The syntax of the Python programming language is the set of rules that defines how a. The ordered sequential types are lists (dynamic arrays), tuples, and strings. n: n*n for n in range(5) } # dict comprehension {0: 0, 1: 1, 2: 4, 3: 9, 4: 16}.
With datetime, a module, we parse strings containing dates. Python program that uses strptime from datetime import datetime # Input string. s = "August 16, 2012" Python program that sorts date list from datetime import date, timedelta. A list in Python is an ordered group of items (or elements). and list elements Python has a few, very useful, built-in data structures that you will see used everywhere. The indices effectively mark the gaps between the items in the string or list. x[2] = 16 >>> x [1,4,16,.new end of list.] >>> x[2:3] = [9,16,25] [1,4,9, 1625
