We'll also provide some practical examples of how you can use Python 3.7 to build your own games, whether you're a seasoned developer or just starting out.
So if you're looking for a new programming language to help you take your coding game to the next level, download Python 3.7 today and get started!
What’s new in Python 3.7?
Python 3.7 has several new features that make it an exciting upgrade for developers. Here are some of the highlights:
Data Classes
Python 3.7 introduces a new way to create classes that are primarily used for storing data: data classes. Data classes are similar to namedtuple and attr but are built into the language. They allow you to define classes with default, non-default and required attributes with little code. With data classes, you can avoid creating complex class constructors and instead create instances of classes that can be compared to each other.
Context Variables
Context variables are a new type of variables in Python 3.7 that allow you to store variables that are local to a particular context, such as a function or a block of code. This makes it easy to share data between functions within a given context without having to rely on global variables.
Performance Improvements
Python 3.7 introduces several performance improvements. These include faster dictionary construction, faster Unicode string handling, and faster and more memory-efficient bytecode interpretation. In addition, the interpreter now uses less memory when running, which means you can run more programs on the same machine.
asyncio Enhancements
Asyncio, introduced in Python 3.4, is now more powerful in Python 3.7. The most significant enhancement is the addition of the create_task function, which allows you to quickly create tasks that can run in the background without blocking the main thread. The new loop.shutdown_asyncgens() method allows you to clean up any leftover asynchronous generators when your program exits.
Better Debugging Features
Python 3.7 makes it easier to debug code with several new features. The breakpoint() function introduces a standard way to enter the debugger. Improved exception handling, including new syntax for catching multiple exceptions and enhanced tracebacks, provides more insight into what's causing issues in your code.
Conclusion
Python 3.7 offers many exciting improvements for developers. With data classes, context variables, performance improvements, asyncio enhancements, and better debug features, Python 3.7 is sure to revamp your coding game.
Installing Python 3.7
Python 3.7 is the latest version of Python, and it comes with many new features and improvements, such as better support for data classes, faster performance, and improved handling of async and await keywords. In order to start coding with Python 3.7, you will need to install it on your computer.
Step 1: Download Python 3.7
To download Python 3.7, go to the official Python website and click on the "Downloads" link. Choose the appropriate version for your operating system, whether you're using Windows, macOS, or Linux. Once you've downloaded the installer, double-click on it to start the installation process.
Step 2: Install Python 3.7
Follow the installation wizard to install Python 3.7 on your computer. During the installation process, you may be asked to choose certain configuration options, such as whether to install Python for all users or just for your user account. The default options are usually sufficient for most users, but you can customize them if you prefer.
Step 3: Verify the Installation
Once the installation is complete, you can verify that Python 3.7 is installed by opening a command prompt and typing "python3.7" (without quotes). This should start the Python interpreter, and you should see a message indicating the version number of Python that you're running.
Congratulations, you've successfully installed Python 3.7 on your computer! You're now ready to start coding with the latest and greatest version of Python.
Python basics for new users
If you are new to Python, this section will provide an overview of the basics.Python is a high-level programming language that is used for a wide range of applications, including software development, system scripting, and web application building. It is an excellent language for beginners because of its ease of use and clear syntax.
Here are some key concepts to keep in mind as you begin your Python journey:
Variables
Variables are used to store data. In Python, you can create a variable simply by assigning a value to it. For example, you could create a variable called "x" and set its value to 5 like this:
x = 5
Data Types
Python supports several different data types, including integers, floating-point numbers, strings, lists, and dictionaries.
- Integers are whole numbers like 1, 2, 3, etc.
- Floating-point numbers are decimal numbers like 3.14 or 2.5.
- Strings are sequences of characters like "hello" or "world".
- Lists are collections of values that can be accessed using an index.
- Dictionaries are collections of key-value pairs.
Operators
Python uses a variety of operators to perform calculations and manipulate values. Here are a few examples:
- Addition:
3 + 5 - Subtraction:
10 - 7 - Multiplication:
5 * 2 - Division:
10 / 2 - Modulus (remainder):
18 % 5
Control Flow
Control flow refers to the order in which statements are executed in a program. In Python, you can use conditional statements like "if" and "else" to control the flow of your program. Here's an example:
x = 5
if x > 10:
print("x is greater than 10")
else:
print("x is not greater than 10")
Functions
Functions are reusable blocks of code that perform specific tasks. In Python, you can create a function using the "def" keyword. Here's an example:
def say_hello(name):
print("Hello, " + name + "!")
say_hello("John")
This will output:
Hello, John!
Conclusion
This is just a brief introduction to some of the key concepts in Python. As you continue to work with this language, you'll learn more advanced topics like object-oriented programming, error handling, and data analysis. With its clear syntax and ease of use, Python is a great language for beginners to learn programming.
Advanced coding techniques in Python 3.7
Python 3.7 is a powerful programming language that can be used for various applications such as web development, data analysis, and machine learning. It offers new and improved features which make it easier to write code that is clean, concise, and efficient.
If you're looking to take your coding skills to the next level, here are some that you can use:
List Comprehensions
List comprehensions are a concise way of defining a new list by transforming or filtering an existing iterable. They allow you to create a new list with just one line of code. Here's an example:
# Create a new list with numbers from 1 to 10 squared
squares = [i**2 for i in range(1,11)]
print(squares)
Output:
[1, 4, 9, 16, 25, 36, 49, 64, 81, 100]
Using Decorators
Decorators are a powerful feature of Python that allows you to modify or enhance the behavior of functions or classes. They are a way of wrapping a function with another function that can add functionality to it. Here's an example:
# Define a decorator
def square_decorator(func):
def inner(n):
result = func(n)
return result**2
return inner
# Define a function to be decorated
@square_decorator
def square(n):
return n
# Use the decorated function
print(square(5)) # Output: 25
Lambdas
Lambdas are anonymous functions that do not have to be defined with a name. They are often used with higher-order functions such as map, reduce, and filter. Here's an example:
# Define a lambda function
square = lambda x: x**2
# Use the lambda function with map
numbers = [1, 2, 3, 4]
squared_numbers = list(map(square, numbers))
print(squared_numbers) # Output: [1, 4, 9, 16]
Python 3.7 offers many other advanced coding techniques such as comprehensions for dictionaries and sets, async and await, and many others. By mastering these techniques, you can take your coding game to the next level and write more efficient and powerful Python programs.
