There are a few different approaches for writing tests for date and/or time-sensitive functionality. One could choose to add a sleep() in the test, which would guarantee that the time passed, but that also has the downside of increasing the run time of the test.
Here’s an example of adding date and time validation to a DateTimeField in a serializer in the Django Rest Framework (DRF).
If your Python project has a very short list of required packages (in requirements, pipfile, etc), it’s easy to see all packages you have. But on large projects, the dependencies can run pretty long, not to mention the dependencies for the required packages. And what about learning more about those dependencies?
Most of you might be too young to know this but there was time that the phone in your house - not in your pocket! - would ring and gasp! you had no idea who was calling! You had to ANSWER the phone to find out. :scream:
In a previous post I wrote a summary of the things I learned about gRPC. Here I will talk about the prototype app I wrote to test gRPC and gRPC-Web.
I recently spent some time researching gRPC and this post is a summary of what I learned. I also wrote a prototype application to test gRPC and gRPC-Web with Python and JS. The JS client takes a string from user input and test if it’s a palindrome. The code can be found on GitHub and in a future post I will comment on it.
Yes! Indentation, or leading white space at the beginning of a line is required in Python. You can read more about why that is important here. And here is the part of the style guide convention for indentation (PEP 8).
Python has three similar data structures that can hold an unordered collection of elements: list, tuple and set.
OR: Run a Python script with arguments You can add arguments to the command line when running python scripts by importing the sys module from Python’s standard library and using its argv function.
Given a nested dictionary like this: dog_breeds = { 'Labrador Retriever': {'life_span': 14, 'male_weight': '36 Kg', 'female_weight': '32 Kg'}, 'Beagle': {'life_span': 15, 'male_weight': '11 Kg', 'female_weight': '10 Kg'}, 'German Shepherd': {'life_span': 13, 'male_weight': '40 Kg', 'female_weight': '32 Kg'}, 'Jack Russell Terrier': {'life_span': 16, 'male_weight': '8 Kg', 'female_weight': '8 Kg'}, 'Rottweiler': {'life_span': 10, 'male_weight': '60 Kg', 'female_weight': '48 Kg'} } here’s a way to display its content sorted by key:
From Python’s official documentation: “A profile is a set of statistics that describes how often and for how long various parts of the program executed.”
Problem: create a map of the letters and indices in a string. My first approach was to loop over the string using range(len(s)), and checking if the letter exists in the map before adding it:
