Python is a powerful programming language that has started regaining its fame for its usage in the Data Science along with the latest technologies like R and etc. Having said that, let us take a look at the tiny winy bits of concepts to get ourselves stronger in this programming language. ...
What is a built-in namespace in Python? A built-in namespace contains the names of built-in functions and objects. It is created while starting the python interpreter, exists as long as the interpreter runs, and is destroyed when we close the interpreter. It contains the names of built-i...

If the items in a tuple are mutable, then you’ll be able to change them even if the tuple itself is immutable. In other words, the immutability of Python tuples refers to the references it directly holds. It doesn’t extend to the referenced objects themselves. In general, putting mutab...

There are other expressions in Python that lead to lazy evaluation. In this section, you’ll explore the main ones.Other Built-In Data TypesThe Python built-ins zip() and enumerate() create two powerful built-in data types. You’ll explore how these data types are linked to lazy ...
