Which method or operator can be used to concatenate lists?

Question

BlackTom AI · Accepted Answer

To tackle the question, consider what operation combines two lists into a single sequence.
Option 'concat': While some languages have a function named concat, in many common programming contexts lists are not concatenated via a dedicated 'concat' operator; the wording is ambiguous and not universally recognized as the list-concatenation operator.
Option '*': In several languages, the asterisk denotes repetition or multiplication, and when applied to lists it typically repeats the list rather than concatenating two lists. This means it does not reliably join two lists into one combined list.
Option '+': This is the standard operator used to concatenate lists in languages like Python, where applying '+' to two lists produces a new list containing the elements of both in order. It directly represents the join of two sequences, fulfilling the concatenation operation.
Option '%': The percent symbol is commonly used for modulo operations or string formatting in various languages, and it does not serve as a list-joining operator.
Taking all options together, '+' is the appropriate choice for list concatenation in typical programming contexts, whereas the other options either refer to different concepts or are not universally accepted as list-concatenation operators.
