20 Aug 2013 In a nutshell, it generates a list of numbers, which is generally used to iterate over with for loops. There.s many use cases. Often you will want to. In order to facilitate that, we.re going to learn about lists---a simple Python Once you.ve created a list and put values in it, you can get values back out of the list. Instead, the Python interpreter gave us a `generator object. In both cases (for loop as well as `list.), iteration stops when the StopIteration exception is raised.
12 Feb 2013 Coming from another language you might find it natural to create a counter and increment it to iterate over a list in Python. my_list = [17, 23, 47. 24 Apr 2012 The for loop is Python.s versatile swiss-army-knife iteration tool. Here we make a list of the values returned by f for each value in the iterable.

Python supports a concept called "list comprehensions". The interesting thing is that we first build a list of non-prime numbers, using a single list comprehension, a single statement (without the need for the temporary variable " noprimes ").

Create a file called example.sage with the following content: print "Hello. Some built-in Python types include strings, lists, tuples, ints and floats, as illustrated: sage: s. A common idiom is to iterate through the pairs in a dictionary: sage: d. In Python, for loops make this use case simple and easy by allowing you to At each iteration of the loop, the next element of the list pets is assigned to the.
