In the main() function, we created an array arr1 that contains integer elements. Then we used the distinct() method to get the distinct elements of array arr1 and assigned the result into arr2. After that, we printed the elements of array arr2 on the console screen....
One can utilize thenumpy.unique()function to count the occurrences of unique element’s in NumPy Array . The function requires the input of an array and returns all the unique elements present within the array in ascending order. To obtain thenumber of times each element is repeatedin the ar...

To select distinct elements across multiple DataFrame columns, we need to check if there are any duplicates in the DataFrame or not and if there is any duplicate then we need to drop that particular value to select the distinct value. For this purpose, we will use DataFrame['col'].uniqu...
