Best Practices for Handling Duplicate Elements in Python Lists

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

Python Function Argument: How to Pass it to Decorator

A decorator is a wrapper and provides additional functionality to a function. Also, it may modify the behavior, such as changing the return type/adding new abilities. Python Decorators Precisely, it is another form of function pointers . Also, it accepts function argument, then either wraps the function or returns a new one. Moreover, it modifies the inputs/outputs supplied to it. It helps you add behavior to functions (objects) dynamically (without changing the function behavior). Function Argument Below, you will find an example of passing a function argument to a decorator. The below function modifies inputs and returns output. def to_upper(func):     text=func()     if isinstance(text,str):         return text.upper() def say():     return "welcome" def hello():     return "hello"      a = to_upper(say) print(a)  b = to_upper(hello) print(b)   Output WELCOME HELLO ** Process exited - Return Code: 0 ** Press Enter to exit terminal References How to write th

Python: How to Write Logic to Print Triangle

Here's an example to print Triangle in Python. It's the best interview question. You can expect this type of question in your interview. So this is useful to practice it. How to Print Triangle Logic to Print Trianagle max = 8 for x in range(1, max + 1): for y in range(1, x + 1): print y, print Result 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 1 2 3 4 5 6 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8   Also, Read Python while loop Python for loop example

Python Advanced For Loop With Example

Basically, For Loop reads input value and stores in a variable. So For Loop in Python needs two arguments. The two arguments are VARIABLE and IN. So far so good. The next part of the article and examples well explained how it works and how to get the index for each input supplied.
