Common elements of Two list- Python Code

You are required to take two lists, say for example these two:

  a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]
  b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]

and write a program that returns a list that contains only the elements that are common between the lists (without duplicates). Make sure your program works on two lists of different sizes.

Extras:

1. Randomly generate two lists to test this
2. Write this in one line of Python (don’t worry if you can’t figure this out at this point – we’ll get to it soon)

Here is the solution to this simple problem

#   program to find out common elements in these two list
#   program by      : rakesh kumar

a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89] 
b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
common=[]
a = set(a)
b = set(b)
for x in a:
    if x in b:
        common.append(x)
print(common)

The output of the above program is like

$ c:/python37/python.exe c:/Users/as/Desktop/common_element.py
[1, 2, 3, 5, 8, 13]
