6. Frequently Asked Questions (FAQs)

What’s the difference between Python 2 and Python 3?

Some of the changes made in Python 3 are not compatible with Python 2. For example, print as a function and integer division that returns float values are not backward compatible. Because of this, Python 2 will no longer be available after January 1, 2020. Instead, Python 3 is suggested.

How long does it take to learn Python?

A lot of things affect how long it takes to learn Python, like how much time you spend studying and practicing. Beginners who have never programmed before might need to learn consistently for a few months before they hit a level of comfort.

Can I build websites with Python?

Yes, many people use Python to build websites. Frameworks like Django and Flask make it simple to create web apps that are both strong and scalable.

Is Python good for working with data?

Of course. Python is a top language for data science because it has strong libraries like pandas, NumPy, and sci-kit-learn that make it easy to work with data, analyze it, and teach machines new things.
