Question

Although working with sets is quick and easy in Python, sometimes we might want to find the union between two lists. Create a function called unite_lists, which uses a loop to go through both lists and return common elements. Do not use the built-in set function

a Collection
Steps for Completion
1. Define a function named unite_lists.
2. Using a for statement, iterate through the
two lists, while finding the common elements
in both lists without duplicates.
Snippet 6.109 shows an example output:
>>> unite_lists([2,4,6,8], [3,6,9,12])
[2, 4, 6, 8, 3, 9, 12]
1 # Write your code here
2 unite_lists = []
3 for items in a:
4
5
for numbers in b:
if items == numbers:
if items in c:
None
6
7
8
9
10 # Test your code here
11 if __name__ == '__main__':
12
13
else:
c.append(items)
print(unite_lists([2,4,6,8], [3,6,9,12]))

Expert Solution

Step 1

The source code of the program

def unite_lists(lst1, lst2):
result = []
for n in lst1 + lst2:
if n not in result:
result.append(n)
return result
if __name__ == '__main__':
print(unite_lists([2, 4, 6, 8], [3, 6, 9, 12]))
