In this article, we show how to reference elements in an array in Python. So imagine you've created an array in Python. How do you then reference the individual elements of the array? For example, say you want the third element of the 2nd row. How do you reference this? So we go ...
This kind of import statement brings the name sqrt() into your current namespace, so you can use it directly without the need to reference the containing module. If you’re using modules, such as math or random, then make sure not to use those same names for your custom modules, functio...
The fastest (and easiest?) way is to use a slice that steps backwards,-1. ExampleGet your own Python Server Reverse the string "Hello World": txt ="Hello World"[::-1] print(txt) Try it Yourself » Example Explained We have a string, "Hello World", which we want to reverse: ...
The dictionary unpacking operator (**) is an awesome feature in Python. It allows you to merge multiple dictionaries into a new one, as you did in the example above. Once you’ve merged the dictionaries, you can iterate through the new dictionary as usual....

This all means that you don’t pass the reference to self in this case because self is the parameter name for an implicitly passed argument that refers to the instance through which a method is being invoked. It gets inserted implicitly into the argument list. How to Define a Function: Use...
But I want to tell you one thing: Python does not have the concept‘call by value’like languages likeC,C++,Java, etc. Instead, it passes the object reference by value. This means you pass the immutable objects, such as integers and tuples, to the function argument; it acts like a ...
In Python, Matplotlib allows you to add trendlines to your plots easily. The most common way to calculate a trendline is through linear regression, which fits a straight line to your data points. Adding a Simple Linear Trendline To add a simple linear trendline to your Matplotlib plot, you ...
We can reference our list by using the variable “jobs” that we declared above. How to Create a List in Python You can initialize a list in Python using square brackets, the list() method, list multiplication, and a list comprehension. Square brackets let you initialize an empty list, ...
Python HOWTOs are documents that cover a single, specific topic, and attempt to cover it fairly completely. Modelled on the Linux Documentation Project’s HOWTO collection, this collection is an effort to foster documentation that’s more detailed than the Python Library Reference. ...
