Learn Python string concatenation with + operator, join(), format(), f-strings, and more. Explore examples and tips for efficient string manipulation.
As we have noticed, we can treat arrays as Lists but cannot constrain the data type in a list as it is done in an array. This will be understood much more in the next section. Python Built-in Array Module There are many other built-in modules in Python which you can read more about...
By all means skip this section if you already know this, but it is important to have a basic grasp of some key concepts if you are to avoid the frustration of finding that the conversions you are trying to accomplish are not allowed. The first thing to understand is the difference ...
This is an ordinary Python class, with nothing Django-specific about it. We’d like to be able to do things like this in our models (we assume thehandattribute on the model is an instance ofHand): example=MyModel.objects.get(pk=1)print(example.hand.north)new_hand=Hand(north,east,sout...
Again, you can evaluate the values and determine any conversions to apply. OrderID looks like an integer, so you can convert that using the toInteger() function. The orderDate column is certainly in a date format and will require us to format it using the datetime() function. Finally, ...
The hardware oversampling engine accumulates the results of ADC conversions. The accumulated output data can be right-shifted (and rounded) to provide selected bit-depth in relation to OSR. The output value is not updated every sampling period, but onc...
All the unit in these cases used to address these are in Gigabytes. There is a bit of mathematics required for the conversion of bytes to gigabytes. It is similar to converting meters to kilometres. Let us see how we can do the conversion in JavaScript. There are a couple of approaches ...
Here’s how to do it. First, go to the Add-ons menu in your spreadsheet and make sure you have Google Analytics installed (if you don’t, use Add-ons > Get add-ons… to enable it). Select Add-ons > Google Analytics > Create New Report: A new window will appear with several...

You may go through this list of actions: Use analytics tools to track user engagement and conversions Monitor server logs for any...
