Example text
Python has one collection type in its standard library that does not hold object references; instead, it holds numbers of a specified type. This is the array type and it is used in situations where large numbers of numbers need to be stored and processed as efficiently as possible. In this section, we will look at Python’s built-in collection types. Tuples String slicing 22 ☞ A tuple is an ordered sequence of zero or more object references. Like strings (and as we will see shortly, like lists), tuples support sequence functions such as len() as well as the same slicing syntax that we saw earlier.
5 introduced a conditional expression. It is a kind of if statement that can be used in expressions, and it is equivalent to the ternary operators used by some other languages. The Python syntax is quite different from C++’s and Java’s, which use ? ★ Looping Python provides two loop constructs. = 0: print count, count -= 1 This will print “10 9 8 7 6 5 4 3 2 1”—all on one line, due to the print statement’s trailing comma. Notice that we must have a colon before the indented suite. Loops can be broken out of prematurely, using the break statement.
In this book, we will follow the official Python guidelines. = but is deprecated Identity is, is not These are used to determine if two object references refer to the same underlying object Membership in, not in These are used on lists, dictionaries, and strings, as we saw in Chapter 1 Logical not, and, or Both and and or short-circuit; the bit-wise equivalents are: ~ (not), & (and), | (or), and ^ (xor) if x > 0: print x In this case, the suite is just one statement (print x). In general, a suite is a single statement, or an indented block of statements (which themselves may contain nested suites), or the keyword pass which does absolutely nothing.
