**Common questions beginner asks about Python for Data Science?**

**1. Do I need to learn coding to learn Python?**

If you are totally new to programming, no need to get intimidated by learning a whole new language.

Python is a very easy language to learn:

- It does not have a complicated syntax and understanding Python is very intuitive.
- You don’t need to be skilled in coding for getting started in Python.

This course is for beginners we will start right from the foundations to performing data analysis tasks in Python.

**2. I am familiar with other Programming Languages like Java/C++. Will this course help me to migrate to Python?**

Do you know that Python is essentially a wrapper on C? That is what makes it fast and easy to understand!

- Though Python has recently become popular amongst Data Scientists, it was originally a general-purpose language.
- Python is still object-oriented and follows many of the paradigms that Java does.
- So if you are familiar with the concepts of programming, you can migrate to Python easily with this course.

**3. How much Python do I need to know to enter Data Science?**

- Though Python has hundreds of libraries and many more functionalities, you don’t need to know all of them for learning Data Science
- Rather than becoming an expert in the entire language, you would need to just be acquainted with the basic syntax of Python.
- We will also cover the most popular libraries used by Data Scientists and which you would be using too as a future Data Scientist!

**4. What if I don’t have Python installed on my system?**

One of the best things about Python is the wide variety of platform that support writing it.

We will provide easy to follow instructions to work with Python using Anaconda, an extremely popular package manager platform. No matter what Operating System you are using, we have you covered with guides for all of them.

**5. What are the most popular open-source libraries that Python supports?**

- pandas, numpy, scipy, matlplotlib, seaborn are used for Data Science and Data Analysis
- scikit-learn, tensorflow, keras are used for basic and advanced machine learning
- libraries for deep learning like OpenCV(Computer Vision), NLTK(Natural Language Processing)

**6. Will I be able to apply what I have learnt here to machine learning and data science projects?**

- The Python for Data Science course is designed to help you completely understand Python and start using it immediately for Data Science projects.
- With regular assignments, quizzes and hands-on projects, you will be full equipped with the essential data science skillsets.
