💡 Hint

Common Mistakes

Using a different parameter name than the one used inside the function causes a NameError.

The function parameter should be named 'name' because the print statement uses 'name'.

medium

Complete the code to define a function that adds two numbers and returns the result.

Python

def add_numbers(a, [1]):
    return a + b

result = add_numbers(3, 4)
print(result)

💡 Hint

Common Mistakes

Using a parameter name that does not match the variable in the return statement causes a NameError.

The second parameter must be named 'b' because the return statement uses 'b'.

3fill in blank

hard

Fix the error in the function call by completing the argument type correctly.

Python

def repeat_text(text, times):
    return text * times

result = repeat_text("Hi", [1])
print(result)

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

C3

D'3'

💡 Hint

Common Mistakes

Passing the number as a string causes the function to repeat the string incorrectly or raise an error.

The second argument must be an integer (3) to multiply the string correctly.

4fill in blank

hard

Fill both blanks to create a function that filters numbers greater than 5 from a list.

Python

def filter_numbers(numbers):
    return [num for num in numbers if num [1] [2]]

result = filter_numbers([2, 7, 4, 9])
print(result)

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

D7

💡 Hint

Common Mistakes

Using '<' instead of '>' will filter numbers less than 5.

Using the wrong number in the comparison changes the filter result.

The condition 'num > 5' filters numbers greater than 5.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps words to their lengths if length is greater than 3.

Python

words = ["apple", "cat", "banana", "dog"]
lengths = { [1]: [2] for word in words if len(word) [3] 3 }
print(lengths)

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

Aword

C>

D<

💡 Hint

Common Mistakes

Using '<' instead of '>' changes the filter condition.

Swapping key and value causes incorrect dictionary structure.

The dictionary comprehension maps each word to its length if the length is greater than 3.
