reduce() in Python (with examples)

reduce() in Python (with examples)

The reduce(fun,seq) applies a specific function to all of the list components mentioned in the sequence handed along. The “functools” module contains the definition for this function. To reduce the list on a single value, the reduce() function applies the fn function with two arguments cumulatively to the list items, from left to right. reduce(), unlike the map() and filter() procedures, is not a Python built-in function. The reduce() function belongs to the...
Bitwise operators in Python

Bitwise operators in Python

Bits are a stream of binary numbers that computers use to store many types of data. It ultimately comes down to ones and zeros, whether you’re working with text, photos, or videos. Bitwise operators in Python allow you to alter individual bits of data at the most granular level. ...
Recursion in Java

Recursion in Java

Recursion is the core of programming and is used in many related concepts like sorting, tree traversal, and graphs. In addition, recursion has a wide variety of uses in data structures and algorithms, and even though it is a complex concept, it can be used to make the task easier. ...
Calculating Factorial in C++

Calculating Factorial in C++

We will use C++ to write programs to calculate the factorial of a number. We will take the number as an input from the user and then print the factorial of that number in the console. We will use two methods to calculate the factorial of the number, the first is by performing iteration with the help of loops, and the second is by using recursion. ...
How to plot in Python

How to plot in Python

In this article, we illustrate how to use each of the four most popular Python plotting libraries—Matplotlib, Seaborn, Plotly, and Bokeh—as well as a couple of promising newcomers: Altair, with its expressive API, and Pygal, with its beautiful SVG performance. We’ll also take a look at pandas’ extremely useful plotting API. ...
