Using the code below, causes one of my Cores to run at 100%. If I add a time.sleep(.1) to the while loop, the core then runs at a minimal level. I do not seem to miss messages but my test system is lightly loaded. According to the notes above, the MQTT loop is run in anot...
When we think about repeating a task, we usually think about theforandwhileloops. These constructs allow us to performiterationover a list, collection, etc. However, there's another form of repeating a task, in a slightly different manner. By calling a function within itself, to solve a sm...

List comprehensions provide an alternative syntax to creating lists and other sequentialdata types. While other methods of iteration, such asforloops, can also be used to create lists, list comprehensions may be preferred because they can limit the number of lines used in your program. ...

The following Python code uses recursion to determine the sum of a set of numbers; notice that the code avoids awhileor a forloop. # Define a recursive function to calculate the sum of numbers from 1 to ndefsum_recursive(n):return1ifn==1elsen+sum_recursive(n-1)# Test the recursive su...
The array_shift function in PHP is an essential tool for manipulating arrays. This function works by removing the first element from an array and returning its
else can be used in conjunction with loops in some programming languages. for example, in python, you can use else with a for or while loop to specify code that should run after the loop finishes, unless the loop was terminated with a break statement. why would i use else instead of ...
