We can prove that to ourselves by passing that object to Python's built-in type function:>>> type(colors) <class 'list'> Lists are ordered collections of things.We can create a new list by using square brackets ([]), and inside those square brackets, we put each of the items that ...
in COLLECTION: ... do things ... it's valuable to note that Python works over the notion of iterator for iterations. What decides which value will come and its order/sequentiality it's the iterator. some objects outputs values in a different order they are added to the object (e.g. ...

We don't learn by reading or watching.We learn by doing.That means writing Python code. Practice this topic by working on theserelated Python exercises. deep_add: Deeply sum numbers in an iterable-of-iterablesremove_empty: Remove all empty directories recursivelybullet points: Utilities for pars...
In Python, map, filter, and reduce are built-in functions that provide powerful tools for working with sequences of data. map() in Python The map() function takes a function and an iterable (such as a list) as input and applies the function to each element of the iterable. It returns...
In this tutorial, you learned what lazy evaluation in Python is and how it’s different from eager evaluation. Some expressions aren’t evaluated when the program first encounters them. Instead, they’re evaluated when the values are needed in the program. This type of evaluation is referred ...
In the example above, only authenticated users are allowed to create_post(). The logic to check authentication is wrapped in its own function, authenticate(). This function can now be called using @authenticate before beginning a function where it’s needed & Python would automatically know that...

The full expected lifecycle of the Python 2.7 series is detailed in PEP 373. Some key consequences of the long-term significance of 2.7 are: As noted above, the 2.7 release has a much longer period of maintenance when compared to earlier 2.x versions. Python 2.7 is currently expected to ...
