Is arr.__len__() the preferred way to get the length of an array in Python?

📝 Title: A Guide to Getting the Length of an Array in Python: Unveiling the Mystery of arr.__len__()

👋 Hey there, tech enthusiasts! 🤓

Have you ever wondered how to find the length of an array in Python? 🧐 Well, you're not alone! The question of whether arr.__len__() is the preferred way to get the length of an array has sparked curiosity among many Python developers. 🤔 Let's dive into this topic to clear any confusion and provide you with easy and practical solutions! 💪

🔍 Understanding the Issue

The first thing we need to address is the strange syntax of arr.__len__(). While technically it does provide the length of an array, it is not the preferred or recommended method. 🙅‍♀️ In fact, using the double underscore method (__len__()) directly is considered unconventional and goes against Python's best practices.

So why is this syntax even available? Well, it turns out, Python arrays are actually objects. When you access the length using arr.__len__(), you're directly calling the underlying method of the array object. However, this is not the Pythonic way of doing things! 🙅‍♂️

Let's explore the preferred and more intuitive methods to obtain the length of an array! 🚀

💡 Method 1: Using the len() Function

Python provides a built-in function called len() that returns the length of any iterable object, including arrays. 📏 This is the most common and recommended way to find the length of an array.

arr = [1, 2, 3, 4, 5]
length = len(arr)

print(length)  # Output: 5

Using the len() function is not only more concise and readable, but it also aligns with the Pythonic principles of simplicity and clarity. 🐍

💡 Method 2: Checking the len Attribute

Another approach to obtaining the array length is by directly accessing the len attribute of the array object. This method is less frequently used but worth mentioning.

arr = [1, 2, 3, 4, 5]
length = arr.__len__()

print(length)  # Output: 5

While this method gives the same result, it still falls into the category of "unpythonic" code. So, even though it is technically valid, it is strongly encouraged to use the len() function instead. 😎

📢 Take Action!

Now that you're armed with knowledge about the preferred ways to find the length of an array in Python, it's time to put it into practice! 🙌 Embrace the Pythonic way and start using the len() function to easily obtain the length of your arrays.
