Static method: It is a general utility method that performs a task in isolation. Inside this method, we don’t use instance or class variable because this static method doesn’t take any parameters likeselfandcls. Also, readPython Class method vs Static method vs Instance method. ...
First-Class ObjectsIn functional programming, you work almost entirely with pure functions that don’t have side effects. While not a purely functional language, Python supports many functional programming concepts, including treating functions as first-class objects. This...
