How to find Duplicate Elements from a List in Python

A list in Python can have any number of duplicate elements. To find duplicate elements from a list, you can simply loop through the list and check for matching items as shown in the example code below:

def find_duplicates(list):
    duplicates = []
    for item in range(0,len(list)-1):
        if list[item] == list[item+1]:
    return duplicates

fruits = ["banana", "apple", "grapes", "mango", "apple", "watermelon", "banana"]
result = find_duplicates(fruits)
print("Duplicate elements in the list = ",result)

The output of the above code is as follows:

Duplicate elements in the list = ['apple', 'banana']
