If we call Duck, we'll see that we get back a new Duck object, and this Duck object has a quack method:>>> duck = Duck() >>> duck <__main__.Duck object at 0x7fb23cbea210> >>> duck.quack() Quack!While it is possible to dynamically create classes in Python, t's pretty ...
But sometimes, the outcomes of a Python snippet may not seem obvious at first sight.Here's a fun project attempting to explain what exactly is happening under the hood for some counter-intuitive snippets and lesser-known features in Python.While some of the examples you see below may not be...
Python language combines different Built-in functions, Built-in methods, and special variables. Let's understand Python's __file__ variable in detail. These
In this case, "__name__" is pronounced "dunder name."Let's use the Python shell to determine what the value of __main__ ?>>> __name__ '__main__' So, the value of __name__ is __main__.Let's try importing a Python module to see the value assigned to the module's __...
Structural pattern matching also excels at type checking. Strong type checking is usually discouraged in Python, but it does come crop up from time to time. The most common place I seeisinstancechecks is in operator overloading dunder methods (__eq__,__lt__,__add__,__sub__, etc). ...
In other words, data structures are similar to basic data types: they can be stored via variables, removed, changed, and more.Built-in data structures provide a standard and highly performant way to work with bulk data. However, there is simply no silver bullet or one-size-fits-all data ...
If it is not there, it tries b.__rmult__(a). If there is still not an operator for a*b, it raises an Error. A dunder a a __double under__ method that can be overwritten and that gives you ability to used shorter notations (see my example with generalised type, not just int...
