Basic assert statement in PyTest - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to assert that the sum of 2 and 3 equals 5.

PyTest

def test_sum():
    result = 2 + 3
    assert result [1] 5

💡 Hint

Common Mistakes

Using '=' instead of '==' in the assert statement.

Using '!=' which checks for inequality.

The assert statement checks if the expression is true. Here, result == 5 verifies the sum is correct.

2fill in blank

medium

Complete the code to assert that the length of the list is 4.

PyTest

def test_list_length():
    items = [1, 2, 3, 4]
    assert len(items) [1] 4

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

💡 Hint

Common Mistakes

Using '<' or '>' which check less or greater than, not equality.

Using '!=' which checks for inequality.

The assert checks if the length of items is exactly 4 using ==.

3fill in blank

hard

Fix the error in the assert statement to correctly check if the variable is True.

PyTest

def test_is_active():
    is_active = True
    assert is_active [1] True

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

💡 Hint

Common Mistakes

Using '=' instead of '==' in assert.

Using 'is' which is for identity, not equality.

The correct way to compare values in an assert is with ==. Using = causes a syntax error.

4fill in blank

hard

Fill both blanks to assert that the variable score is greater than 50.

PyTest

def test_score():
    score = 75
    assert score [1] [2]

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

A>

B50

C==

D<

Attempts:

3 left

💡 Hint

Common Mistakes

Using '==' instead of '>' for greater than check.

Using '<' which checks less than.

The assert checks if score is greater than 50 using > and the number 50.

5fill in blank

hard

Fill all three blanks to assert that the length of names is less than 5 and the first name is 'Alice'.

PyTest

def test_names():
    names = ['Alice', 'Bob', 'Charlie']
    assert len(names) [1] [2] and names[0] [3] 'Alice'

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

💡 Hint

Common Mistakes

Using '>' instead of '<' for length check.

Using '=' instead of '==' for string comparison.

The assert checks two things: length of names is less than 5 (< and 5), and the first name equals 'Alice' (==).
