Python Code: # Define a function 'unique_list' that removes duplicates from a listdefunique_list(l):# Create an empty list 'temp' to store unique elementstemp=[]# Iterate through the elements of the input list 'l'forxinl:# Check if the element 'x' is not in the 'temp' list (i....
Pandasprovides efficient data manipulation tools, and its DataFrame can be used to remove duplicates while maintaining order, suitable for dataframes or tabular data. This method converts the list into a pandas DataFrame, removes duplicates using thedrop_duplicates()function, and then converts the r...

third-party library,Pandas, also has aunique()function that works similarly but preserves the order of the items. The NumPy and Pandas solutions are ideal when these libraries are already in use in the codebase and don't need to be installed and imported simply to remove duplicates from a ...
An ABS constraint r=abs{x} states that the resultant variable r should be equal to the absolute value of the argument variable x. You can also add an ABS constraint using the abs_ function. Parameters: resvar –(Var) The variable whose value will be to equal the absolute value of the...
Now that we have a good understanding of sets in Python, let’s explore different methods to merge sets. Using the Union Operator The simplest way to merge two or more sets is by using the union operator (|). This operator combines elements from all sets and removes duplicates. ...
# Define a function called is_prime that takes a number x as input. # For each number n from 2 to x - 1, test if x is evenly divisible by n. # If it is, return False. # If none of them are, then return True. # def is_prime(x): ...
