This line of code reads through each row of a CSV file using the variable "reader" and creates a list called "rows". Each element in the list represents a row in the CSV file. The "for" loop iterates through each row and appends it to the list using a list comprehension.
Note: The variable "reader" is typically created using the "csv.reader()" function and takes in the CSV file as an argument.
