Strong static typing helps detect errors at compile time. Variables in dynamically typed languages like Ruby or Python can receive different data types over the time. In Java, once a variable is declared to be of a certain data type, it cannot hold values of other data types. ...
Membership tests are commonly useful when you’re determining if a particular object exists in a given container data type, such as a list, tuple, set, or dictionary. To perform this kind of test in Python, you can use the in operator:...
