Python Sets [ 20 exercises with solution]

A set object is an unordered collection of distinct hashable objects. It is commonly used in membership testing, removing duplicates from a sequence, and computing mathematical operations such as intersection, union, difference, and symmetric difference.

You may read our Python sets tutorial before solving the following exercises.

11. Write a Python program to create a shallow copy of sets. Go to the editor

Note : Shallow copy is a bit-wise copy of an object. A new object is created that has an exact copy of the values in the original object.

Python: Tips of the Day

Inserting if statements using conditional list comprehensions:

x = [1, 2, 3, 4, 5, 6]
result = []
for idx in range(len(x)):
    if x[idx] % 2 == 0:
        result.append(x[idx] * 2)
    else:
        result.append(x[idx])
result

Output:

[1, 4, 3, 8, 5, 12]

[(element * 2 if element % 2 == 0 else element) for element in x]

Output:

[1, 4, 3, 8, 5, 12]

[element * 2 for element in x if element % 2 == 0]

Output:

[4, 8, 12]
