The Alibaba SDK for DirectMail does not support Python. It does support PHP, Java and C#. A very common use case for DirectMail is delivering emails for dynamic and static websites. For dynamic websites PHP is perfect. For static websites, integrating Function Compute with DirectMail is perfect. However, Function Compute does not support PHP. This means that you develop in one language on your desktop and another in the cloud.
In this article I will focus on the DirectMail REST API and include a real working example in Python.
# Correctly formatted date and time now = datetime.datetime.utcnow() # Date used by the HTTP "Date" header date = now.strftime("%a, %d %b %Y %H:%M:%S GMT") # Date used by the API parameter "Timestamp" utc = now.isoformat(timespec='seconds') + 'Z'
In this article, you will get some information on writing our own basic headless web scraping "bot" in Python with Beautiful Soup 4 on an Alibaba Cloud Elastic Compute Service (ECS) instance with CentOS 7.
Now we need to install our Python packages we will be using today, Requests and Beautiful Soup 4.
We will install these through PIP.
pip36u install requests pip36u install beautifulsoup4
Requests is a Python module that allows us to navigate to a web page with the Requests .get method.
Requests allows you to send HTTP/1.1 requests, all programatically through the Python script. There's no need to manually add query strings to your URLs, or to form-encode your POST data. Keep-alive and HTTP connection pooling are 100% automatic. We will be focusing on the Requests .get method today to grab a web page source.
Beautiful Soup is a Python library for pulling data out of HTML and XML files. It works with your favorite parser to provide idiomatic ways of navigating, searching, and modifying the parse tree.
We will be using Beautiful Soup 4 with the standard html.parser in Python to parse and organize the data from the web page source we will be getting with Requests. In this tutorial we will use the Beautiful Soup "prettify" method to organize our data in a more human readable way.
Lets make a folder called "Python_apps". Then, we will change our present working directory to Python_apps.
mkdir Python_apps cd Python_apps
In this article, we will discuss how you can use FlashText, a python library that is 100 times faster than RegEx to perform data analysis.
Before you proceed with your analysis, you need to clean your source data, even for the simplest text. This often includes searching and replacing keywords. For example, search the corpus for the keyword "Python," or replace all "python" to "Python."
As the name suggests, FlashText is one of the fastest ways to execute search and replace keywords. It is an open source python library on GitHub.
When using FlashText, begin by providing a list of keywords. FlashText uses this list to build an internal Trie dictionary. You then send it a string of text depending on whether you want to search or replace.
In today's article we will be exploring Alibaba Cloud Function Compute for DevOps with some example programs using Python 3. Our ultimate goal is to combine API Gateway, Function Compute, and Direct Mail to provide a contact form suitable for a static website hosted on OSS.
A pre-configured and fully integrated minimal runtime environment with TensorFlow, an open source software library for machine learning, Keras, an open source neural network library, Jupyter Notebook, a browser-based interactive notebook for programming, mathematics, and data science, and the Python programming language. The stack is built with the Intel MKL and MKL-DNN libraries and optimized for running on CPU.
Versions: TensorFlow 1.8.0, Python 3.6.3, Development preset 1, Libc 2.22, OpenBLAS 0.2.20, Python_enum34 1.1.6, NumPy 1.13.3, Ubuntu 16.04
If an Alibaba Cloud product does not provide an SDK for its APIs, you can use the generic calling method (CommonRequest) to call the product APIs. By using the CommonRequest calling method, you can call any API.
Alibaba Cloud Python SDK returns corresponding exceptions when an error occurs on the service side or the SDK side. These exceptions contain detailed error information, including the error code (ErrCode) and error message (ErrMsg).
You do not need to handle these returned errors. You only need to make corresponding modifications based on the error message.
DirectMail is a simple and efficient service to send email notifications and batch email quickly and efficiently without the need to build your own email server. DirectMail is a key product for serving Alibaba's own e-commerce platforms, which includes servicing Alibaba's record-breaking annual sales festival. Tens of millions of emails are sent every day through DirectMail by Alibaba and Alibaba Cloud customers.
DataV is a powerful yet accessible data visualization tool, featuring geographic information systems allowing for rapid interpretation of data to understand relationships, patterns, and trends. All packed into a user-friendly interface.
By integrating live dashboards, DataV can present and monitor business data simultaneously. This data-driven approach enables for well-organized data mining and analysis allowing the user to seize new opportunities that otherwise might remain hidden.
Data visualization capabilities are very important. A beautiful and clear charts can help you understand the data intuitively when you explore and analyze data, Data visualization also plays an important role in your interactions with customers, and it helps you communicate the quantitative characteristics of the data. From this perspective, making an eye-catching chart is an indispensable technology.
This training introduces the basic concepts of Python visualization, and the basic python visualization library Matplotlib as well as the two important third-party libraries based on matplotlib: pandas and seaborn. The training also introduces how to use Python visualization library for data analysis and processing.
