Every line of code is executed in the order that it’s written or in the order that functions are called, with possible repetitions inside loops. In this course, you’ll learn how to use conditional logic to write programs that perform different actions based on different conditions. Paired with functions and loops, conditional logic allows you to write complex programs that can handle […]

Data scientists process text to extract data and perform tasks like sentiment analysis, which can help identify and classify opinions in a body of text.
