Python programming language: loops

In the Python programming language (also “Python” or “Python”), there are several ways to loop some action. The main tools for implementing any kind of iteration in Python are while and for loops. The while loop is more universal than for, so it runs slower. However, this does not mean that he is better! The for loop is used much more often, because it can be used to implement the most complex tasks for creating multi-level and multi-conditional programs.
