Mastering flat_map in Python with List Comprehension

Image
Introduction In Python, when working with nested lists or iterables, one common challenge is flattening them into a single list while applying transformations. Many programming languages provide a built-in flatMap function, but Python does not have an explicit flat_map method. However, Python’s powerful list comprehensions offer an elegant way to achieve the same functionality. This article examines implementation behavior using Python’s list comprehensions and other methods. What is flat_map ? Functional programming  flatMap is a combination of map and flatten . It transforms the collection's element and flattens the resulting nested structure into a single sequence. For example, given a list of lists, flat_map applies a function to each sublist and returns a single flattened list. Example in a Functional Programming Language: List(List(1, 2), List(3, 4)).flatMap(x => x.map(_ * 2)) // Output: List(2, 4, 6, 8) Implementing flat_map in Python Using List Comprehension Python’...

Calculate Circle Area the Logic You Need to write in Python

In Python, you can calculate the circle area easily by using the function. The purpose of Python is to use in data analysis. You need this logic in many areas. You can use in your present finance projects or new ones. Benefits of function you can re-use the same code number of times. Area of Circle=pi*r*r Area of Circle Steps Given - You Can do Using Two Methods, Explained Both Methods I have given steps to calculate the  area of a circle using two different methods. First I followed by creating a user-defined function. Next, directly I ran the formula in the interpreter.   Method -1 Steps I have followed to Calculate Area Using Function Logged into Cent Os (Linux) Create .py module Import .py module into Python Execute .py module  1. Log in I have first logged into CentOS. You can see there '$'. 2. Creating .py module To create ".py" module. You can use the vi editor command. You need 'import decimal' to ...
