If we want to split a string to list based on whitespaces, then we don’t need to provide any separator to the split() function. Also, any leading and trailing whitespaces are trimmed before the string is split
In fact, you’ll find that .iterdir() is generally more efficient than the glob methods if you need to filter on anything more complex than can be achieved with a glob pattern. However, if all you need to do is to get a list of all the .txt files recursively, then the glob method...
The idea is to write filters that can operate in templates where auto-escaping is either on or off in order to make things easier for your template authors. In order for your filter to know the current auto-escaping state, set the needs_autoescape flag to True when you register your ...
To return a tuple in your Python function, simply create your tuple object and return it in your function as you would return any other value, or simply list all components of your tuple in the return statement.

Creating custom fields requires a bit of attention to detail. To make things easier to follow, we’ll use a consistent example throughout this document: wrapping a Python object representing the deal of cards in a hand ofBridge. Don’t worry, you don’t have to know how to play Bridge ...
