Record Python concat function usage

In Python, the concat() function can be used to connect two or more sequences (such as lists or tuples). Its syntax is as follows:

 new_ sequence = concat(sequence1, sequence2, ..., sequenceN)

Where sequence1 to sequenceN are the sequences to be connected. These sequences can be lists, tuples, or other iterable objects. The concat() function returns a new sequence containing the elements of all sequences passed to the function in sequential concatenation.

Here is an example:

 list1 = [1, 2, 3] list2 = [4, 5, 6] list3 = [7, 8, 9] result = concat(list1, list2, list3) print(result)

Output results:

 [1, 2, 3, 4, 5, 6, 7, 8, 9]

In this example, we create three lists list1, list2 and list3, and then use the concat() function to connect them into a new list result. Note that the concat() function does not modify the original sequence, but returns a new sequence.
