The continue statement rejects all the remaining statements in the current iteration of the loop and moves the control back to the top of the loop. The continue statement can be used in both while and for loops.Your “go back a step” operation is what’s commonly referred to as a GoTo, probably the most hated operation in any programming language. It is not supported in Python, you must use other methods like loops. You go back by using loops, like those while loops you have.In Python, the break statement provides you with the opportunity to exit out of a loop when an external condition is triggered. You’ll put the break statement within the block of code under your loop statement, usually after a conditional if statement.

reverse() actually reverses the elements in the container. reversed() doesn’t actually reverse anything, it merely returns an object that can be used to iterate over the container’s elements in reverse order. If that’s what you need, it’s often faster than actually reversing the elements.
