Fortunately, there's a better way: iterating over the list with a loop. Although pseudocode is a syntax-free description of an algorithm, it must provide a full description of the algorithms logic so that moving from pseudocode to implementation is merely a task of translating each line into code using the syntax of any given programming language. You're probably better off just letting your pseudocode be long and explicit, rather than sacrificing clarity for brevity. Set cat1 to empty list Is there any known 80-bit collision attack? That line of code specifies an index of 4 and a number to remove of 1, so it removes a single item at index 4.
