Importing a python module means to load the namespace of what is available in that python module, into memory. Specifically, writing "import " tells python to look for a module with that name on your python path (typically a folder), and if it finds such an object, to then run that o...
In thisPython NumPy tutorial, I will explain what thenp.where() in Pythonis, its syntax, the parameters required, and its return value. I will explain how to applynp.where in PandasPython with different examples. To create or modify columns conditional, we can use the np.where() function...
Note: To learn more about mutability and immutability in Python, check out the Python’s Mutable vs Immutable Types: What’s the Difference? tutorial.You can replace or update a value in a list by indexing it on the left side of an assignment statement:...
Strings are immutable Data Types in Python, which means that once a string is created, it cannot be changed. In this module, we will learn all about strings in Python so as to get started with strings. Watch this video on Python String Operations: So, without any further ado, let’s ...

Dictionaries in Python provide a means of mapping information between unique keys and values. You create dictionaries by listing zero or more key-value pairs inside braces, like this:Python Copy capitals = {'France': ('Paris', 2140526)} A key for a dictionary can be one of three types:...
That means that the order in which they are written in the source file is irrelevant. Notes that link to an entire verse using the empty parameter `{}` are placed as the first, and if there are more than one of them, then their order is reverse to that in the source file, as ...
