A Value List can be used for Boolean data types. For Boolean data types, the Value List contains two values: true and false. The true value is always the first value in the list. The values specified in the Value list are used in Python for specifying the value. See, for example,...
Python >>> a = ['foo', 'bar', 'baz', 'qux'] >>> len(a) 4 any() takes an iterable as its argument and returns True if any of the items in the iterable are truthy and False otherwise: Python >>> any([False, False, False]) False >>> any([False, True, False]) True...
This means, not only can we use objects, but we can define our own classes of objects. A class is just another name for a type in Python. We have been working with types (i.e. classes) since the first chapter of the text. Examples of classes are int , str , bool , float and ...
A namedtuple-style library for defining immutable sum types in Python. (Get it on PyPI)You may know sum types under a different name – they're also referred to as tagged unions, enums in Rust/Swift, and variants in C++. If you haven't heard about them yet, here's a nice ...
#container2{float:left;border-radius:5px;border-top:1pxsolid#CCC;}.left{float:left;}.border{border-radius:5px;}.t-border{border-top:1pxsolid#CCC;} I understand the thought process around defining basic classes to be reused through html, but doesn't this mean you have to go back and ...

Name: ARR_DELAY, Length: 14, dtype: float64 The string names used in the previous step are a convenience that pandas offers you to refer to a particular aggregation function. You can pass any aggregating function directly to the .agg method, such as the NumPy mean function. The output is...
