Assert statement usage in Python - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if the variable age is at least 18 using an assert statement.

Python

age = 20
assert [1], "Age must be at least 18"

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

Aage > 18

Bage >= 18

Cage = 18

Dage < 18

💡 Hint

Common Mistakes

Using assignment (=) instead of comparison (>=).

Checking if age is less than 18 instead of greater or equal.

The assert statement checks if the condition age >= 18 is True. If not, it raises an AssertionError with the message.

Complete the code to assert that the list numbers is not empty.

Python

numbers = [1, 2, 3]
assert [1], "List should not be empty"

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

Alen(numbers) == 0

Bnumbers is None

Cnumbers == []

Dlen(numbers) > 0

💡 Hint

Common Mistakes

Checking if length equals zero instead of greater than zero.

Comparing the list directly to an empty list incorrectly.

The assert checks that the length of the list is greater than zero, meaning it is not empty.

hard

Fix the error in the assert statement that checks if score is between 0 and 100 inclusive.

Python

score = 85
assert 0 <= score and score [1] 100, "Score must be between 0 and 100"

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

A<=

B==

C>

💡 Hint

Common Mistakes

Using 'or' which allows invalid scores.

Using '==' which only checks equality, not range.

The condition must use 'and' to ensure score is both greater or equal to 0 and less or equal to 100.

4fill in blank

hard

Fill both blanks to assert that the string name is not empty and has length less than 10.

Python

name = "Alice"
assert [1] and [2], "Name must be non-empty and shorter than 10 characters"

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

Alen(name) > 0

Blen(name) == 0

Clen(name) < 10

Dlen(name) > 10

Attempts:

3 left

💡 Hint

Common Mistakes

Using length equal to zero instead of greater than zero.

Checking length greater than 10 instead of less than 10.

The assert checks that the name length is greater than zero and less than ten.

5fill in blank

hard

Fill all three blanks to create a dictionary valid_scores with keys as uppercase names and values as scores greater than 50.

Python

scores = {"alice": 60, "bob": 45, "carol": 75}
valid_scores = { [1]: [2] for name, score in scores.items() if score [3] 50 }

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

Aname.upper()

Bscore

C>

Dname.lower()

Attempts:

3 left

💡 Hint

Common Mistakes

Using name.lower() instead of upper().

Using score less than or equal to 50.

Swapping keys and values in the comprehension.

The dictionary comprehension uses uppercase names as keys, scores as values, and filters scores greater than 50.
