1. Notice that both the ids are same.assert id("some_string") == id("some" + "_" + "string") assert id("some_string") == id("some_string")2. True because it is invoked in script. Might be False in python shell or ipython...
Advantages of Static Method in Python Using static methods in Python classes comes with several advantages. Static methods are: Safe to use. Since static methods cannot access the class or instance data, they cannot modify the class state. This method cannot change the behavior or affect a class...
Python arrays include two built-in methods for adding new elements. Which method you use depends on where within the array you want the new element to be added. Use the append() method to add a new element to the end of an array. The example below adds the integer 10 as a new eleme...
The context manager you previously wrote is a class, but what if you want to create a context manager method similar to the open() function instead? Simple: Python also supports writing context manager methods.To turn a method into a context manager, use the contextlib module:...
