Using the Python return Statement Effectively

The Python return statement is a key component of functions and methods. You can use the return statement to make your functions send Python objects back to the caller code. These objects are known as the function’s return value. You can use them to perform further computation in your programs. Using the return statement effectively is a core skill if you want to code custom functions that are Pythonic and robust. In this course, you’ll learn: How to use the […]

A library of functions to compute climate indices from observations or model simulation

xclim: Climate indices computations xclim is a library of functions to compute climate indices from observations or model simulations. It is built using xarray and can benefit from the parallelization handling provided by dask. Its objective is to make it as simple as possible for users to compute indices from large climate datasets and for scientists to write new indices with very little boilerplate. For example, the following would compute monthly mean temperature from daily mean temperature: import xclim import […]

Windows Task Manager with special features written in Python

Killer Windows Task Manager with special features, written in Python. Tired of trying to kill processes with the default Windows Task Manager? Selecting one by one? So this is for you. Killer is an app with concise design which displays the processes, let search between them, order by pid/name/cpu/memoryand kill multiple apps (or even all) at once. Besides that, you can also kill the children of the selected process(es),which means, all the other processes created by these (no survival chance). […]
