From collections import namedtuple Animal = namedtuple ( 'Animal', 'name age type' ) perry = Animal ( name = 'perry', age = 31, type = 'cat' ) print ( perry ) # Output: Animal(name='perry', age=31, type='cat') print ( perry. Name ) # Output: 'perry' You can now see that we can access members of a tuple just by their name using a. TOra is a Toolkit for Oracle which aims to help the DBA or developer of database applications. Features PL/SQL debugger, SQL worksheet with syntax highlighting, DB browser and a full set of DBA tools. TOra also includes support for MySQL and Postgres. Let’s dissect it a little more. A named tuple has two required arguments. They are the tuple name and the tuple field_names. In the above example our tuple name was ‘Animal’ and the tuple field_names were ‘name’, ‘age’ and ‘type’. Namedtuple makes your tuples self-document. You can easily understand what is going on by having a quick glance at your code. And as you are not bound to use integer indexes to access members of a tuple, it makes it more easy to maintain your code. Moreover, as `namedtuple` instances do not have per-instance dictionaries, they are lightweight and require no more memory than regular tuples. This makes them faster than dictionaries. However, do remember that as with tuples, attributes in namedtuples are immutable. It means that this would not work. Enum.Enum (Python 3.4+) Another useful collection is the enum object. It is available in the enum module, in Python 3.4 and up (also available as a backport in PyPI named enum34.) Enums () are basically a way to organize various things. Let’s consider the Animal namedtuple from the last example. It had a type field. The problem is, the type was a string. This poses some problems for us. What if the user types in Cat because they held the Shift key? Enumerations can help us avoid this problem, by not using strings. Consider this example. From collections import namedtuple from enum import Enum class Species ( Enum ): cat = 1 dog = 2 horse = 3 aardvark = 4 butterfly = 5 owl = 6 platypus = 7 dragon = 8 unicorn = 9 # The list goes on and on. # But we don't really care about age, so we can use an alias. Kitten = 1 puppy = 2 Animal = namedtuple ( 'Animal', 'name age type' ) perry = Animal ( name = 'Perry', age = 31, type = Species. A2: I am really sorry for this. Fgtech v53 crackle. Cat ) drogon = Animal ( name = 'Drogon', age = 4, type = Species. Dragon ) tom = Animal ( name = 'Tom', age = 75, type = Species. Cat ) charlie = Animal ( name = 'Charlie', age = 2, type = Species. Kitten ) # And now, some tests. Type True >>> charlie. Download Plastic Memories Sub Indo BD dalam format Mkv 480p, Mkv 720p, Mp4 720p, Mp4 480p, Mp4 360p, Mp4 240p dan BATCH.

Type This is much less error-prone. We have to be specific, and we should use only the enumeration to name types. There are three ways to access enumeration members. For example, all three methods will get you the value for cat. Installing Python Unlike most Unix systems and services, Windows does not require Python natively and thus does not pre-install a version of Python. However, the CPython team has compiled Windows installers (MSI packages) with every for many years. With ongoing development of Python, some platforms that used to be supported earlier are no longer supported (due to the lack of users or developers). Check for details on all unsupported platforms. • DOS and Windows 3.x are deprecated since Python 2.0 and code specific to these systems was removed in Python 2.1. • Up to 2.5, Python was still compatible with Windows 95, 98 and ME (but already raised a deprecation warning on installation). For Python 2.6 (and all following releases), this support was dropped and new releases are just expected to work on the Windows NT family. • is still supported. • The installer offers to install the Python interpreter as well (cf., ) See for detailed information about platforms with precompiled installers. Executing scripts Python scripts (files with the extension.py) will be executed by python.exe by default. This executable opens a terminal, which stays open even if the program uses a GUI.
