Course FAQ
Course FAQ
Is Python good for data science?

Yes! Python's robust libraries are ideal for manipulating data and it is a relatively easy language to learn for data analyst beginners!

Is Python better than R for data science?

Python and R are both great programming languages geared towards data science. However, Python is often easier for beginners, and is a more general purpose language with easy to read syntax. Python is better for raw data scraping, while R is more useful in analyzing already scrubbed data.

Will we be using Python libraries?

Yes. We will go over various standard Python libraries such as NumPy, Scikit-Learn, Pandas, Pickle, Matplotlib, and Flask to help with extracting, cleaning, and processing data, and building machine learning models.

What is data science with Python?

Simply put, it is a combination of statistical and machine learning techniques through the use of Python programming to help analyze and interpret data.

Are there prerequisites to this course?

Some previous exposure to Python or its libraries may come in handy, but is not required. Just come with an interest in data science.

Why learn data science?

Data science is a super popular field these days. Through data science we can find meaningful and valuable insights, and provide data-driven evidence to help organizations be more efficient and successful.
