Best Practices for Handling Duplicate Elements in Python Lists

Image
Here are three awesome ways that you can use to remove duplicates in a list. These are helpful in resolving your data analytics solutions.  01. Using a Set Convert the list into a set , which automatically removes duplicates due to its unique element nature, and then convert the set back to a list. Solution: original_list = [2, 4, 6, 2, 8, 6, 10] unique_list = list(set(original_list)) 02. Using a Loop Iterate through the original list and append elements to a new list only if they haven't been added before. Solution: original_list = [2, 4, 6, 2, 8, 6, 10] unique_list = [] for item in original_list:     if item not in unique_list:         unique_list.append(item) 03. Using List Comprehension Create a new list using a list comprehension that includes only the elements not already present in the new list. Solution: original_list = [2, 4, 6, 2, 8, 6, 10] unique_list = [] [unique_list.append(item) for item in original_list if item not in unique_list] All three methods will result in uni

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
