Using Python control statements, loops, and list comprehensions
Control statements are used for various tasks. For example, they’re used to filter data based on certain conditions, perform a calculation on each item in a list, iterate through rows in a dataframe, and more. Additionally, list comprehensions are widely used in data science as they provide efficiency and legibility. It’s often used in data cleaning and preprocessing tasks, feature engineering, and more.
Control statements in Python allow you to control the flow of your program’s execution based on certain conditions or loops. The main types of control statements are conditional statements (such as if
, elif
, and else
) and loop statements (such as for
and while
).
Meanwhile, list comprehensions are a sort of short-hand approach to writing loop statements. More specifically, they are a shorter, more concise syntax for creating a list based on the values of an existing list.
