Example text

Storage of elements of a sequence You can iterate through the elements of a sequence x having n elements starting at element x[0] and adding +1 each time x[1], x[2] ¼ x[n-1], and so on. You can also iterate from the end and subtract 1 each time: x[n-1], x[n-2] ¼ x[0]. Membership A common check is to determine whether a value exists in a sequence. For example: 'a' in 'track' 9 in [1,2,3,4,5,6] # True # False 'x' not in 'next' 'red' not in ['tan','pink'] # False # True Concatenation2 Two or more sequences can be added together to make longer sequences.

Here are some examples: >>> l = [1,2,3,4,5] >>> d = {1:'one',2:'two',3:'three'} >>> lenDictList(l) 5 2 All open source or free-to-use libraries come with a health warning, but if you see many references to a library on programmer web sites and in books, you can be reasonably confident that it works. 31 CHAPTER 3 ■ PROGRAM STRUCTURE >>> lenDictList(d) 3 >>> lenDictList(34) -1 Note that the real len() handles any sequence including tuples and strings and does better error-handling. This is a much oversimplified version.

0 Sequences: Strings, Lists, and Tuples So far, we have looked at variables that hold a single value. A sequence is a variable that holds multiple values as an array. Each element can be addressed by its position in the sequence as an offset from the first element. The three types of sequence are as follows: • Strings: A sequence of characters that together form a text string. • Lists: A sequence of values where each value can be accessed using an offset from the first entry in the list. • Tuples: A sequence of values, very much like a list, but the entries in a tuple are immutable; they cannot be changed.
