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.
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.
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
