Subset and superset checks in Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if set A is a subset of set B.

Python

A = {1, 2, 3}
B = {1, 2, 3, 4, 5}
result = A.[1](B)
print(result)

💡 Hint

Common Mistakes

Using 'issuperset' instead of 'issubset'.

Using 'union' or 'intersection' which return new sets, not booleans.

The issubset method checks if all elements of set A are in set B.

medium

Complete the code to check if set B is a superset of set A.

Python

A = {1, 2}
B = {1, 2, 3, 4}
result = B.[1](A)
print(result)

💡 Hint

Common Mistakes

Using 'issubset' instead of 'issuperset'.

Using set operations that return sets instead of booleans.

The issuperset method checks if set B contains all elements of set A.

hard

Fix the error in the code to check if set A is a subset of set B.

Python

A = {5, 6}
B = {4, 5, 6, 7}
result = A.[1](B)
print(result)

💡 Hint

Common Mistakes

Using non-existent methods like 'issuper' or 'subset'.

Confusing 'issubset' with 'issuperset'.

The correct method to check if A is a subset of B is issubset. Other options are invalid or incorrect.

4fill in blank

hard

Fill both blanks to create a dictionary of words and their lengths, including only words longer than 3 letters.

Python

words = ['apple', 'bat', 'carrot', 'dog']
lengths = {word: [1] for word in words if len(word) [2] 3}
print(lengths)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the word itself instead of its length.

Using '<' instead of '>' causing wrong filtering.

We use len(word) to get the length, and filter words with length greater than 3 using >.

5fill in blank

hard

Fill all three blanks to create a dictionary with uppercase keys and values only if the value is greater than 0.

Python

data = {'a': 1, 'b': 0, 'c': 3}
result = { [1]: [2] for k, v in data.items() if v [3] 0 }
print(result)

Attempts:

💡 Hint

Common Mistakes

Using original keys instead of uppercase keys.

Filtering with '<' instead of '>'.

Using keys as values by mistake.

The keys are converted to uppercase with k.upper(), values are v, and we filter values greater than 0 using >.
