Introduction to Batch APIs In modern Python applications, it’s common to access remote API using REST or other web-based technologies. Batch APIs are capable of processing multiple requests with a single call. You can use batch APIs to reduce the number of network calls to the remote service. This is ideal when you have to …

Python 3.6 added another way to do string interpolation that is called “f-strings” or Formatted string literals (PEP 498). The idea behind f-strings is to make string interpolation simpler. To create an f-string, you just need to prefix the string with the letter “f”. The string itself can be formatted in much the same way …
Python has some powerful features that allow you to introspect your code or the code of others. I created the following video tutorial to help you learn how that works. This tutorial is from the Python 101 Screencast Related Articles Python 101: Introspection
Python 3.5 added more support for Unpacking Generalizations in PEP 448. According to the PEP, it added extended usages of the * iterable unpacking operator and ** dictionary unpacking operators to allow unpacking in more positions, an arbitrary number of times, and in additional circumstances. What this means is that we can now make calls …
Python 3.6 added a new module called secrets that is designed “to provide an obvious way to reliably generate cryptographically strong pseudo-random values suitable for managing secrets, such as account authentication, tokens, and similar”. Python’s random module was never designed for cryptographic use but for modeling and simulation. Of course, you could always use the …
Python 3.6 added the ability to create Asynchronous Comprehensions and Asynchronous Generators. You can read about asynchronous comprehension in PEP 530 while the asynchronous generators are described in PEP 525. The documentation states that you can now create asynchronous list, set and dict comprehensions and generator expressions. Their example looks like this: result = [i …
