The code var.split accesses the .split method of the string stored in the variable var. This method can split the string into a list of substrings based on a delimiter.

However, var.split by itself does not execute the method—no parentheses are present. Therefore, it retrieves the split method as an object but does not actually perform the splitting operation.

If parentheses were added (e.g., var.split(delimiter)), it would split the string in var based on the specified delimiter. The default delimiter is any whitespace if none is provided.
