A list is an ordered data structure with elements separated by a comma and enclosed within square brackets
List:
Lists are used to store multiple items in a single variable.
Lists are one of 4 built-in data types in Python used to store collections of data, the other 3 are Tuple, Set, and Dictionary, all with different qualities and usage.
Example:
a list = ["shaun", "melendez", "lea"] print(a list)
Output:
[‘shaun’, ‘melendez’, ‘lea’]
The main motto of the topic is to find the common elements in the list .
we can write the code using and (&) function .
# initialize lists
a_list1 = [5, 6, 10, 9, 7, 1, 6]
b_list2 = [8, 6, 10, 3, 7, 10, 19]
# using set intersection to get number of identical elements
result = len(set(a_list1) & set(b_list2))
# printing result
print("Summation of Identical elements : " + str(result))
Output:
Summation of Identical elements : 3
