Remove empty strings from a list of strings

🧹 How to Remove Empty Strings from a List of Strings in Python 🐍

Have you ever found yourself with a messy list full of empty strings that you just want to get rid of? Well, fear not! Today we're going to explore how to remove these pesky empty strings from a list of strings in Python. 🧻

The Problem 😫

Our fellow Pythonista is facing the following problem: they want to remove all empty strings from a list of strings. 🤔

Here's what their initial idea looks like:

while '' in str_list:
    str_list.remove('')

While this approach technically works, it might not be the most elegant or "Pythonic" solution. Thankfully, there are more efficient ways to tackle this issue. 💡

The Pythonic Solution 🐍

Python provides a variety of tools to make your code more concise and readable. One way to remove empty strings from a list is to use a list comprehension. Here's how it works:

str_list = [s for s in str_list if s]

Let's break it down:

1. We iterate over each string s in str_list.

2. We keep the string s if it evaluates to True (i.e., it's not empty).

3. The resulting strings are collected and stored back into str_list.

Voilà! 🎉 Using a list comprehension, we've successfully removed the empty strings from our list in a more elegant and Pythonic manner.

The Final Call-to-Action 📣
