 5 and increment by 2? No problem! The range() function makes it easy.

Example Output: Seeing is Believing

Let’s take a look at some examples to see the range() function in action. In our first example, we’ll convert the range sequence to a list:

print(list(range(10))) # Output: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Next, we’ll specify a start value:

print(list(range(3, 10))) # Output: [3, 4, 5, 6, 7, 8, 9]

And finally, we’ll add a step value to the mix:

print(list(range(0, 20, 2))) # Output: [0, 2, 4, 6, 8, 10, 12, 14, 16, 18]

range() in Action: For Loops

So, how can you put the range() function to use in your code? One common application is in for loops, where it helps you iterate a certain number of times. Here’s an example:
“`
for i in range(5):
print(i)

Output: 0, 1, 2, 3, 4

“
With therange()` function, the possibilities are endless!
